hey guys, ive got a 97-01 prelude type S engine obd2 ecu, and gonna be buying an obd1 ecu so i can chip it with hondata.. ive been reading a lot and apparently the most suitable obd1 ecu for my engine is P72 that i can chip with hondata s100... but isnt that a gsr ecu? just wanna get some input from some honda nuts before i pull the trigger on a purchase. thanks guys.

 

i believe there is a write up in the faq about ecu's for ludes. yes a p72 is for a gsr but from what i remember it isnt optimal for an h22. the good thing is that it is programmed for the butterflies that both the h22 and b18c's have. but with hondata they should be able reprogram it to match fuel curves and ratios. a p13 would suffice as well. since its a h22 ecu. p28's are able to be used as well.

 

thanks bro (y)
