My friend installed light weight fly wheel. Now when the ac is on and fan is on high the car will die out when engine is allowed to rev down from above 1500 rpms. So when driving and you push in clutch to come to stop it dies out. The engine slows down to fast to save its self and dies out. It wont do it if you have fan on med or low. Also wont do it the first few min of running. The rpms drop much slower the first 2 minutes of starting the engine even when warm. Raising the idle rpms dont do much unless you set idle to 1500. Anyone point me to the right maps to adjust or tips.
