is anyone surrently using a jdm p72 obd1 ecu for their gsr? i know there is a speed limiter on them but i heard they have a more aggressive fuel system. would a USDM p72 obd1 be better? wat r the pros and cons of the two, b/c i just purchased a JDM ecu and just wanted to know the major differences and i f i should've gotten a USDM p72 instead.....

 

guess nobody in HT knkows.............

 

I'm not positive, but I think the fuel map of the JDM p72 is richer than the USDM one. I don't really see much of an advantage to it, but if you got it for a good price, then that's great. I suppose either is good as long as it's OBDI because it'll allow you to use things like Hondata to tune.
