We headed to the dyno this morning with a MK7 Vw Golf 2.0 TDI 150ps, our customer has been running the CRDT for a few weeks now and has been over the moon
I'll let the graph do the talking
(http://i26.photobucket.com/albums/c109/ABYSS69/2013%20dtuk%20dyno/image_zps9dd8c901.jpg)
196.1bhp and 327.8lbft/445nm

Do the GT and GTD run the same turbo?

Doubt it - the 140 and 170 variants of the 2.0TDI CR in the last gen Golf/Scirocco/Passat didn't.

What figures can I expect from my mk7 gtd with a remap courtesy of you guys?
-
Stage 2: 235ps and 500 Nm!

So what is the difference between stage 1 and 2 accept for the 15bhp?? confused.com

Single channel (stage 1) and multi channel (stage 2) box modification. Single channel only plugs into the common rail, second channel plugs into the turbo pressure sensor. The box knows a little more about what the car is up to when it makes changes to boost the power.

thanks, so if I wanted to keep the car as unmodified (undetectable) as possible I would be better with a stage 1?

Both channels are supposed to be undetectable according to all the mod-box sellers. The box intercepts the signal from the car's own ECU and modifies it. There is supposed to be no feedback to the ECU to let it know a box is in place or something fishy is going on (in theory!). Some people here have had very good experiences from boxes, I saw a massive increase in car performance when I trialled one, but lack of grip with my Bridgestone tyres put me off keeping it.

so with one fitted are we talking on par with GTI performance?

Forget being on a par with a GTI below 30mph (you can't get all that power down quick enough), above 30mph, I would say that it exceeds a standard MK7 GTI - like Hyperspace on the Millenium Falcon (OK, slight exaggeration).
I find the bite/release of the autohold really hinders a quick move-off from standstill - it always feel like if I do it too quickly, i'll stall the car.
In Gear, with 26PS less than the MK6 GTI, the unaltered, stock MK7 GTD exceeds it in 4th/5th/6th from 40-80mph.
With dual channel box fitment and 15PS more than the standard MK7 GTI, how do you think it will fare against one? I'd take an educated guess that over the 40-80mph range, a GTD with only 210PS would keep up with a 220PS MK7 GTI due to the extra torque.
My overall mpg didn't drop with the box I trialled. The extra power will probably only come into play for 5% of your drive (unless you drive like a nutter), but it's nice to have it in reserve.
Keep thinking about getting another box, if it ever stopped raining then my Bridgestones would not be an issue.
-
Is it wrong that the thought of a remap on my GTD (when it arrives) gives me a twitch :laugh: :whistle:
-
A nervous twitch as only tuning boxes available at the minute :wink:

That would be a very nervous twitch when you floor it in 3rd at 60mph, in the wet, with Bridgestones and the traction control starts earning its keep!
Still got the curiosity for a group visit sometime, Chris?
-
I will be purchasing the box in the next month or two. But what I don't understand is when people say that they won't bother to inform their insurance company. I spoke to mine speculatively to find out how much it would increase my annual premium by...100quid they said. That's nowt, prefer to be fully insured incase the worst happens
-
To some people, £100 is worth dodging on the assumption that they won't crash, but with a £26k car I wouldn't take the risk. Some insurers won't touch a performance mod at all, so for those they have to ride out the risk or delay buying until renewal time with a mod friendly insurer.
Andrew mentioned an insurance "scheme" a while back - maybe the mod is declared primarily as an economy improvement device through this scheme and looked upon more favourably by most insurers?
-
I'm insured with Admiral and I was advised this increase was based upon the fact the box didn't exceed the 20% power increase (220bhp box) however the 235bhp box would bump up the additional quote considerably.
Monkeyhanger...what box did you have? 220 or the 235? Just wonder if the extra 15 will be particularly noticeable

If you do venture up, give me a shout. I'm not far off and am very tempted by the systems.

It was a different supplier's box, another dual channel system, comparable to the 235 in output. Considering I was using Shell V-power at the time I trialled the box (which made my car feel 10% slower without the box on, it was definitely slower than my 170 Scirocco), I was maybe only achieving around 220PS on full setting for what should have been a 241PS system, and that was mental - 235PS should be noticeably better.

We usually say a minimum of 500 miles, give the breaks a chance to bed in

The 235 version or the 220? Be keen to here how you get on. Been waiting for a review from someone and the fact youve had one or two be keen to see how it compares.

