    Make the MAF fail (i.e. force a MAF DTC immediately (you might have to increase the very low end of the MAF so engine can start and then throws a MAF DTC))... and go from there.

    You have to remember to add CALC.ERROR as a percentage to VE (i.e. add (VE * {CALC.ERROR} / 100) to VE)...

    it is simpler to define CALC.BEN as {CALC.AEM_AFR}/{GM.AFR} and multiply VE by it.

    B3609: you have it set to zeros (correct).

    B3618: this is incorrect (excessively lean, this is why it ran poorly), you are using Lambda instead of EQR... i.e. you set it to Lambda 1.16 instead of...

    The tune contains the tables for the auto trans and the (few) tables for the manual trans... and they are not related to each other.

    In a manual trans tune, just use the manual trans tables.
