hp tuners self tuning out there

[ViperGTS14]

Your oem tune is saved, it is easy to go back.

The problem with doing WOT logs is the fact you do not have a WB to watch the A/F, these cars run almost a point diff from dyno to track. Another issue is, you really want to log Knock Retard (KR). I am not quite sure you can be nice.access the enhanced PID's with a G5, the KR is an enhanced PID. When i was using HPT I could not access KR as you can on a G4, however, a newer release of HPT may now have this capability.

If you can access KR, find a load type dyno such as a Mustang, you can easily dial in the max timing, therefore, max power. A WB would also be nice.

I'm following you Jack. From what Torrie stated the amount of tunes he has done to these Vipers he has it pretty well nailed down. Time will tell, I don't have access to a mustang dyno only a dynojet.

Let us know if you can access KR with the latest version, maybe, you can ask Torrie.
