I have 2 words.

Ecutek bug.

I am still working through it but that's what it was all this time.

Could a mod add Solved to the thread title for any unfortunate soul who has to search about the same problem.

Care to elaborate?

Flashed it back to stock and the minimum angle of 0* was attainable on both banks not just bank 1. I then reflashed the last tune I got and everything is still reading properly.

Step 1
Using 2 wires with female spade terminals I electrically actuated both banks to 0* VVEL. Bank 1 requires deadpool hands.

Step 2
Disconnect battery for 10 mins

Step 3
Reconnect battery but leave VVEL motors unplugged. Set VVEL position sensors as per manual 0.5V.

Step 4
Turn ignition off and reconnect VVEL motors

Step 5
Clear CEL's and I was good to go

Now after doing all of this. Car starts up and all readings are good, hits operating temp and goes into diesel mode, bank 1 goes super lean and bank 2 goes super rich. Next step is to replace the wiring harness.

Really well done on working out that evil bug!

A new evil bug has appeared so I'm replacing the heads and VVEL ladders. I'm starting with fresh mechanical items from a known working car.

Currently with the VVEL all good as far as the sensors say. The car will start up with Bank 1 pegged lean and Bank 2 in the 12s AFR wise. If i give it a little throttle and let off slowly it will clear up, fuel trims and AFR's will be normal until something (no clue what) causes it to go back to ****.
