I'm curious what, if any, effects running a P2T ECU from a '00 Civic Si on a Ek hatch with a '00 GSR motor in it will have?

They have pretty close outputs as far as hp/tq... give or take 10-15.

Do Si's have smaller injectors? Will the Si ECU pulse my larger (if they even are) injectors adequately for proper fuel mixtures? What about the displacement issue (1.6L vs. 1.8L).

Sorry for my very limitted knowledge of Honda ECUs.. the car is running well with this setup, but I don't want to end up running lean and burning valves or such... I can't use a OBD2 GSR ECU because of the immobilizer.

I'm buying this car and driving it back 1000 miles. If I'm in danger of running lean while I'll be cruising for long periods of time (hours), I want to take care of it.

Thanks!!!!

 

The P2T ecu doesnt work the IAB of the gsr motor. I wouldn't recomend it.

 

I would search on Ht for a 99 GSR ecu. They dont have the immobilizer.

What's IAB? Butterflies? I heard the car running, and the guy who did the swap last weekend says it runs great... only CEL is for the 2nd 02 because of the test pipe.

What symptoms would I see with no IAB control?

Is a 99GSR ECU a P72?

Since I'm running a '00 DX wiring harness (with VTEC wires added), it should already have knock sensor wired, right? It's the same pin on a P2T as it would be on a P72?

Thanks!
