when i use to have my evo we had ECUFlash that we used to flash the ecu with different calibrations and tweek the calibration there was also other programs available for the subarus as well i have been having a poke about being new to Audi ownership and have only come across a couple of programs
i have yet to look any deeper into them and i thought i would ask here to see what there is available out there for S4 for altering the fuel , ignition , boost ect and what you would reccomend. Mine is a 1999 model can it also be done via direct port ?
It will be calibrated using det cans and wideband
Any advice apreciated
