Car: 08 335xi 6-MT Coupe

Mods: Cobb Stg 1 Agg and DCI's.

Issue: Car is sputtering in higher gears 4-6th, I'm thinking the coil packs need to be changed but I wanted to see if I could do some Data Logging with the AP and see if i can tell exactly which coil (if it's just one) is giving me the issue.

Question: What parameters should I set the Cobb for Data Logging, Ignition? and Boost? Just curious what other people's data logging experiences were and what methods they used for diagnosis.

Thanks Buds!

How old are your plugs?
