Hi

Is there an explanation for advance adjustment when using twin 20x14 map, it is a finer adjustment than using single map.
When looking in the manual page 150, I wonder about the values entered in the chart ,

Can't answer the query as you appear to have answered it yourself? But whatever - those two maps have some whacky numbers / curves that IMO shouldn't ever be loaded into an ECU or even taken as a recomendation for a baseline?

So you're just asking about 2d vs 3d compensations ?

ie TPS vs RPM for main load, and then these tables for further adjustment ? ( or visa versa with MAP as main load and a TPS table adjustment )


Yes it is clearly to give a wider range of adjustments for any anomalies or difficult areas of tuning. IMO, unless it is an unusual or difficult setup....just stick with MAP vs RPM. It's easy, there's no messing about with multiple tables.

It's to allow fine tuning of compensations.
Values shown are made up, as this is so rarely used, we don't have anything useful, and also will be so different engine to engine, there's no correct values here.
