FED UP. electrical wiring woes inside M30 related

[Mr. Burns]

I have. Fuel pump, flow, cat, spark,maf,iac,etc etc.

Im looking into megasquirt at this rate...considering I may boost in future

My m30 swap has been hit and miss when it comes to drivability...my birthday passed, and my car failed the smog test MISERABLY.

Long story short, I used my factory M20 harness when I swapped in my M30.

I ran into TPS sensor issues (reading WOT) when supposed to be at idle, reversed that reading, and worked well for awhile...ran pig rich.

Eventually just coughed and died even when trying to turn over. Plugs are charcoal....

I've purchased a legit M30 5spd harness, and will be removing the M20 harness.

I'll be doing this in hopes of resurrecting my project to run properly in order to pass the smog test legitimately.

the TPS issue should be resolved, plus the wire fitment I would assume would be a little cleaner/tighter.

has anyone else given up on their M20 wire harness with M30 engine and swapped over?

I feel so aloooooone:(

The M20 harness is easy mode. No modifying except for wire lengths, and there's barely any of that.

How are you sure you don't just have regular old E30 problems unrelated to the engine swap? The M20 forum is full of people who can't troubleshoot their stock setup. I would go back to the diagnostic basics before radically changing your hardware.

Well, I went and bought a basket case 944 instead of tackling the wiring on mine, so that tells you how I felt about it. But all hilarity aside, the m20 harness shouldn't be a problem unless there's something wrong with it physically. I'm only repeating what I've read on that though.
