Please correct me if I'm wrong...
The idea of having two timing tables is to compensate for different octane fuels.
My understanding is the ecu will clip the max timing to the corrected MBT table.
If I was to fill the borderline spark table with 50s, could I then use the MBT like a standalone/traditional timing map and only run on high octane fuel?
If so, what are the drawbacks?
Thanks
