Okay. So went for a drive. Afr was still pegged lean. Then got a reduced engine power. P0068 map/maf-throttle position correlation

the dtc was set at frame 33000. my efi live wouldnt let me load the pid list you attached. there were a few spots where timing dropped to -15. other than that it was pretty good. need to fix some of the transmission tables. it didnt like the converter much.

I do have some slight leaks on the exhaust slip connections on the y-pipe. Ordered some better clamps that will be here on Saturday

would adjusting C0805/6 cure the P0068? below 30% throttle the expected change seem kinda low?

Also thinking my wideband sensor may be bad. With leaving the key on for 30+ seconds then trying to start it. Could have damaged the ceramic inside the sensor.

New exhaust clamps came in. While their not fully sealed its alot better than before. Most of the leaks are after the ypipe though. The new o2 sensor for bank 2 also came in. Was orginally scheduled for Monday so it was a nice surprise. Ordered a new bosch wideband sensor last night. Will hopefully have it by Tuesday or Wednesday. Should I enable the stft until the new wb sensor is here?

I renabled stft and after about 30 seconds trims went to -25% and the idle started hunting real bad. Guess I'm going to have to wait until the new wb sensor comes in before I can do any more fuel tuning. Got the idle down to 800rpm with a base of 18* would go +/-50 rpms

New bosch wbo2 came in. Got it swapped in. Went to load a new tune with the vve tables lowered in the idle areas but the battery was dead. Seems I forgot to unplug the v2 from the obd2 port along with below freezing temps the last few days. I have it on a charger. Will try again tonight when I get home.

And I have a working wideband now. log showed I need to take an additional 20% out of the idle area on the vve table. got timing alittle better, might need to take an additional 1 or 2* out of the base idle timing. it's also wanting to hunt for the idle but not as bad as before.
