I new version of firmware (1.1.80, 1.1.84) iac.integral is frozen if map is higher than in config. But when you shift gears, always you have small decrease in iac.integral as you can see in log:

At idle i have iac.integral -32(1s). When i start driving iac.integral is -34, but when i change gear from first to second (5s in log), iac.integral is decreased to -44. After 4 gear changes iac.integral is -70 and i have problem with car stalling.
IMHO better solution is like older firmware has(less than 1.1.74). If map is higher than in config iac.intergral is 0.
- At this moment I dont have the possibility to open your log, what do you have the iac_close delay set to? This affects the integral-reset so when set too high it doesn't reset the integral controller fast enough. /Larsa
- set is to 255s. With that value and 1.1.74 firmware i had perfect idle at 800rpm. Now i have problems with 950rpm.
