3rd Gen 3SGTE Stock ECUvs MR2 EECU, had a talk with a guy today. Options

Hey everyone,

so in Dire need of a flywheel, fate decided to get me in touch with a All Trac owner who had an extra flywheel. he has put in a 3rd Gen 3sgte in his all trac and loves the hell out of it. he was telling me though that I should be getting a CEL because of the ECU not seeing the water pimp for the intercooler... and this would bog down the system and the car would lacking in performance. he also stated that because he bought a 3rd gen MR2 edu his boost leveled out at about 18PSI (now is 22PSI)

I DO only get 12-14 PSI from my Turbo, but I don't have a CEL. never did, I don't know if thats because I routed the waterpump to just come on when the car power came on or the Wiring Harness Tweak'd did.

has anyone else heard of this before? I'm curious to know. he did offer to put the MR2 ECU in my car to show me the differance (which I intend to do when I get my car back and put in a new flywheel and clutch)

Thanks
Kevin

I am running a stock ST205 ECU.

however, the guy who I talked to has an MR2 Stock ecu in his. he has a Boost controller so that's, (assuming here) how he is managing the 22PSI I believe.

he told me that the ST205 ECU, if it can't find the water pump in the system, it will bog down the performance of the car, only letting it boost around 12-14PSI. while the MR2 (not having the pump) ECU will allow you to boost to the 'stock' 17-18 PSI. though it comes with a -10 HP cost.

if this is the case, I'll probably will be switching out the ECU soon-ish. if no one else here can confirm this then I will probably take him up on his offer to put his ecu in my car. and Ill test it...
