here is a stock 2003 tahoe with flexfuel.
this is one of my personal vehicles.
yes your vats is on and fans are off.
Wheni write to this stupid tahoe of mine, i have to turn the radio off, close the doors, and uncheck the 'use high speed" for it to work. Otherwise i have to remove the ecm and use my becnh tune set up to write to it.
