Hello, all!)

I flashed my Airtrek with Evo GT-A firmware (80700010) because of 3-port BCS functioning incorrect with stock firmware (89970010).
Open loop is always on.
My fuel maps have 14.7 around idle loads and rpm, but I've constantly getting afr map 13.83 in logs at idle. When I were using stock firmware 89970010 there were not any issues like this. I've tried changing many maps that can somehow influence to this, but no success. I've attached a piece of log and a corresponding fuel map.
Will be very appreciated for any help! Don't want to waste my fuel ))

Either change the maf table at low frequency or lower injector latency.

What does your 3,4,5 fuel map look like and/or your lo octane maps? I've seen xmls with the maps labelled incorrectly. Are all at 14.7 in the idle region?

That won't affect AFRMAP. It will affect the actual AFR.

Yep, all maps had 14.7 around idle region. And fuel maps are labelled correctly.
Solved the problem by setting open loop periphery bit back to 1 and switching it off another way - by setting "min temp for closed loop" to 150.
In 80700010 that periphery bit works incorrectly.

Cool. I've never actually used the periphery bits for open loop. Always either use the coolant temp like you have or use the load and tps tables.
