I get best results when testing each bank under load not just stationary. I'm no expert on the data logger, but can only say that it's been of limited use to me. The AFR/boost/vacuum/temperature gauge plus my son in the passenger seat with the portable on his lap for two hour on country roads turned out to be my best tuning investment. Have been running the same settings for street and track since 2000, I think. Only fine tuning has been warmup-took patience due to the varying temperatures here in Canada.
Hope you solve your issue.
Cheers,
Johan
