so on monday my car was broken into outside my house and they took my subs and my ecu. i couldn't find any d16a6 ecus at junkyards so i bought an integra obd-0 ecu. it runs really good suprisingly. the problem is that i pulled up to talk to a guy about his crx and he noticed the CEL popped up for fuel supply system . i must have sat there for maybe 5 minutes tops. is this a major problem? thanks for the help guys

 

what model is the ecu

 

im not positive on it its like pm4 or pr4 or something like that. its an 1991 integra ls ecu. can it be that its pumping out fuel for a 1.8 into a 1.6 motor so im running rich?

 

if it runs good it should be fine. maybe a little different fuel maps but the readings from all your sensors should take care of that. do a little searching and you'll probably find the info you need


thew ecu will say what model it is near the serial number.

 

yea i looked at it rite before i put it in and its raining now so i didnt feel like leaving to check it. i was thinking to flash it with turboedit for the proper fuel. i know how to use uberdata so i wonder if turboedit is basically the same concept

 

im sure you can find plenty of pm6 ecu's on here for cheap, probably less than 50 shipped

that way you wouldnt have to program anything and youd be back to where you were

 

i gotcha i also have a p28 chipped that suppose to go in as soon as i turbo so maybe i should just obd1 convert it b/c i have no more money after gettin broken in to. thanks for the help man i appreciate it

 

if you have an a6 block and head i would run a pm6, unless you have a mini-me(z6 or y8 head/a6 block) then run the p28. but i think it is better and much easier to run pm6 with turbo a6

 

i think its the ecu in the 88-89 integra with the d16a1 that people use instead of pm6s. they're 1.6 also but have moe aggressive fuel maps.
if you want. i have a spare ecu that was never chipped or even opened. pm me if you want it.

 

so the integra ecu wont really mess anything up or it definitely will?

 

It runs a whole lot richer then even the 88/89 integ ecu i found out. One of my friends had it in his hatch, and in some cases it can make you'r car run like ****.

 

my car ran like **** with the pr4, too rich for my taste

 

it runs like hell for a couple of bloack , throws the CEL. when i reset it it runs good. i dunno wat to do now. also would the weather affect it? its rainin rite now in philly

 

I wouldn't think the weather would effect it, but i rather have a Pm6 or pm7, "88-91 si ecu" or another words "pm7 ZC legit ecu" in my car then the Pr4. Plus you'r rev limit isn't any higher then the pm6 i don't think, somewhere round 6800-7100?.

 

the rev limit is abouyt 7100...i had a pg7 in my crx.. never tried a pr4....jus go with a stock pm6 or 88-89 integra ls ecu (pg7)......
