Sonic 1.4t flex fuel

How many people have done the flex fuel conversion on these cars? What maps are left to tune after you turn on the sensor, or did gm set it up to run well with slight changes for optimum performance?

Also off topic but I'm getting a check engine light off with a p0068 code I belive for MAF/MAP incorrect communication that started recently and throws the car into limp mode. Only thing I notice is before I use to hit 6900 MHz WOT on the MAF hertz and now hit 6000 MHz, and off boost my Barometr pressure reads 12.14 and under boost drops to 11.4 psi. No lift shift won't work and I'm assuming it's due to this. It would go into limp mode once a month at most when it was first tuned over a year ago, to now doing so after 2-3 WOT pulls.

Did you ever get the FF conversion to work?

See this thread for info on the sensor install. There's mention of certain torque management tables that need to be the same for it to work. https://www.hptuners.com/forum/showt...2012-Cruze-Eco

I have a sensor in my Volt, but did not do the tuning.
