customer just dropped me this log file and tune, the engine is going into fuel cut and stalling during idle situation for no apparent reason!!
overrun fuel cut is set above 2000rpm and you can see this working most of the time but if you go to 15:30 point on the logging you can see the rpm is down around 1200 throttle is open and fuel cut is still active!!
I cant seem to find the cause! any insight appreciated,

Re: weird fuel cut situation
Good morning,
i think the problem is the oil pressure cut and it is active at this moment, because your Oil pressure restart time is set to 5s and in your logfile is see at two situations that the fuel cut goes off after 5s. And the oil pressure is often nearly your values in your oil pressure cut table.
I can´t find something else in your configuration.
In your situation i would test it without the oil pressure protection.

Thank you Jan32 for taking the time to have a look!,
It didnt actually look like it was going below the cutoff but i did consider that so i lowered the cut value and restart times and sent it back to them, i didnt hear back so probably it fixed the problem. It has been fine until now so i wondered if there was something else i was missing.
