I just had my car SD tuned and now it idles bad. While sitting at a traffic light, my idle is not good. AF is low 11 - 11.5 and it was maybe high 14's or low 15's. I was just curious if anyone knew what could be the problem. I haven't used my EFILive much at all. If it was something simple that a dummy like me could change i would appreciate any help and suggestions. Thanks guys.

Might try tuning the VE table some in that area. Use the Bidirectional controls in the scanner in the control panel to find the ideal fuel and spark for your setup. I use the delta spark which adds or subtracts from the commanded timing figure.

Part of it could be your injector settings Scott. If I remember right you have 60lb motrons and the idle is a little harder to get dialed in. I would double check the ve table as well as the IFR table, default and minimum pulse width for those.

Nice numbers you guys got out of that.
