Starting to run lean at cruise
97 Miata 1.8 with MKturbo, ms3pnppro, 640cc ff injectors.
I had the VE table and afr table tuned really well and was.going good, but recently the afrs have been creeping up and I don't know why. I haven't changed anything. It still runs perfect afrs under boost but when I come down from a pull or just coming down to cruise after accelerating the afr will creep up to 16.2ish while cruising like 3k rpm 45-70kpa. I have tried raising the VE table numbers in that range and it doesn't help. Other conditions its perfect.
Any ideas? I can post a log tomorrow when I can get my laptop.
