OFT vs Delicious [E85 vs FlexFuel]

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

Boy that's the truth. Thanks Zach.

Used both OFT and Delicious tuning with flexfuel...not ever having to worry about e85% is very nice. Oh, and map switching on the fly is nice with Delicious/Ecutek.

Thanks everyone for all the great input! For now I'm fairly happy with the idea of saving up my money for a bit longer and throwing down for the Delicious kit. A couple years ago, I would have gone the cheaper route, but these days I have a little bit better income and a LOT less time to worry about whether I messed something up. #Lazy #GoFastParts

Side note, we actually have tuned quite a few ESC kits.

@Zach, Good to know! That was my biggest concern. I definitely like the setup and hardware you guys have. When I can afford it (especially after the cost of my next couple of parts ) I will be looking to you for sweet sweet Delicious-ness.

Just curious, do the injectors need upgrade for ESC+ flex fuel?

On this particular setup, the boost is so low that we can get by with stock injectors. More savings!
