you have to add 12v pin 37 with v2.2 board make sure you have F2 soldered or otherwise jump the pads

Thanks. What are F1 and F2 for? Do I need to jumper them both?

F1 and 2 are fuses to protect the board if something got shorted. F1 for the optional tinywb controller and f2 for main ecu.

[walinsky]

Ah thanks.
Sorry for the confusion.
F1 and F2 are on the bom on oshwlab.com but not on the google spreadsheet
I used the latter one...

Raku, not sure if I am the problem but what VR chip does your board use, I cannot see it? Assembled 1.7 board and testing successfully to date need to branch out now to other inputs.

[Raku]

there's no vr conditioner on board. you can use max9926 based dual conditioner

[Raku]

alternatively you can yse m52 hall crank sensor directly

[Chipboy]

Apologies, none on board but your recommendations are what I was missing, thank you. I will source / build the max9926.

[Chipboy]

Looking at the schematic and checking the board the second set of inputs are not used (MAX9926) so it should be possible to use these for VR CAM signal? With custom wiring of which there will be a lot.

4 IGN circuits
VR Cam
4 INJ (need 2 more)
MAP
4 wire stepper
plus others I am sure

Thankfully the loom already si just need to work backwards from it .This all fits into the existing 55 PIN socket the same as the Motronic 1.3 so its an extension from it,.

[Raku]

Yes on v2 boards support sequential fuel up to 6 cylinders

[Chipboy]

Only have the need for four! Thanks for responding and here is the engine.
