Tune 20222?

I'm trying to learn tune ecu. My rocket is an 05 with a Dave platt cat delete k and n air filter under the seat, stock header and mufflers . i haven't done any changes yet, but from what I see with it all plugged in. I'm running tune 20222 and running a a fault code of 0505 (faculty idle controller) I haven't downloaded a new tune yet. Looking for suggestions on a more current tune and a resolution to the fault code.

In any case a canned tune off the internet cannot be trusted, always a good idea to get it verified on a dyno.

You can also use TuneECU to cycle the idle speed stepper motor too - might help problem solve the fault code

20228 is the current golden child. Look for variants for your intake/exhaust setup.
