FIS Posted September 12, 2012 Report Share Posted September 12, 2012 I am in the middle of tuning process of V88 on S54B32. Fuel, ignition, idle ctrl, double vanos, boost, everything is working properly except E throttle, I often get E throttle errors 73 Supply Aux 9/10 and 84 Overheat I/C . I have removed return spring on every throttle and dc motor, tried few E throttle and PID setup combinations, I can get stable throttle movement but after few minute run it get 73 and 84 errors again and again.

Simon Posted September 12, 2012 Report Share Posted September 12, 2012 Some times if you are targeting 100% opening and or 0% closed it will bind before reaching 100% or 0% try a target of 98% open and 1% closed to see if this helps. Also make sure all the mechanism is free moving and not binding at all. Quote Link to comment Share on other sites More sharing options...
