I am looking into the Vi-pec V44 for my 97 WRX. One of the most praised features I can see in it, is it's Auto-tune ability.
But in the manual, it states to run the auto-tune in a controlled scenario (eg Dyno) So the "Quick and simple user-friendly" Tuning method, still requires a $500 trip to the tuner, which is no easier then any other ECU.
Am I correct in saying this? Or can this auto tune feature be used with all 4 wheels jacked up, or on a long abandoned road?
Do all ECU's need a Dyno for a tune? I will be doing my WRX up progressively and think spending $500 for possible 3-4 tunes a bit much.
