Hi all, Ive got a na half bridge running the s4 pnp. I know the ecu came preloaded with a stock t2 tune uploaded, I cannot get the car to idle at all. It starts up super easy, then the bac starts pulsing hard to keep up with the bridge. Its duty cycle is jumping around from 20 to 58%. Im newish to tuning and new to adaptronic. Can anyone give me some pointers or maybe help with a base map thats for an na bridgeport?

 

You should unplug the BAC, and get the car to idle hot, at a desired speed before using any idle control strategies. This will all be done via ignition timing, idle afr, and throttle body settings.
