I got problems with my ZC, finally got it turbo'd on christmas eve, everything seemed to be ok, I started it up yesterday and took it for a spin and when its not boosting it feels like its misfiring, it seemed ok when on boost, but now even when its just idling it runs shitty. It is a euro spec car so it has always been a ZC I got a PP5 ECU and am running the PM6 boost bin that comes with Ghettodyne V2.3 it might be just cos the car hasnt run for like a month, anyone got any suggestions before i fix it with a gallon of petrol and a lighter. . .

I live in Europe...PP5 ECU?? what year CRX do you have?
In my '89 CRX there is a PM7 ecu.

I got an 89 it had a PM7 in it but i changed it to a pp5 because that as the only re-mappable ECU that i could find and it's out of a honda concerto, oh and i just took it for a run and its coming up with a oxygen content CEL and i dont have an o2 sensor the car that i took it out of did though an i'm starting to get confused

Semnos

put a O2 sensor then...look up in the wiring schematic for the concerto where to hook up the O2 wire on the ecu connectors. with a CEL you're running on limp home mode...I would either make an adaptor board for the PM7 or get a newer Pm6 to chip. I don't know if the PP5 uses the same code...if it does just get a O2 sensor

Any idea where to hook up the o2 sensor i had a quick look at the schematics but haven't really had time to study them, i noticed that my old PM7 had a sensor of some sort mounted on top of it and the pp5 doesn't what's all that about. Anyway i just got the stock PM7 fuel and ignition tables and edited them on turboedit with 1 deg/psi retard and a ---- load of extra fuel and it runs a lot better still has a couple of nasty halts in it though.

the the thing on the Pm7 is for the IMA sensor whatever...you can adjust the idle with it to....it's something ..Intake manifold bla bla don't remember.

The cylinders are even across the board, injectors are ok, new plugs (got rid of the bosch 4's) leads are ok . Damn, losing interest fast anyone recommend a good boost ROM and should i keep that little sensor on the new ECU even though it dint have one

Semnos

You don't really need it...it isn't connected to the ECU either it's just uses the ecu as a bracket.
Check the new boost rom on PGMFI try17.bin

right so i got the try 17.bin onto a chip and it started ok no cel went to take it down the road and as soon as the car moves its like its getting the spark cut out i checked that i hadnt put a speed limit on or owt stupid like that all seems good but it dont run. Everything seems to be coded for PM6 ECU's could this be the problem?
