Herbie As you are aware, I originally sent to you an Apexi ECU which you purchased as a 'supply and map' package. At no extra cost, this was supplied complete with a map I compiled and loaded to suit your set up for running in purposes. The aim here being to save you a double trip down to see me and basically save you some money. I realise however that you are still smarting from me not offering you a refund on the final mapping session you had already paid for as part of this package....... but then failed to turn up for.... twice ! I personally think it was a bit of a cheek to ask for a part refund after completely wasting 2 separate half days of my time by not turning up for a pre booked mapping, even if you did have the best excuse yet......... that you were in Jail !!! The final mapping was subsequently completed here as per your original request, even if you had taken it to your mate previously and had him do a 'part' job on it. You seemed more than pleased at the time, especially when I explained in detail how I was giving you a much safer set up than you arrived with. I'd like to think I don't intimidate anyone here nor do I think I "dictate this forum" whatever you may mean by that ?? Please feel free to post up on here anyone that has felt that way. You may want your "far superior person" to finish off answering my technical challenge to him on the other forum regards the tuning of your car on a rolling road. I think he wanted to put the topic to bed but if you really want to dig it up again.......... cheers Andy

And how cool would it be if it was also reliable enough to compete more than once a year [] ..... meeeeaaaooowww []

I've just thought of an excellent way to save an absolute fortune modding my car. I'll just post up some power graphs from the race car, pretending they are from my new age car and i will be 'the best' [] Why not ? I'm happy with the way it drives with 300bhp, all thats missing is the huge bhp dyno sheet to lay on the dash at meets and for chatting about on-line [] Only one flaw in that plan, I can't remember the last time the race car was on a dyno......

Tranent, 5 mins from me.

I ran octane booster for over 400 on my set up, Harvey has just made 420bhp on a 20g on his car, not sure what fuel mix that was on ? GT hybrids should be able to do it on V power.

So you did [] and thanks for the beer []

If you want to guarantee 400+ then I'd say the Garrett hybrid but be carefull which one you get, the 20G has made more than 400 but not on all applications. Andy

Nice result Peter [] Andy

FWIW, an unmetered air ingress prior to the turbo would not necessarily show itself during mapping IF the leak was consistant throughout. The mapping process includes matching the fueling to the measured airflow, there is no way to identify a smallish leak as the maf signal is different on each car. If the leak stayed constant, then the performance would not be affected up or down (other than unfiltered air causing more wear over time) The problem would come when the leak either increased or was repaired. If it increased then the car would run lean and possibly over advanced on timing. If it was repaired/reduced then it would run richer and with more retarded timing. If the air leak was post turbo then the opposite would apply. Andy

And I have one I could be talked into selling !

I used to have an RS1600 BDA with steel internals, cams etc running on 48's much more fun than a scoob, sounded brilliant too ! Regards tuning for power, I can tell from the air and fuel flow in conjunction with the ignition timing if things are improving or not. Measuring the acceleration between two fixed rpm points also provides useful feedback. The resulting power 'number' is just a consequence of getting the best from the parts fitted to the car, thats all I aim to do rather than target a particular power figure.

I'm not claiming any figures whatsoever for Chris's car, anyone that has had their car mapped here will vouch for that. I'm just saying it made more power on the td06-49 turbo than the previous unit. Raising the fuel pressure can allow the injectors to run more power, I've seen as high as 440 bhp from 550's at 4 bar diff

Point taken JC (your next remap has just gone up [] )

"a standard engine will only flow so much air...doesnt matter what size of turbo is trying to ram the air thru it... fundementals my good man LOL" Wrong I'm afraid. A std engine can make extremely high bhp with a big turbo, longevity is the issue. A std internals 2.0 Sti 7/8/9 on a big turbo/intercooler/injectors will flow enough air to run to 500bhp (for a very short time) Gumballs car was making more power on the bigger turbo without doubt. As an example at 1.5 bar a td04 turbo will run 290bhp, TD05 will run 340 and a TD06 will run approx 400, A twisted GT30 would be low/mid 400's ..... on the same engine. Andy

If you want to leave it with an 'Andy' Jamie, then I'll volunteer [] The other Andy tends to be .... er a little bit unlucky and breaks his toys on occassion [] Andy

Scott I have given up trying to educate both you and your tuner Steve Simpson. I explained to you a number of times that with the APS parts fitted your car was suffering from boost creep, a mechanical issue with the turbo that is outwith the control of the ECU, any ECU. Any tuner relying on an AFR figure as displayed on a rolling road on a car with a maf sensor and induction kit has a basic lack of understanding of how these cars work. See you at knockhill shortly ? I'll also have a new age car so level playing field [] Seems like someone is going to have their mirrors full of blue and white eh Craig []

Still got some way to go to catch this 3.3 flat 6 puppy though !

Thats news to me Scott ? When you melted your exhaust headers (due to high EGT one assumes) and had your engine problems you were on the GEMS ECU or did you forget that ? Andy

Kev has done a bit of work to the car since I sold it, FMIC, 20G instead of 18G, TGV delete, cold air induction, 3" instead of 2.5" exh, all topped off with the ECU's 53rd, 54th and 55th remap on sat night !! Still on the std clutch ! Andy

In my defence, I only ran it with the 18G on ........ your honour []

It would be impossible on 380's ! The car has 650cc injectors fitted Kev. If you had known that would you have paid me more for my baby Andy (Creator of Project WRX)

Yes it was, you just missed each other. That was a car you should have had a run in Craig, severe traction issues 2nd and 3rd []

If it was TOTB3 then it is the same car I have now (well the bodyshell anyway !) The Blue Sti 5 ran in TOTB 3, 4 and 5 My previous White WRX RA was at TOTB 2 Andy
