I have a '92 civic hatch si, in the car am running a '99 gsr engine. But still
running a single cam ecu, but it is chiped. Now am asking because a lot of problems have been occuring with my V-tech first code 41, and just last week code 22 which is v-tech presssure valve. Is the ecu the problem, PLEASE HELP.

 

first off you'll get a lot of crap since it's v-tec, v-tech makes phones. but if you wanna keep the car obd2, then you can run 96-2001 p72

 

if you are using a chipped p28 in your civic si then what you should use for your swap is a 1994-95 gsr p72 ecu. you will still need to wire in IAB and KNOCK SENSOR to make all the cels clear.

i have a 1995 gsr p72 for sale. good luck

 

but which one works better, and will it just hook on like the p28.

 

what intake manifold are you running?? if stock you will want to run p72 obd1 from 94-95 but you have skunk2 or different you would want to run chipped p28 there are plenty of diff. programs you can buy according to your mods
