Little update; I must be one of the first to fully integrate the flex sensor into the car as the original patch from Ecutek had the ethanol content reading about half the actual E% value. Needless to say I noticed this right away and contacted my tuner. My tuner then received a new updated patch from Ecutek within a day. I will say I'm very impressed with Ecutek's quick response and resolution. My ethanol sensor is now reading perfect around 37% at the moment.
I also have some new plugs on order and hopefully will be here soon: NGK SILZKBR8F8S (BMW PN#12120042724 - N20 Flex Fuel Spark Plug) I plan to gap them around .020. If anyone needs these plugs hit up Brian Keller at Sun Motor Cars for the best price -
