Hello
I'm tuning a stroked turbo M20 setup with:
- Wasted spark
- Return fuel system w Nuke rail, Aeromotive FPR, 60lb injectors
- ICV delete
- MAF delete
- TPS
- Spring controlled waste gate
- MSPNP2 + Tunerstudio MS Ultra 3.0.28.
The car starts fine, idles briefly around 900 RPM then runs away to the rev limiter, without touching the throttle. We made incremental changes to the things below, but it did not help.
Throttle Position Sensor - calibrated
Cranking pulse
Afterstart enrichment
Warmup enrichment
Idle advance
VE table
Spark table
Basic fuel required
Rev limiter
Googled the heck out of this. I'm out of ideas. What causes RPM runaway in Megasquirt without touching the throttle?
My Tunerstudio project is here.
