Thread: Octane & Compression tuning

I just purchased an ECU with a tune for boost, 8.5:1 compression and 91 Octane gas, and will be copying the .bin over to my Calum Realtime. My engine is an NA AWD DE, so it's most likely got 9.5:1 compression (maybe 10:1, I don't know), and 93 octane fuel readily available in my area. What changes should I make to get the most out of the tune?

Thanks,
Chris

Honestly, the 8.5:1 tune just adds more timing and runs a smidge leaner from JWT and the fact that JWT did everything very rich to begin with, you probably don't have to change much at all. Most of the Calum BINs were formulated from JWT bin files and comparisons back and forth. You can do some timing/ignition map comparisons with other BINs but I doubt they will be very different.
