List,

I need some info on how to put a cosmo 13BRE(W) twin turbo motor TPS into a S4 ecu. Currently looks like the previous owner has jimmy rigged a stock TPS into the UIM and rigged it into the car. RIght now the car seems to be running really rich.

I have attached a poor picture of it. But if anyone has pictures or anything to share that would be great.

In fact a diagram of the twin turbo would help as well for wastegate boost control hookup.

Thanks,
Ian

 

The S4 ECU needs the VERY simple S4 TPS. It's basically a switch - tells the ECU when the throttle is closed, and when you're at about 20% throttle.

The FD and probably the Cosmo use a full-range TPS, which won't tell the ECU what it needs to know.

If you're running a Cosmo engine, the stock ECU has no business being in there. You need some sort of aftermarket fuel injection system - Microtech, Haltech, etc.

I understand the importance of a full standalone. That is out of the question due to cost. It is getting a Haltech F5.

Thanks for your help.
