Im putting a b18c5 (OBD2) into a 93 civic and was wondering which ECU to use the motor will be rewired so i can use OBD 1 but they dont have a TYPE R OBD1 ECU so im thinking either p28 reromed or just p72 or is there another way thats better. I dont have all that $$$ so i cant go customed ECU any answers will be great thanks

 

I ran a JDM ITR P73 ECU with a jumper harness. It was an OBDI program, but it had the OBDII plugs - go figure.

Then I put a Kenji-done P28 ECU in and ditched the jumper harness. The motor felt as though it made more power after switching to the P28. Now my ****-JDM speed limiter is gone, and my VTEC hits at 5800, and my rev limiter is set at 9400 for when I drop them lumpy bumpsticks in later on in life!

BTW: the power figures were pretty nice with the P28: 175whp 122 torque! No tuning at all. Those are impressive figures for a STOCK ITR motor with only intake and exhaust.

 

thanks for the info i tried out my friends p72 then put the p28 in man that p28 pulls hard thanks for the help
