ITR ecu problem
My roommate has a 92 CX that we put a 98 JDM ITR swap into. He got the swap from Hondamotors Online and they gave him a 92-95 P30 ecu from a sir2. The car does seem like its as fast as it should be. Wouldn't the P30 ecu only supply enought fuel from a 170hp b16 and not enough for a 210hp jdm itr let alone the proper timing? He was told that the P30 has the same fuel/timing map as a ITR but I don't see how thats possiable if they both use 240cc injectors and the 2 motors make 40 hp different. Where can we get a stock itr program chipped into the P30?

Re: ITR ecu problem (hybrid901)
the reason the motor has 40 more hp is because its .2l bigger and has more agressive cams.
dont worry steve is a good guy, let the motor break in a little and see what it feels like. as for the same program, im not sure. they have the same head (basically) and injectors so i dont see that there would be TOO much of a diffrence

Re: ITR ecu problem (KAMiN)
The ITR motor also backfires inbetween shifts when on the throttle hard. Since it does this, it leads me to believe I am running lean because the p30's fuel map is not correct for the ITR. Can anyone verify this? Is the p30s fuel map supplying enough fuel?

Re: ITR ecu problem (hybrid901)
you're right no there is not enough fuel from P30, it does tend to run rather lean on the ITR, there are few fixes:
chip it or get a adjustable fuel pressure regulator or VAFC
closest thing to an ITR maps is Spoon program, which will allow you to rev a little higher
also on the topic of ITR the JDM version only makes 198hp (200ps) regardless of the specs (96 or 98SpecR)
