[bmx4life54321]

hey guys i have a b18b1 swap in my civic coupe. its an obd2a computer and saw somewhere that switching to an obd1 computer with basemap adds about 15 hp. what im wondering is that would putting a basemap in my computer i have now be just as good what is the difference and pro's and cons?? thanks guys

to my knowledge you cant tune OBDII computers, which means you can't put basemaps on them, thats why many people switch to and OBDI ecu. if you're interested in switching, im selling a virgin P28 ECU with a jumper harness.

isn't the p28 a vtec ecu?i dont have vtec. if it will work than yea for sure since the cheapest good computer i found was $150 and a jumper harness is $75 i really want a computer i can tune.
