Need some help here
 

Hi i'm Henry from Indonesia, i have some big problem here. I work at my customer car. Rx8 with 20b engine single turbo gtx42. Microtech lt16c+x6 box. This purpose for daily use car. Engine is stock, never rebuilt. My problem is the engine idle is so rough, i have tryin to sett the auxair in the screen 29. But i haven't met the stable idle. I red the Lt manual book but have a different features. There is AuxAIRafs for control the opening bypass valve, but in the ecu don't have this feature. I'm trying to pump some gas in the street but the engine was cut in 7k rpm i didn't know why, because in the status box was blank. I have work this engine in 2 years but haven't met the best setting.
Please anyone have the sample setup for 20b engine?
