Not to mention, I'm sure Jamie will help to resolve the problem.
It's odd tho, I've never once had pinging issues with my set up. Even when hotter than hades. Maybe you're in too tall a gear for the load? I rarely shift before 3k and when I'm in 6th RPM is almost always above 3k...
You might consider "Load copy current tune" (wording is weird, but it downloads a copy of what's in the ECM) to the Power Vision unit, then take the PV unit to your computer where WinPV is installed, hook it up and download the "Copy of current tune" and the tune you got from Fuel Moto. Open one tune, then load compare. If you don't see very obvious differences in the before auto tune map and your ECMs current map, then you may not be doing Autotune correctly. It's easy to make a mistake in the process.