OK, here it is, done about 40 miles in it since fitment, this is the dual channel CRDT-2 box (rated 235PS)
Firstly, my car has been running a bit sh!tty in the 50 miles pre-box. Smack in the middle of a spell of DPF regenning, last night I had to give my cousin a jump-start when he flattened his battery in Newcastle City Centre last night and called me up, in prime pub-kicking out time. Spent 20 mins crawling around the 1/2 mile of road surrounding the Central train station, which made things worse and then 10 mins of 2000 rpm idling while he tried to get his sh!tty Citroen people carrier to splutter into life.
After a short spell at the Metrocentre this morning, I headed out to DTUK when Andrew confirmed he could meet me (and save me waiting for the postie on Tuesday). After getting there, Andrew fitted the box off his Skoda onto mine to see how it runs (set at 4+1, Andrews recommended top setting). The industrial estate consists of a 3/4 mile long road, and it was empty, so I did a quick spurt to 80mph and back down to sensible levels. Huge difference. Did same on the way back. Andrew then put the software onto the new box and fitted it to my car. Repeated the blast along the industrial estate, my box seemed a tiny bit better, or maybe I was just more confident in it's use. Came back, then had a chat with Andrew about TDIs we've had in the past etc (for about an hour!!!)
Firstly, I would say that I prefer this box to the TDI-tuning box I trialled - they are 2 very different animals.
The TDI-tuning box is raw and savage, some people might prefer that, but for me a sudden surge of power that causes wheelspin at 60mph in 3rd when you put your foot down is a bit of a widow-maker. At times with that box on setting 7, I felt I could quite easily James Dean the car.
The CRDT-2 has a much smoother and linear development of power - as smooth as the GTD's stock power range, but just more of it. Unlike my experiences with the TDI-tuning box, the idling was as smooth as stock - I experienced lumpy idling with the TDI-tuning box, but Buddy hadn't noticed on his. When we took my dad's TDI-tuning box off his MK5 GT 170 to trade in for his DSG GTD, his idling became smoother.
The car ran at the hot end of the spectrum for the 40 miles (24 miles home and 16 miles going to pick the missus up from work) I drove around on after fitting the box (minimum 95C, but staying at 102C for a good 10 mins, and then being happy to be sat around 97-98C for most of the time). I wasn't sure whether the running hot was down to me booting it a bit, or whether it was a continuation of the DPF regen that had been going on. I do think my stock GTD was running on the cold side, as if this was the main cause of my slightly poor mpg and frequent DPF regen.
A few days will tell if the boxed GTD has a preference for running at 95-97C, as my Scirocco did, if so, I might see my mpg and regen interval improve on that score alone.
The car feels complete now, like it was meant to be. At stock i'm feeling it is no faster than my Scirocco 170TDI.
Got onto the A19 at Killingworth, up a long and steep sliproad from the road below. Me and a Civic Type R got on the 2 lane sliproad at the same time and I annihilated the R. It was trying very hard, but not even close. Those things have no torque so maybe a standard GTD would outdo them up a hill (just).
Got home and 90 mins later I went to pick up the missus from work (overtime). On my rolling start run onto the coast road, for which I have measured previous cars performance against by the speed at which I pass a sign, I managed 88mph (it was quiet and I took it straight back down to 75 :whistle:), compared to 81mph average on my GTD and 83mph average on my Scirocco.
The other thing that seems to have improved my drive is pull away from a standstill. The worst thing about the auto handbrake is that I always pull away ultra cautiously until after the autohold has fully let go - it feels like if you give it some for a quick getaway then you'll stall (it probably won't but it feels that way). My car doesn't feel like that any more, the car feels like it'll easily overcome the bite of the autohold for a better getaway. You've got to have a bit of restraint in 2nd - seems the easiest point of an acceleration move to wheelspin if you're not careful.
Over the moon with the box, and on the assumption that I won't get any more regens than I get already (time will tell), i'll have no regrets at all.
I reset my MFD "since start" mpg reading when I left DTUK. It had been an abysmal 41mpg due to all the regenning which followed the previous night's events. By the time I got home (24 miles later), it was up to 55mpg. I suspect that like the TDI-tuning.co.uk box, the indicated mpg will be somewhere in the region of 15% optimistic at the higher settings, making an actual 47mpg far more likely (about what I would have expected from stock with as much hooning around as I did from a hot start).
I will keep you updated with actual mpg/regen info. In fact I might top the car back up tomorrow just so we can see a "whole tank" mpg that isn't biased by the sh!tty run I had between filling up and fitting the box.

