Running a 929 with a 954 ECU... help?
TL;DR: Should I continue down this path of trying to make the 954 ECU run the 929 engine, or should I say screw it and find a 929 ECU (which seems to be impossible on it's own).
The long version:
So while searching for parts to use for another build, I stumbled across this sale thread where a guy was parting out a 929 that he was building into a streetfighter and never finished. Long story short I got it mostly complete for $200... one of those things where I had neither the need nor the garage space, but it was too good of a deal to pass up. After shipping from KY to CO and a valve job, I'm still under $1k into it, so doing good on that end.
"Mostly complete" didn't include an ECU. I read somewhere on the internet (so it has to be true... yeah?...) about running them with a 954 ECU gives you better mapping or something... yeah, maybe not so true, but it's sure as hell easier to find the 954 ECU than the 929.
(Side note, why the hell is it so hard to find ECU's for these things? I don't understand).
So I acquired a 954 ECU and harness. Then I forgot about it and acquired ANOTHER 954 ECU a few weeks later... yes, really.
The harness is ran, but a handful of the connections don't quite match up and it's kind of a pain in the ass.
Given that I have no idea if the 954 ECU will actually end up working with the engine, and the fact that I have a 929 harness sitting here, should I just toss the 954 stuff and pick up the right ECU? And if so... where the hell do I find one?
