Who do I throw my money at to test a dead MS3X?
#87
It's possible, I took composite logs in my last post and they didn't seem to indicate any sync errors while revving (just when cranking). I guess the best method of testing is to bypass the ground for the main relay outside of the MS3X and see if it still clicks on and off.
I've done that. I uploaded a zip file with everything in it right here ⤵

Yes. On top of that the car didn't start at all today. I had to swap over to the stock ECU to get to work. Here's what it was doing when cranking (before it quit starting):
Closer view:
Like I said, adjusting my trim pots doesn't seem to help any, so I defaulted back to 12 turns counterclockwise and 7.5 turns clockwise. I'll take more logs later today with the no-start issue.

that cam signal looks odd.
this is an NB? can should be a single, then double.
you're getting loss sync where the cam turns into a bunch of a 3 edges.
did you tune the two pots on the exapnder board itself? that's cam. back them both out CCW at least 6 turns. only rotate r11 back CW 3.5.
when you cure the sync loss, youll cure both the startup issue and the 4k drop out.

"Fantastically" was how it reacted. Thank you. Starts up reliably and quickly now. Still having the 4k cutout though. Something I noticed was the tach just completely dies when it happens and then comes back once I'm lower than 4k. I'm hitting around 9-8 afr when it happens, but wouldn't autotune try to pull fuel if that were the issue? The tach dying tells me something isn't syncing and my RPM signal is dropping.

Now I'm on the hunt for what's dropping at 4k. It's hard to tell but I'm guessing my sync log should show me something? Should I be taking a composite log at 4k?

I updated the firmware to 1.5.1 just to see if it'd make a difference, but it didn't. Here's what it's doing:
If you notice during the sync loss there's a(/ a few?) relay/s clicking when it happens under the dash. Watch the TPS, when my foot is off the gas It takes a while to idle back down afterwards too.

you hear the fuel pump relay clicking, cause it turns off when there's no RPMs.
do a composite log and capture the 4K dropout, see what sensor is actually cutting out (cam or crank) adjust r52 or r11 accordingly.
