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?

 

well the fuel/timing maps of a stock P30 vs. a stock P73 ecu aren't super different, but yes it is true that the P30 ecu is mapped for a 1.6L engine and it would be a little better to upgrade to a 1.8L program or ecu.

Now, the slutty mugen program is one program you should look into. It works great for 1.6 to 2.0L vtec engines. Although gas mileage is lost, its a great power making program (once you go dyno and finely tune with a vtec/fuel controller). I've seen gains of 5-8hp made with this program on 1.8L engines. This program will work on a P30 ecu also.
I'm not trying to give a sales pitch even though it sounds like it, but you i offer reprogramming services if needed.
