I’ve copied Greg on this email. I’m not sure what is meant by not enough resolution and which maps it pertains to
The maps in the latest flex fuel firmware in Nistune now have full 16 load x16 RPM cells for fuel and timing flex control which is better than some aftermarket systems with regards to content adjustment over the entire map
The flex input has a 0-100% ethanol content range which can be scaled against the maps in 3% increments (using scale 0-31) using the fuel and timing content scalers, which should be sufficient. I can always increase this range in the firmware using lower increments if required but did not think it necessary.
If there is any issue with resolution I can always increase it if necessary but so far we have found it to be sufficient during testing
