hey all i just bought a d15b non vtec and converted it to mpfi and i was wondering if a pr4 computer would work in it,,, if so how good?... if not pr4 what would be a good choice.... thanks

 

anyone???

 

i belive a pr4 is a b16 ecu if u ever plan on vtec get a p28

 

i got the pr4 out of an integra.. but i think ill just run a pm6

 

P28 is even better

 

you guys prob just confused the **** out of him.


ECU's that will work
obd0 pr4
pm6 (best)
pm7
88-89 pg7

 

thanks racintweek..... and i knew what they were talkin about.... but i thought that p28 was a vtec comp???

 

p28 is obd-1, have you converted. pr4 is the ls computer. it will start it up and run it but i dont know how good. si or zc would be what you want if you are obd-0

 

a pr4 is off an ls motor! no vtec on it i think it would be a great ecu for the more~

 

what year ls 88-91

 

I just bought a 90 si with a d16y7, and it came with a pr4 ecu in it. The engine felt like it had no *****, and it redlined at 6000?!?!?! I threw a stock pm6 ecu back in and it made a night and day difference and the 6000 redline was lifted; anybody care to explain what could have caused this?

 

just get the PM6 or PG7 they will both work a hell of alot better than the PR4, which is for a DOHC NON-Vtec 1.8L

 

Which engine/car is a pg7 originally from?

pg7 = 86-89 usdm integra.your motor will run rich with the pr4 ecu.
