Golf Mk3 1.8T Audi S3 AMK engine k04-023[/b] R-Tech Custom Remap session-v1 270bhp 275lbft MAF flow 219gs @ 1.2bar



2005 Mk5 GTI 2.0TFSI 197bhp R-Tech Custom Rolling Road Remap session.



Stock power made 206bhp 234lbft for some reason the car made high stock torque output, it should be around 205lbft?
So we carried out a full data logging session to find out why the torque was so high on a stock power run.  Our findings where that the N75 boost controller was a little lazy and was reacting slow, causing the boost to over shoot  and the ecu pid controllers react to late.

 

Next step was to take all the logged data and produce a spec1 base map based on the compiled data.






During logging and loaded power runs we found a major flat spot at 5000rpm, which also can be seen in the stock map so the remap has brought the issues to light.  We made another 4 map version to try and iron out the issue, but only made the flat spot worse, as this point we put the flat spot down to hardware.   After looking at the logs we found the air flow to increase at and N75 effort get higher at 5000rpm without and gains in the power curve which mean the issue is boost / air realted. After 20mins of hardware testing we found the one way PCV check valve to be leaking and sticking open...end of mapping session.  New part on order.

final result today= 237bhp 278lbft with PCV issues.





Just goes to show mapping is only 50% of getting good power.. the rest is down to the tuner to id hardware issues.

26th July 2011 Job number 1
Stock mapped 2005 Audi A3 2.0TDI 140pd with 88k which has had sticky VNT for 3 months and only went into limp mode 5 times.
End result was melted turbine wheel tips and melted VNT vanes which has resulted in the turbo being a door stop.

If your running a TDI 1.9TDI or 2.0Tdi no matter what year then get your VNT checked. The turbo can over boost to 40psi and hold 35psi without you knowing, the only time the car will show a fault code is when the ecu sees 400mb of over boost of 10seconds or more in one stint which is when the ecu cut the fuel, BUT the car will still be over boosting.
We are now doing around 7 VNT turbo repairs each week, I would say 5 out of 10 TDis
 with over 60k will suffer from sticky VNT and will have 17965 - Charge Pressure Control: Positive Deviation

We have opened a new two workshop bays just for VNT cleaning and DPF issues cleaning and removal

Golf AUM 1.8T 20v ko3s (not same car on all 3 runs)

Stock Mapping  = Stock filter & oem DV - 95 fuel = 156bhp/163lbft
R-Tech Spec1 =  007p with yellow spring - Pipercross filter - V-power = 209bhp/234lbft
R-Tech Spec2 =  007p with yellow spring -Cold air induction kit - TIP- THS front mount intercooler - Milltek Turbo Back = 231bhp/259lbft

Spec2 mapping allowing for extra mid range boost without running the risk of too much heat build up, 21psi peak and 18psi held with VE tail off, which gives close on to 100lbft gain from stock in the midrange and holds  on to it really well, without too much heat build or fuel dumping.

How come there is less transmission loss on a AUM than a AGU?

AUM spec2 231 bhp @ Fly - 208 @ Wheels
AGU KO3s  231bhp @ Fly - 200 @ Wheels

There is not one fixed rate for drive train losses, wheel weight, wheel size, tyres, brake discs, bearings & temps, gear box fluids, diff and transmission condition, strapping down on to the rolling road ect..  Some rolling road like the dyno dynamics just add a fixed % to the wheel power, which is give a false reading for the engine power because there dyno cannot see the drag factors during the run.  I can get the same result for the flywheel power even if I apply the brakes during the whole dyno run and the coast down.

Would it be strange though if myself and a fellow AGU K03s user both produce 231bhp and both get 200 at wheel? Both on 18 inch wheels

One car could push 200whp and 230fwhp and the other 197bhp and another 230whp or even 205whp and 230fwhp

More drag = less wheel power on a Dyno Dynamics rolling road you will get a low fly wheel power full stop. On our rolling road we can work out the exact drag during the run which is added to the whp as a factor not a estimate or calculated %.   Rule of thumb is 15% for fwd transmission losses so 200whp works out around 230 hp at the fly and 22% for a rear wheel drive car which work out about right for the C20let Kadet we ran at 330whp & 399 hp at the fly.

Two brand new cars just out of the factory should give the exact same whp losses and fly hp, but if you change  one cars tyres, fill them with less air and use thicker gear box oil ect the drag will differ so the power at the tyre contact will differ but with the losses added (from the coat down run) the flywheel power will be about the same.


I can run a car will cold tyres, cold gear box and diff, cold transmission fluid, cold bearing ect and get lets say 250bhp at the fly, then run the same car with hot gear box, tyres bearing ect... and still get 250bhp. BUT the output would look like this:
Cold run = 220 wheel hp with 30bhp drag losses = 250bhp at the fly
Hot Run = 223 wheel hp with 27bhp drag losses = 250bhp at the fly

How has hulmie got 231 bhp with only ko3s, and those mods listed in his sig ? was this done at r tech ?
 
how accurate are the rollers, how oftern are they calibrated? ill be getting my AMK lump done very soon and you are on my shortlist for a custom map

undicided how hulmies car can be 231bhp with just those mods 

[string69]

mines on a ko3s and made 242bhp @ r-tech  simular set up sports cat not decat.

[F17BAD]

nah man, not having that at all

245 with a ko3s and a decat WTF ??

Rtech what rollers do you have and when were they calibrated ?  bet mine would be about 300 hp going by these results 

sports cat isnt gonna do fack all really tbh, iv got one but im running with no cat at all and iv got all the mods hulmie has but only iv got a K04 (Audi S3 engine)

Our rollers are bang on the money.. We have 2 rolling roads down here and both read around 1bhp-/+ within each other. And back to back with JKMs rolling road again about .5bhp-/+   Other rolling roads such as awesomes dynojet reads much higher than our dyno, again proven by golfgtiforum members .

Proven on many rolling road days, and proven on the 19th June with Len passat made around near enough the exact same power aw what he did on JKM dyno a few weeks back.  Then the same about 2 years back when Rhyso and Adams cars made near enough exact same power on our dyno v JKMs, when people where saying there car where know where near the torque I quoted..lol I think on both car there where 4lbft +/-.

I like to know my dyno is about bang on all the time, becuase I would look a cock when customers car go to another rolling road day.


And as for k04-023 they dont make know where near the peak power everyone quotes, with them its all about the midrange the realistic peak power is 270bhp TOPS with oem manifold, which I managed to do and a nother tuner on seatcupra.net / audisport.net was quoted on saying its one of the strongest and best running k04-023 he has see running on his dyno backed up with outstanding MAF logs. 

See what the k04 boys are getting http://www.jkm.org.uk/performance/GallerySCN280309.htm
