So i tow my car to our local shop to have some work done to it. Turns out it will cost way too much money so I have it towed back. When i left the car i had my JDM PR3 ecu under the seat. When I get the car back i take a look at the ecu and it says PR5. What the hell is a pr5 ecu? they are saying they didnt do it but I dont think a PR3 ecu could magically turn into a pr5. I think it is a 88-91 zc ecu but not sure. anybody know?

 

its a sohc zc ecu, i believe its a jdm ecu

 

i believe the PR5 is for the 88-91 B18A LS teg.. it has no rev limiter.

not sure why they would swap it.. but either way, i would take that back and try to get the original ecu.. why? because its yours....

but good luck trying to prove they swapped ecus

 

pr5 does hav a rev limiter its at 7000 i got that one in my car

 

SOHC ZC??? I need one of those haha. I need a REAL SOHC ZC ecu, not the D16A6 ****.

 

oops my bad

ludesrv.. what engine do you have? in my d16a6 i used an 89 integra ecu.. it was really nice, and you could definently feel the difference from the si ecu

 

a little off topic but where is the ecu located on a 88-89 integra? i looked in the kick pan but it wasnt there. perhaps under the seat/glovebox? also does it clip right into my 90 si harness? sorry to hijack the thread

 

^^^^I believe 88-89 integra ecu is under the seat, remember seeing one like that at a junkyard.

 

not sure.. if its like the 00 itr.. its on the right side of the panel, next to your feet. you have to the cover off it

 

dont mean to jack this thread but..i have a jdm d16a (which i guess is the sohc zc) i was told a p28 is best for this motor..what do you guys think?
