Wondering if Turbo edit will work with a pm7 zc ecu? i figured they must be very simular to a pm6 and friend of mine was asking if i could solder a socket on for him and we were gonna run a N/A setup for a LS/vtec

 

Yes.

 

I thought some of the PM7 were like 88-89 PM6?

 

I believe only the JDM PM7 ecu have an external eprom.

 

JD, I think this discussion was on PGMFI about 3 years ago.

We all discussed it... and decided that if you buy us all a 12-pack, we'll let your tyranical idea of the mysterious USDM "non-chippable" PM7 live.

..but really, he may be right, though I have never seen this ECU, only heard of it from him. All of the PM7s I have seen have been JDM, and external EEPROM.

..possible PG7 confusion?

 

Well, I know JDM and NZ (technically JDM) PM7 have EPROM thanks to Mister Ricketts.

It might be an EDM thing.

I've never touched a PM7 ever ever ever... have two F20B ECUs, and been through ten factory chipped ECUs though. I get all the *other* oddities...

 

well I may try it and let you know. this guy also had a pm6 but for some odd reason it doesnt look right cause the spot where i chipped mine is in a diff location and the chip is half the width. I'm gonna make a seperate post about that

 

88-89 pm7's are romless 90-92 pm7's have externalr rom.
i know..I've owned a 89 crx and had a bunch of pm7 ecu's laying around..I still got 2 of thme from '91 with external rom, but one is not sending anything to the relay for the fuel pump and the other ...someone did a mess trying to chip it.
I haven't had the time to fix it yet.
