What's even weirder than that is I've NEVER seen a PM7 that HAD an external prom! Weird. I've got two PM7's sitting here right now, no external prom(s). They are both USDM.

"xtensive: ...They are both USDM."

I guess that's the difference then - all PM7's I've worked with are JDM.
To tell you the truth, I never even thought there were USDM PM7's - but then I really have no idea what the US has/hasn't got....

Just out of curiosity are the PM7's you deal with 88-89 era or 90-91? All USDM PM7's that I have seen are 88-89 which would fall in with the 88-89 PM6's in that they don't have external PROM...

Mike, the PM7 only came in the Euro + Jap ZC. We didn't get it here.

PM6 = 88-89 Si
PM8 = 88-91 HF
PS9 = (?)88-91 Ex 4dr
PR4 = 90-91 B18 Teg
PG7 = 88-89 (and 86-87) D16A1 (USDM ZC) teg

Where you buy your ECUs jigga?

They are (I think) Integra ECU's. They sure as ---- say PM7 on 'em too...I'll take a pic.

All the ones I've seen are 88 or 89. Never laid my hands on a 90/91.

so using this on a B16A (even with a ghd compatible ecu) is completely out of the question due to b16a's dohc nature?

No, it's very possible. You just need to modify the fuel table multiplers so that the injectors pulses are correct, and adequate fuel is applied. VTec will obviously need to be activated by an external source until blundar's 1wire VTec code is implemented into a "GhD ROM".

ok correct me if I'm wrong but you can use the 90-91 si ECU chipped with GhD on whatever motor (using vtec activation) and that is using an OBD0 distributor (that i'm not sure of)

Can you put one of these ecu's into a newer car, say a 98 civic EX with SOHC Vtec? I have seen the OBD2-OBD1 harness connectors, but what about getting that to hook up to the ghetto-fabulous ECU?

If it is not possible, just tell me i'm a goob and not worry about it, thanks.
