i am not sure which one this should be in here or electrics but here goes. I have had a quick search but nothing came up. I have a rev 2 turbo and i want to get rid of the afm and i have heard that some people on here use the rev 3 ecu a map sensor and a ait sensor, but i am just wondering how i do this. If anyone has any info plz could you tell me what you know or how i could find out how to do this. It involves replcaing the ECU and fitting Rev3 injectors, ait sensor, MAT sensor, ignitor and MAP sensor. These are all fairly easy. You then have to change some wireing to the ECU. This can be tricky but if you take your time is easy to do. If your interested i have the injectors/Rev3 MAP sensor,ignitor, MAT sensor and air intake sensor for sale. There has been some interest in the parts but nobody has commited to buy yet. If your interested please PM me....2Crooky wrote:Just to warn you a lot of people encounter problems when doing this conversion and have actually lost power if it is not done correctly.
...nothing was wrong with the way others and my car was setup or installed...rev3 ecu just doesnt run right for numerous reasons.....mainly above 6k rpm....tho mine had a massive power drop after 5k rpm, lol.........less of a conversion needed.

...and nick was running a huge ct26 hybrid which could of helped matters....and ROGUE of all places and i still had issues........ just last weekend infact! 
... For example, I posted a query in the 'electrical' forum a fortnight ago and haven't had any replies 
There seems to be a TPS change too that I have never seen anyone make reference to and I don't know how critical this is. Sometimes I think I'm going backwards rather than forwards! 
Youll get a lot more help then. I dont think many people look in the electrical secsion and what your doing is a mod. or should i just leave it alone? Does the afm restrict my power and if so what to? I just want to prove people wrong because i have the gt4 185 and people are telling me it cant be done for the power i want, about 450 500 ish hopefully. I have just done a search on this, and now i am more confused on what i have to do and y they dont work, and what i have to disconect. cos i have read so much now i am just confused. ](./images/smilies/eusa_wall.gif "Brick wall"){kind=small}
i click on links and they dont work anymore I want to run the emanage aswell. I am a mechanic so doing it isnt a problem i am just confused.(am I right here?) as there is better information about it available then the MR2 rev2 to rev3 swap. I have some notes I have made about the UK spec ST205 ecu loom that may help and I can send them to you if you pm me your e-mail address. i have tried lookin on the gt4oc and there is less info on there and somone told me to look on here, most people on there only think about motecs and stuff and say it cant be done without a standalone. Cheers ill send u a pm,sensors etc off a rev3 turbo,it must be ok as i run a 12.158-1/4mile in the car.Had the looms off gtschris and at a good price.Paul I am just goin to swap the pins about for the ecu and ill have to re wire for the new sensors. What did you do with the TVIS? How long did it take you to do the conversion? paul t wrote:I did the rev2 to a rev3 ecu conversion on my car last year i just used the looms off a rev3, and i have not had a problem with my car going up to the red line and i am still running rev2 cams only thing i am using is a turbo

How much NOS are you using to get 12.1 1/4 mile
