Message I don't think modern flex fuel cars really care what the ethanol content is per se. They use O2 sensors to tune fuel mixture. They use knock sensors to adjust timing and boost. Is there anything your Z32 tuner uses that can't be (or isn't) installed in your modern flex fuel car? Ok the roller. But the car has the road and sensors to measure performance.


Thus, in my opinion, the modern flex fuel vehicle can do what your Z32 tuner does and do it 100 times a second. Sure it can't fix a boost leak (or swipe your credit card).
