What i did before i bought an ECU was download the tuning software and just play around with it, and see whose software is most user friendly. Tuner studio is a great software, and very easy to use.
Thxs for rubbing it in guys lol. Maybe i'll just say screw it and buy a a9l sucks i just had one tho. I don't think self tuning is for me my wife already hates my car and more time with it might put me by myself.
I wish there was a way to make them understand its an addiction. A week ago she actually asked me if I had to chose between her or my car which would it be.
I being married to a Wife who has owned A '68 Charger that she built with her Dad, a Firebird and a Camaro, she understands. So I am lucky when it comes to mod's or performance on my Mustang because I married a car gal.
