Crankcrankcrankcrank... '99 n/a MS3 - No Start
Trying to get my car fired up on a Brain-built MS3. No RPM signal, it just cranks and cranks and nothing happens. I've screwed with a few things (injector size in the pre-loaded tune was set to 420cc or something like that), but still not getting anywhere. What glaringly obvious thing am I missing? The car is a '99, 84mm/8.6:1, stock fuel and spark. Crank sensor is where it needs to be, and this ECU has been back to Brain for some tweaks to correct stuff the PO messed with. I *think* the board and harness are good. I did add a knock module, following DIYAutotune's instructions.
MSQ and startup log are attached.
Use lube please.

You ain't got no synch!
Next step is to take a composite log and post it here.
Set Spark Mode to "Log crank&cam", make sure to power-cycle the MS, then record a composite log under the "diagnostics and high speed loggers" tab.

Try this (not 100% sure if this is correct, but give it a go): Turn R56 about 12 turns to the fully anticlockwise position (you may or may not feel a “click”) and then turn R56 back about 6 turns clockwise.
Then take another composite log and see if it shows your crank signal.

There is no endstop on the pot. So you did that right.
Still no crank signal. I suggest you check the wiring. Again, I'm not 100% that my setup instructions for R56 are correct for a brain-built unit. But if they are you probably have a problem with wiring.

Yep... getting to it. Opened up the MS and looking through everything to see if anything stands out to me. It all appears as it should to my novice eyes, and I have continuity across the harness for both crank and cam. I'll crimp on some connectors to the cam and crank wires in a moment here so I can flip em.
