correct.
fuel trims are remembered between map switches
effectively your just switching in separate fuel/timing maps and other adjustments can be made via custom maps. eg di and pi "scaling" , starting injector pulse widths , fuel display offset ect can be adjusted using the map switch mode on one axis
eg for a 91/93/E40/E85 switch
Mode 1/2 no offset
Mode 3 add say 15% to pi/di injectors fuel display offset and cranking pulse
Mode 4 add 30%
when you have flex sensor then you use the flex sensor voltage to adjust instead of the map switch mode. and it would be a continuous adjustment
for the real nitty gritty stuff see ztans opensource flex thread
