Right so i've decided to go with Revo as they offer a nice 55bhp increase for £587 and i've got 2 franchised revo dealers near by who can do it.
The problem is neither of them have rolling road facilities. After speaking to both of them its clear that all they do is hook a laptop up to the car, update the ECU and then hand the car back to me.
1. How do they know its 255bhp after the remap if all they do is update the ECU?
2. How do they know what boost, fuel etc timings to use for my car?
3. Are Revo maps generic?
4. Who am i?
-
I wouldn't part with that much cash without a before and after run on the rollers.

Stage 1 is generic and is tested to death with various test vehicles both on the road and using a rolling road.
255bhp is probably the biggest gain you can expect.
As Nick says though i wouldn't part with such a large amount of money if i couldn't verify what i was getting
-
A big NO NO to that. I'd rather drive somewhere further and know what I am getting. The fact that these people haven't got rolling roads but are offering remaps doesn't instill much confidence. :huh:

ye thats what i thought. But still Revo allow them which is a bit strange really. The nearest dealer with rolling road is in Halifax, 90 miles away, called The Racing Line

yebut think of the fun you'll have driving back :cool: plus it will give your GTI an ample opportunity to learn the new software :afro:

And Halifax is loverlee this time of year! :wink:

Rolling road is a must. It is okay for someone to say that you are going to get 255bhp, but where does it sit in the rev range? what torque will you be getting and where in the range is the most useful torque sitting. You can tell all this and more by having your car rolling roaded after the map and looking at the printout. Just as importantly though, if you have the car rolling roaded before you will know if the engine was healthy before the remap too. For example, if you went to have your car remapped somewhere without an RR then how do you know your car was pushing 200bhp in the first place? It may have some fault in the engine, ecu, hoses, DV etc reducing the standard output and you wouldn't know it!

for anyone interested in revo switchable look at this

Revo are good and they were one of the options I considered. After thinking about it though, I decided on the APR system as it does away with messing about with the OBD port all the time. :wink:
-
How do you find the APR re map? Consumption? Power? Flexibility? anything else I may have missed? Also what was the additional cost on your insurance premium?

I'm still getting used to the remap but find that it is useable and doesn't deliver in one big slab of torque like some remaps I have had. Flexibility is excellent and when used in manual mode it means that I can select an equivalent higher gear when cruising and so economy should be better (although I haven't measured it yet). Insurance premium went up £75, but I have full no claims, no points on my licence and am "over 40".

A rolling road isn't always necessary to re-map a car.
I used to get my Impreza live mapped on the road by Andy Forrest www.andyforrestperformance.co.uk (http://www.andyforrestperformance.co.uk) who has long argued that although a rolling road does have a place when mapping a car it cannot completely re-create real world conditions, all it can do is try to simulate them but this isn't without some considerable room for error, the rolling road operator can also do things to manipulate the results to make you think you are getting the results you've paid for and want to see. Although some of it is specific to Imprezas it highlights some of the issues with rolling roads http://www.andyforrestperformance.co.uk/26063.html

Umm... you're assuimg that Maximus's local Revo guy will actually take the car out on the road when remapping. From reading Maximus's post, this doesn't seem to be the case. If they do, then I reckon its better than a rolling road.
-
I would say road mapping was better too. Something else i noticed is that there's no mention of monitoring AFR, how can you do a proper re-map and not look at whats coming out the back?
When i was getting my car done on the road, it had a wideband AFR probe in the exhaust and a knock detection headset, basically a very sensitive microphone bolted to the engine.
We would then do various load runs from x to y rpm in different gears so that every load site in the ecu is used and can therefore be adjusted accordingly. By knowing whats coming out the back you know if the engine is actually able to burn the extra fuel your putting in, otherwise you could easily loose power! Then by listening to the engine you are able to tell how much ignition it's happy to run.
Not monitiorring any of these things seems like a bit of a half job to me :huh: either that or it's a very conservative tweak and is by no means a custom map.
