He went from 190cc injectors to 370cc injector. His car & your if you still have the TC injectors have to be running rich. Also for everyone's infomation, you cannot put more than 20% larger injectors without tunning. The 370's are 50% more, that too much.

So if your going to eliminate the CEL, don't you have to (1) put the missing O2 sensor back, and (2) put the MAF where it's supposed to be (as in after the filter but before the turbo)? I'm just trying to think back to how the ZPI kit was built... Isn't the MAF in it's stock location, trying to measure pressurized air flow? I can't remember...

Oh, and congrats on the turbo. I'm jealous but must admit I was skeptical based on the sellers history.

Yeah, I've offered to test fit some RC Engineering injectors in my motor to see if they'll fit. According to my calculations, 270 to 300 cc would be the max we can put into the Yaris and still expect the stock ECU to be able to control at idle.
