Experienced Haltech but New to UpRev

^thats weird. What exactly do 85-105 mean? Like is 100, a fueling situation where the ECU doesn't have to add/subtract fuel? Then 85% would be akin to taking away 15% fuel?

If the ECU is going into open loop fueling, then your right. You won't be able to see any correction being applied by the ECU. You'd have to compare the AFR called for, to AFR seen on the logs. Can you tell if the fueling correction stops at a specific g/s value (which might indicated a different airflow correction range being encountered) or a general throttle position/RPM area? (which might mean that you've reached the CL/OL threshold)

Man I can't wait to get my Z. Thanks for posting up self-tuning info meaty. It'd be nice to make this thread a resource for other self-tuners.
