Power Commander or Race Tuner?

PCV with auto tune will tune itself.

TTS mastertune

YOu need to find somebody that knows the unit and knows how to tune with it.
And everychange you make to yer motorcycle, you need to go have it redynoed again.

The Thundermax with Auto tune, You replace yer stock HD ecm and use the Thundermax ECM and wide band oxygen sensors.

I'm not clear on something. The PC V auto tunes. Is that a fine tuning after a dyno, or does that mean you skip the dyno tune?

The map you git with the PC is a close map, you don't have to tune.
But I like to make sure the timing and everything is closer and let it tune from there.
I rode for many months without tuning the PCV.

The Thundermax unit I like much better cause its not a piggy back unit.

One of the most important thing in a Map is the cam.

If the right cam is not chosen in the map the timin might be off. This is a big factor.

So when you take a bike with Auto Tune to a dyno person, you need to tell them which cam you have and the mods.

If you have the cam specs that will even be a Plus.

Then the auto tune can better do what its suppose to do.
What auto tune can't do is change timing , it changes Afr's by reading the o2 sensors

Thanks Cardboard, very helpful.
