BMW Ethanol sensor & ECU Meth control?

mynameisplayer · 01-15-2018, 12:49 PM

Is anyone doing homework on the F80 ECU doing Meth control? Is there a table in the GTS flash that has output on a pin for the water pump?
Also has anyone looked at the Brazilian Flex fuel ethanol sensor?

Looks a lot like a generic GM one...

The tables shown are for an N55, being adapted to S55 for E85 flex fuel using those types of sensors, but could be adapted to water or methanol injection or other control schemes.

Discussion here about GTS water injection system including the pins but no info on the tables: http://f80.bimmerpost.com/forums/sho....php?t=1456674

so is it possible to add flexfuel to the S55 ECU?

Yes, I am working on it. The Brazil flex fuel setups I have found info on so far do not have the performance related table blending tuners will want, so custom code is needed. Not done much more on flex fuel in last few days as was finding flash counter code (now found and testing).
