Have I screwed up the OCV valve?
Yesterday, my car was running fine, vvt was working well:
when I took the car this morning I found this :
Nothing changed, same config, all was running great and now is running like crap, it wont even idle. I have to unplug the OCV connector to stabilize the idle.
What could it be?

Just a thought, disconnect the battery for 30 min then reload your ecu file, the one you always save before you change any setting (, the data logger shows the output that dives your “OCV”).
It’s a cheap and quick and will remove all power to both ecu’s.
A post on the Adaptronic - forum wouldn’t go astray.

Update:
I found the problem!
I swapped my adaptronic with a friend's unit and everything returned to normal. My adaptronic puts 14,4v constant to the ocv valve, even if I turn off the auxout3 in wari. Also the auxout1 (idle valve) isn't working correctly, it needs 84%DC to start open with my ecu and only 60%DC with my friend's ecu.
I have not tested the other outputs yet, but is likely a problem that affects all high current outputs.
What now?

apparently replacing the blown mosfet solves the issue. a dude on the adaptronic forum found a higher rated one:
Output/Aux 3 is dead, always grounded, need professsional help

Its the diodes or the mosfet. Its possible the mosfet was killed by inductive kickback not stopped by the diodes though. Right now I'm collecting up the adaptronics that are malfunctioning and modifying them. So if you have an issue please email me, and I'll get it changed out.
They have no warranty that comes with the units that I know of, but Adaptronic and Boundary both are committed to making sure the customers get taken care of. If you buy the unit, and something goes wrong, I'm going to get it working for you one way or another so long as I don't have reason to believe it was neglect.
Best,
Travis

In my case the diodes have been those that have failed. Two of them are completely burned.
I'll fix it myself if I can find a source for buying the diodes.
Travis advised me to use 4 diodes in parallel (one on each side of the PCB) instead of 2.
