Wierd problem !
I am trying to solve a car that have a modifyed sw,engine , big throttle and cam and i can not make it work as supposed when i go from idle to off idle ( part load ) ,the engine goes deadlean and it annoys me and my customer alot , the engine runs okay at steady state , but suffer alot when i try to "just drive away from a stop "
I have been able to cure some of the problem ( idle speed to high when the car is rolling , lean spots and other "funny " things but the Lean , transitation mode when the throttle gets moving from idleposition ( 17% ) to 20-30% ( part load ) is still there .
I am seeking for a total stock sw for this PCM , so i can test if this is sw related or something else ( could be the big throttle that cause this , so i will also test a stock throttle and see if that cures the problem .
Attached is the sw that the car did have when my customer did leve the car here for fixing this problem .
