I have a 2014 L83 with a stage 2 LSXCELERATION cam. Speed engineering headers. Totally rebuilt engine when I installed cam. New injectors, pump, pistons, rings. Valve job, springs. Everything. Just curious on what brand of Wideband sensor to get? And will the location in the Y pipe of the speed engineering headers be ok? Don?t want to get crazy with a huge cam, because it runs really great. Have about 8000 miles on it. But would like my idle a little more lopey/choppy. Thanks in advance!!
easiest would be AEM X series with OBD
which you can log
in terms of choppness this can be done in the tune
best to post and have an idle log

However, Gen 5 vehicles don't have those tables. Instead, idle tables seem to be torque-based. Do we just mess with the adaptive idle torque tables? I see that there are a few rows in there (idle, coastdown, etc), so I'd imagine we just exaggerate the 'idle' row quite a bit? Is there anything else that would need to be done? I saw on Gen 3/4 vehicles that some people had to mess with the idle airflow tables as well. Is there something like this required for Gen 5?
You'll utilize the Immediate Speed Control table on the Gen 5 vehicles.Quote:
