The PP is a piggyback, right? Does it have control over the engine at all times or does it jump in to change parameters when passed a certain condition? Example, the UTEC on WRX/STi's isn't always in control. It takes control once you reach a certain load point (boost+RPM) which is usually right whe...

Tom, You can't use the stock legacy ECU and expect to run all that stuff how it runs on the STi. It just won't work. The sensors may be able to handle the parameters that the STi puts out, ie air flow, fuel flow, etc. But the ECU has the maps and stuff to identify what a particular voltage means an...

anyone?

is perfect power able to control timing as well?

but the USDM STi MAF does work with the legacy ECU? I'm more or less looking to create the parameters of what the stock USDM STi creates. VF39 14-15psi boost, STi injectors, STi MAF, fuel pump, STi TMIC , and source out fuel rails from a 92-94 N/A to mount the injectors. And from all this hopefully ...

Hey all, just wondering if it is possible to swap in the USDM STi MAF into the EJ22t. I have some spare stock 04 STi parts off of my own car and was thinking about using them. STi injectors, VF39, fuel pump. I doubt it but was hoping to basically just make a legacy run with STi parts without having ...
