I'm using the s300 in a p06(92-95 civic dx non-vtec)ecu, in my 00 civic si(b16), i'm having trouble with the iac valve working, i checked the wire from the iac to the ecu harness, had no bracks in it and with the stock (p2t)ecu in, it works fine. If anyone has had this problem or any tips please help.

My best gues is that your ECU mught have a problem and nt the S300. I have tuned several cars with that problem and it was solved by replacing the ECU.

would the p06 be the wrong ecu for my car, hondata doesn't list it under search by vehicle, wasn't sure cause i bought it from a Hondata dealer with the s300 all ready installed so i didn't think he would have sold me the wrong one

A po6 is a non-vtec ecu unless someone has modified it. IAC is the same on all ecus.

vtec will engauge, another dealer thinks its a bad ecu but i don't have another car to test in. I tested the voltage at the iac and got 2.77v at the blue/black wire (runs to ecu) and 13v at the yellow/black wire while the car was running, and on a 94 integra i got .09v-.11v at the blue/black wire to ecu that vary by thr. were mine didn't.

bad ecu, we swapped with a good p28 light gone and iac working properly, thanks
