I've read a couple of places that some ECUTEK tunes are running closed loop full-time, but according to the ECUTEK ProECU Tuning Guide (
https://ecutek.atlassian.net/wiki/sp...U+Tuning+Guide), the AFR targets for closed loop can't be changed from 14.7:1.
Is the guide incorrect, and these target AFRs can now be changed for full-time closed loop, or am I missing something (some new/different maps not covered in the guide)?