Great write up! Happy to finally read a review from Mr Joe public giving an honest opinion.
It sounds like you rate the box, but I thought there would be a mind blowing difference but it doesn't sound like it. I think the TDI-tuning box seems more appealing to me, but wheel spinning at 60mph would make me sh*t bricks in the wet. Maybe adding the pedal box further down the line would be an option.
I bet smashing the R put a smile on your face :laugh:

I'd rather keep my underpants clean while pressing on the throttle, than wheelspinning in 3rd at 60mph in the wet and hoping the traction control keeps me in a straight line (as it didn't on my 1st experience - I was drifting a little). The TDI-tuning box is a bit more of a rollercoaster ride, so you might find it more fun, but scary at the same time.
For me though, the smooth power delivery and the fact that it idles normally, rather than like a cold BMW diesel is what appeals to me. Progressive application of the power is going to be a lot more mechanically sympathetic too. The TDI-tuning box can bite back a bit (might not be an issue if you don't have Bridgestones).
Pedal boxes are something that don't appeal to me. Squeezing the response spectrum of the throttle into the first 1/2 or 2/3 of the whole travel is something I just don't want. It would frustrate me to give it half throttle and know there's nothing beyond 1/2 way.
-
One thing I would like to add for any potential DTUK customers who would be heading over there, south on the A692, from near the Metrocentre, it is all uphill, meaning it is all downhill on the way back. There is a fixed camera on the downhill stretch, on a bit of especially steep part that is a 30mph road. It is very difficult to stay under 30mph when approaching it - so be careful and don't get flashed!

We created a file like you describe but the peak power was less and the rolling road graph looked like a hump back whale..
The feedback from Matt is greatly appreciated as I know how in touch he is with his car so reading this makes me feel proud if what I've achieved..
I'm yet to see any dyno feedback from anyone else on this engine?

Really respect MonkeyHangers unbiased opinion having read his thorough analysis of the GTD in different threads on different subjects. So this has pretty much sold it for me! Once my GTD has been run in I'll be purchasing a stage 2 box asap.
Great work Andrew!

Completely unbiased....just the standard GTI forum discount. :grin:
Yes I have over-analysed my GTD to bits when comparing it to my Scirocco and feeling a bit shortchanged on the performance and mpg front. At one point I was probably competing with Bill for word count on here. :whistle:

I drive that road daily on the way to wallsend. There imo is lots of camera warning signs and even a flashing speed sign road markings before it, has a run upto it after the corner with the chevrons on the road to show were it measures your speed so people should not really get flashed if paying attention. Its also very rare for that one to have film in. That road was far more fun when it was 60mph before they built emanual school there and dropped it to 30mph.
I would rather go back through tanfield village then drop down onto the fellside road for a bit fun on the twistys and abit of sprint on the straights on the way back. Then drop down either swalwell/A1 or whickham/dunston bank/askew road it's slightly less direct but far more fun. Actually I would go the back roads of causey arch to teamvalley but you would need to know the roads for that one.
Nice in depth review of the box.

Took the missus to work this morning. From a cold start, the boxed car is still as smooth as stock with linear response. Filled up on the way back so that I can see how the box affects mpg on a whole tank basis. The MFD looks to be reading somewhere between 15 and 20% optimistic, which is only to be expected, considering the car is putting in more fuel than it thinks it is, at any given press of the throttle pedal.
The MFD range counter doesn't seem fooled though - it appears to be linked to fuel tank contents rather than indicated mpg.

Sorry to sidetrack this thread slightly, but how do you know when your GTD is doing a regen? Also is it not good practice to turn off the engine whilst its doing one?

If you keep an eye on the oil temp while the car is in motion - if it's above 93C for more than a brief spell of hard acceleration then you'll be regenning. If the oil temp is 97-102C then the car is well into a full regen with all the conditions met to make it an effective one. You will notice that if you stop at some lights or at a roundabout then your idling will be up from 800rpm to around a thousand. You might get a whiff of a burning smell if you're stuck in traffic while a regen is going on. If your journey comes to an end and you're in the 97C+ temperature range, then your fan will be kicking in when you switch the engine off, for a good 5 mins or so to cool things down.

