Re: fuel cut logic for boost control

yeah I will pick up more of the fuel logging parameters. Initially the fuel cuts just coincidently happened near the map target. I since ran lower map targets and everything ran happily. The HPFP is nowhere near target when this happens so I'm going to log its parameters and also change the split to...

think I eliminated MAP limit related fuel cutting, still have fuel cuts on me and seems to be more correlated to total fuel flow / fuel supply pressure might not be up to it.

fuel cut logic for boost control

Seeking clarification on this. Running 1.87 n54 pnp kit. I've been having fuel cut kick in to manage manifold pressure where the manifold pressure exceeds manifold target (Wastegate Control -> Manifold Pressure Target) and as modified (reduced) by target adjustment for gear (Calibrations -> Boost Co...

Additionally looking at lambda just prior to the event, appears it went lean abnormally while fuel was still being delivered and then increased while in closed loop. So the sync issue might have come about from that as it was thrown as the engine died?

Sync Long Tooth Gap, appeared and disappeared?

New Syvecs user here with a N54 PNP kit. Had a Sync issue this morning which left me stranded for a while and wondering what I should be looking at to determine the source of error. Car has been running for 5 days or so, initially on a base file sent from Syvecs and I’ve been in the process of makin...
