I am comming up to Seattle this weekend, and I will be here through Valentine's Day for business, and then hang out with some family. I have a TurboXs Uni-chip ECU engunemanagment. Right now it is set for stage 2 or 2.5. I think the only difference for 2.5 is the downpipe, which is what I had. Anyways you can check the specs on it at www.turboxs.com . It comes with the TurbXs MBC too. The ECU is great, but I am getting rid of it cause I have no WRX anymore. Got an STI now, so if you are interested you can email me at Cwrinkles75@yahoo.com or you can pm me. I am askin $450 obo

 

You do know that the STi is a WRX, right? And that they're both Imprezas?

 

Um... yes I do, but that doesn't mean that the Engine Management is the same! It's mapped differently. I am sure the ECU wiring diagram is different too. If I put this ECU in the STI, I will prob get less fuel then I do stock. I don't think the Utecs and Unichips from WRXs work for STIs. Remeber a while back, when everyones STIs were stock, cause you put an exhaust on and it would cause it to ping, and detonate. There were no engine managemenets available. If the WRX one works on the STI, then why didn't people use them then? Hmm... the world may never know!
