Default why cant you chip a PM8?

why cant you use a PM8 from a HF to run turboedit? its a MPFI ECU... are there some hardware conficts or somehting? it should be about the same as a PM6 right? P05 and P06s are about the same...

so whats up?

because they dont have an external eprom to desolder and replace

sure you can desolder the MCU and put in a socket and an adapter board or wire up a separate board off the MCU without desoldering it to add the external prom, but thats a lot of work really

ZDYNE replaces the whole MCU, thats why they could do it in just about any OBD0 ECU.

We dont just know what MCU brand they replaced the stock with.

Lol..
I have a PM8 right next to me..I opened it up and there is a external EPROM..
And what is weird is that it says PM7 on the inside of the plugs...maybe someone put a PM7 board in the PM8 case??
But the guy I got it from was running a D15 8v engine with it...

Weird, and not only that, I think the JDM/EDM PM7's are the only ones with an external Eprom. The USDM's do not from what I know.

So he stuck a JDM/EDM PM7 in a PM8 case...
