Tuning advice/questions

[captndave737]

So here are a couple of pulls I made yesterday. The first one I get 3 deg. KR at the same time as a slight spike in RPM. Actual A/F is slightly richer than target A/F. The second no KR. I'm new to tuning with FAST so I'm looking for help in figuring out what's happening. FP rises 1-1 with boost.

Probably wheel spin. Thus the spike in rpms.

That's what I was thinking since the wheels did break. Would that be Knock or false knock then?

False = wheel spin

The way to check for knock is to find a long safe road and slowly lay into it in 3rd without a downshift happening. If you get knock then I would say it is real.

Or use a dyno.

Thanks Steve. Didn’t get any knock on the Dyno with Clint.

Just because it pulled clean then doesn't mean it will the next time. You have to watch it every single time you hit it.