Thanks for the great write up on the DTUK offering monkeyhanger. I haven't even got my car yet but am thinking how appealing this addition is :laugh: I'll see how it goes after a few months (I'm changing from an 105bhp Eco diesel so the Power will feel great to me), but it's an amazing upgrade for the money.
How have you been finding it in the days since your review?
Will be interesting to see how your MPG fairs and if you get around the same as stock or otherwise.
-
ffrank: Still going well. Have had a few blasts, but haven't been caning it too hard. 108 miles in from my last fill and the fuel gauge is reading about 1.5 small notches above 3/4 of a tank. I reckon i'll do about 125 miles to 3/4 full and still seem to be headed for 460 miles on the tank (I usually get around 450/460 from the range indicator).
You only need to tickle the throttle to drive it sensibly, with so much more in reserve for when you want to have a bit of fun/hit an empty stretch of road.
Gave it a bit of a hammering coming home from Newcastle tonight on an 8 mile journey and the fan was going when I got home - interrupted regen I think, oil temp was around 93/94 for the last stretch. Oil temp has been behaving as expected pre-box fitment.
-
Sounds immense, thanks :)

Been on an 80 mile round trip today, with most of the journey done at 80mph on dual carriageway. Sat at 80mph, the car's oil temp was between 98 and 102C, which should be ample to keep the DPF clean as a whistle. For quite a bit of the journey I was stuck behind a stubborn Corsa that could maintain 80mph on the downhill stretches, but 70mph on the uphill stretches, and there it remained in the outside lane for about 8 miles. A BMW123D (old shape) was stuck on my back bumper for about 3 miles, I mean liiterally 3 yards off it, I couldn't see any of the BMW below its windscreen, in my rear view mirror.
Got the Devil on my shoulder when the Corsa moved over, because of the BMW trying to sit in my back seats - straight up to 110mph on an uphill stretch, left quite a gap that the BMW was unable to fill. Once I got past the convoy of slow going lorries on the inside lane, I pulled in and dropped back down to 80 and the BMW passed me at about 95mph. Indicated mpg doesn't seem far off what the gauge is saying. I won't know for sure until I fill up, but driving the car generally as I did before adding the box and having a few spirited spurts of box enhanced acceleration doesn't seem to be penalising the mpg.

Not bad at all. The more I hear the better it sounds!

I don't advocate driving like a twit, but for a short spurt, I out-twitted the twit behind me. Not my usual driving style, honest. :rolleyes: The rest of the time, normal driving just feels effortless with the box.
-
Well I finally got through my first tank of fuel with the box on (mainly Jet, topped up with a bit of Esso) to evaluate the box's effect on mpg.
Over 437 miles, the MFD was indicating 47.4mpg for the tank. Actual refill is 46.53L/10.16 Gallons.
So I got an actual 43.0mpg, and the MFD is reading 10% optimistic.
I have consistently been getting around 43mpg actual, from an indicated 44.5mpg over the winter, with the MFD generally being 3% optimistic.
It would seem then that on average, the way i've been driving the car with the box on, the box has been putting 6.8% more fuel than the MFD thinks it is.
So no gains in mpg, but no losses either - and i've had a hell of a lot more fun out of my car as a result of having the box on. The car is just so much more responsive through all of the gears. I haven't had an active regen since fitting the box (save for the car finishing off the regen it was in the middle of when the box was fitted), and the car seems more eager to run at a slightly warmer oil temp, which I assume is helping burn off the collected soot easier for the commute I do.
Best £359 I have spent in a long time.
-
Aren't actual and official mfd figures out by no more than 10% anyway. Read somewhere that anything less than 10% is classed as acceptable by vw so if that's the case your definitely no worse off with the box.

