Ich liebe meine Autos!
1981 Mercedes-Benz 300SD | 156K Miles | 2nd Owner | EGR Disabled [Removal Pending] | ALDA Removed | Straight Pipes | GT2256V??? | Laser Interceptor | Engine swap over summer, hopefully with GT2256V attached...
1981 Mercedes-Benz 300SD | Odo Stopped at 160K (at least 50K more) | EGR Disabled | ALDA All The Way Out | Straight pipes | FM-870 Remote Start Alarm System | B100 Biodiesel | AC Fixed x2 | Trunk crushed in
| Retired to garage.Excessive speeding? It ain't excessive till I redline!
Arduino might not be fast enough for pump control, especially on an unloaded engine where rpm will change very quickly with a small change in fuel. It sounds like your setting the PWM based purely on measured inputs, causing the unstable idle because of the response time and over/undershooting the speed repeatedly. Ideally you'd want something like a PID loop which will quickly stabilize at a constant frequency.
