I get the S4 towed to his shop and we check all of the fuses and relays to find all were good. Next day after talking with Achtuning I get to borrow a ECU to see if the car would start. Sure enough plug it in and the car fire right up. So I buy this ECU from them and the car is good to go.
With the ECU I got from Achtuning it came with MTM software vs. APR software. I'm actually liking the MTM software better since I'm boosting around 18-20psi vs. the APR software boosting around 15-16 psi.