Previous VW's MFD mpg have been out by around 9% (optimistic), My MK7 GTD is around 3% out - they've really closed the reality gap this time around. Definitely the box's extra fuelling that has knocked the accuracy. I expected as much, as I believe that MFD mpg is worked off the amount of fuel that the ECU is telling the common rail to provide, whereas the MFD range and the fuel gauge carry on reading accurately to brim method calculation, indicating they are governed by the fuel sender.
Actual mpg is unchanged (from what we were getting a few weeks ago anyway), so if the warmer weather gains (maybe 3%) have been eaten up by the box, it's a small price to pay for a lot more fun with the car.
-
Am sure it's been covered but how easy is the box to fit ( for an incompetent moron like myself )
It is incredibly easy. There is a plug on the left of the common rail for the injection system, and a plug on the air filter housing for the turbo boost sensor. The wiring loom for the box has 2 ends on it. With the 2 aforementioned plugs undone, one end of each part of the loom plugs into the original VW plugs and the other end plugs into the VW sockets. It is a 2 minute job, maybe 5 mins, depending on how much thought and effort you put into redirecting the wiring loom so you don't need to cable tie it to existing looms. Just pop your bonnet, wait 5 mins to ensure the ECU is powered down (in reality, if you hang around the car after locking up, you will hear the electrics click off after around 90 seconds, 5 mins is an assurance that everything is off). You then pull the engine cover off, it is just held frictionally with 4 or 5 pegs, and do the unplugging and plugging.
The plugs themselves have locking tabs, you just need to hold these in while pulling the plug off its socket, for both sockets.
I will post a pic or 2 of the plugged in system later for you. All the plugs are easily accessible, like VW set it up for tuning! :grin:
-
Excellent, thanks. Hopefully that's not beyond when when the time comes
Actually, you can see some pics I put in the "GTD+" thread when I gave a TDI-tuning box a go. The DTUK box plugs in the exact same way, there's arrows explaining what's what on the pictures. Towards the bottom of page 8 of the GTD+ thread.

Andrew is the GTD dual channel CRDT-2 box the same as the Audi A1 2.0TDI box?
What I'm thinking is my A1 currently has a box with not a lot of gain so if its the same box as the GTD I could order one just now for the A1 and just transfer it to the GTD when it finally comes.
Or whats involved to make the change?

If the sets of plugs on the 2 cars are the same (and they probably are) then the wiring loom will be the same, then it's just a case of getting a software update to replace the A1's maps for the GTDs maps when the time comes.

Andrew is the GTD dual channel CRDT-2 box the same as the Audi A1 2.0TDI box?

First of all I'm surprised your not seeing any decent gains from your current system as these 2.0 143/170/177's respond very well indeed.
A DTUK CRD-T from an A1 can be transferred to the GTD but you would need 2 things.
1) software - this would be free of charge
2) new loom - 2 channel is £50 plus vat

Does the A1 CRDT stage 2 box (185PS from 143PS) not come with the same loom as the CRDT stage 2 box suitable for the GTD?

The first generation of 1.6/2.0/2.7/3.0/4.2 VAG's come with a 3 pin common rail pressure sensor, and a 4 pin boost sensor. The latest 1.6/2.0tdi's have the same 3 pin common rail plug, but the boost sensor plug has changed to a 3 pin configuration.
If you were using a common rail box, then all you'd need is the software update

Its this box http://www.micro-chiptuning.de/Audi/A1/Chiptuning-Box-Audi-A1-20-TDI-105kW-143PS::1568.html and I'm very much of the opinion that you get what you pay for and this cost not a lot :laugh:
Thanks for the info above. Like MH I would have thought they were the same.

I am looking into buying a Mk7 Variant 4Motion here in Sweden, so the promise of uncorking some additional power is tempting indeed. The 2-channel box seems most promising, but I would also like to find a good description of any mechanical differences between the factory 150hp and 184hp versions of the 2.0l EA288. Is it all mapping, or are there other bits that might be worth looking into to optimize the ratio of performance vs. reliability?

I’ve not been able to find anything positive on the web, but larger injectors and turbo are likely on the 184PS version, if not a different fuel pump and possibly uprated clutch (less likely – the torque differences between the 2 variants aren’t huge).
For the previous generation, the 140PS version did have different injectors and a smaller turbo than the 170/177PS variants.
If mapping was the only difference then there’d be no reason I can see why you couldn’t take a 150PS Golf GT right up to 235PS with a dual channel system rather than somewhere around 200PS. 4 motion is going to help your lower end traction a hell of a lot. 7.5s for 0-62mph on a GTD, yet the Quattro equipped A3 equivalent can do it in 6.9s. I’d hazard a guess that an un-modified 4-motion 150PS GT wouldn’t be much slower on the 0-62mph sprint than an unmodified GTD because the GTD will struggle to put down much more than 60% of its output in 1st and 2nd gear.
