I bought a JDM D15B motor for my 1990 DX hatch and I was wondering I have an 89 Integra PG7 ECU and I want to run it with the engine. The engine has injectors and a distributor already. Any way to modify the distributor to use it with an obd0 computer and do I still have to get obd0 injectors?

 

What D15B, the vtec one?

 

yes

 

Oh.
The PG7 ECU isn't a vtec ECU, and it isn't set up for that engine. And it isn't really able to be chipped. You're really better off getting ab OBD1 P08 ECU, which is the correct ECU for that engine, or using a P28 with the correct O2 sensor. Your D15B comes with a single wire, non-heated O2 sensor, which is good for a P08 but won't fly with a P28. On the other hand, I could supply you with a OBD0 PM6 (Civic/CRX Si) ECU that I've converted to VTEC, but you'd have to get it tuned with TurboEdit or something like that. You'd also have to figure out what's required to make that work with an OBD1 engine; I'm not really sure what's involved there. The only OBD0 stuff I mess with is the ECUs, I don't know much about OBD0 engine differences..

 

What I was looking at was more along the lines of using a VAFC for VTEC and some tuning! Just was using the PG7 ECU because I had heard that it had a higher rev limiter and better fuel maps! I have a friend who has a emulator using turboedit software so how much for the PM6 chipped?

 

$125 for a 88-89 chipped PM6 with vtec and an external EPROM daughterboard. The daughterboard just makes it have an EPROM socket like a 91 so you can change the program.
