Dave, what does the driver's side look like (temps)?

 

That side is not visible from the top. I'll get it up on ramps tomorrow or Sat and shoot it from the underside and report.

 

I will be excited to see what you pick up with this turbo... also hope you get it running properly!

16 or more crimp splices - not sure I'd use that method of connecting all those important wires.

 

Lol... no, I'd never do crimps on something like this. I always solder anything that is even remotely permanent.

Good news today! First, when I arrived last night, my new EFI fuel injector tester was already here. So, first thing this morning, I went out, lifted the hood, started the engine and then took the tool to each injector. Only cyl#2 was intermittent. I'd broken that connectors wire awhile back by leaning my forearm on it routinely as I worked on this that and the other over the years. I redid the wiring at the time but it must have been a crappy effort. I pulled off connector #2 and probed it with my multimeter. It's getting a full 12v but who knows if the PCM/Acceleronics box is pulling the circuit to ground like it should. So, as a test to see if it was the injector itself, while the engine was still running, I kept conn#2 off injector #2, then pulled conn#4 off of injector #4 and put conn#4 on injector #2. When I lifted conn#4 off of injector #4, the idle dropped noticeably. When I clicked conn#4 on injector #2, the idle picked back up. I tried that a few more times to make sure and each time the idle behavior reacted the same. That convinced me that injector #2 was fine. It must be either the connector or the wires.

I have a spare 96 M6 Wiring harness that I bought a few years ago so I could cannabalize the connectors when I needed. I cut conn#2 off that spare harness and replaced my stock conn#2 with the spare. After it was soldered and heat shrunk, I started the engine again. Viola! It runs smooth! I took her for a test drive and it's excellent

I'm still dialling in my SD tune but I can tell you, the intermediate throttle response (idle to substantial boost) is already immensely better. Much more crisp and authoritive. I suppose because the fueling is applied in a more linear fashion as opposed to my prior MAF tune that just dumped fuel as soon as the MAF max'd out.

My new turbo got here a week or two ago and my new Hotside should be here next week so I'm pumped!
