AF LEan spike after 8.5.1 firmware
Hey, this morning i found out i was running an older firmware, so i updated to 8.5.1
since then i get these terrible AF lean spikes , im half afraid to try again
running map 1, stock 2019 golf R with 7000 km and a drop in filter. 91 octane, A/F wire is tapped to the white wire on the bottom harness , any ideas?
i won't be at the car till tomorrow morning to get the info but I'm 99.9% sure Fuel Bias is all 100 and Duty Bias 0 , boost cut 24 , Fuel OL 40 .
I had 45 fuel OL , on a map 6 targeting 19.5 psi midrange rpm tappering down. a map i tried to be safer with 91. it was fine before the update,, then it gave me lean spikes after the firmware update, I switched to map 1 and put fuel OL back to 40 , drove about 20 minutes and took the log i posted.
i then set map 0 to finish my drive , and was gonna go get some map 0 logs tomorrow morning to see if it does it also...
also as a note i first tried to flash the new Alpha map before 8.5.1 , and it gave me a bad checksum , so i then installed 8.5.
