MS2 Extra on a 99 with FM turbo kit, 550cc, MTX-l wb. Car has been running good for a couple days with good/normal AFRs. Car starts well hot or cold idle is set at 950-1000 oscillates a bit but not really bad. The last couple days its running unusually rich AFRs from idle and also when driving. Iv tried changing the VE idle cells which seem to change the mixtures a bit but after a while it goes back to 10:1 sometimes down to 9s. Tried changing the settings on the MAT correction table, warm up enrichment, tried disabling EGO control. nothing seem to make any difference. first start usually @12-13 but after a minute or two its back to 10s. Iv reloaded the map reverent supplied without changing anything but its still the same. Even with the very rich afr the car still starts well hot or cold, idles ok just eye watering rich and very bad mileage. Heres the msq and a log (logged with no boost and low rpm)

Do you happen to have any datalogs from when the car was running well?

heres one ..as you can see the afrs are ok
Attachment 72953

this has different timing map and some minor differences to your original loaded map..but even loading this one now wont make any difference with the afrs. its like the ms doesnt respond to any fuel setting changes even though the settings are burned into it

Interesting. Your pulsewidths are still the same.

What injectors are you running?

looking at the two logs which basically has the same settings theres a big diffrence in the afrs..the second log is car just idling also the last bit of the first log car is also just idling but its 13-14:1 compared to 10:1.
also on the first log the afrs are all over the place for such a small range in the map no boost/low rpm
