Got a few hours today to work with the auto-tune. And a lot of work it was. It's a sensitive piece of technology, that can ruin your day as quickly as it can help you get your maps customized.

The biggest learning for me was that for a really good map with the auto-tune, I had to run gear by gear and eliminate deceleration from the auto-tune processing.

The gear by gear part, eliminates the 'noise' of the lowest gears from the overall map. Not sure the lower gear mapping is getting extra performance, but it definitely helps to keep the higher gear maps 'clean'.

Eliminating the deceleration was really important. That's the part when the Auto-tune goes really crazy on you. In order to do that you basically have to pull in the clutch whenever you would coast, whether on the straight or downhill. Riding like that is no fun for sure, but the Auto-tune does not get thrown off at the 5% setting - which turned out to be important for mapping.

In addition the real time display of the Power Commander display and the Wide Band Commander where essential to getting the map really close to perfect.

I have recorded some 20 intermediate maps, all the way to the final one for the Monster Big AIr + Monster Exhaust (is very similar to the X-Pipe in terms of mapping) + Top Speed + EXUP Eliminator + PCV.

Turns out that mapping the lower throttle positions to 14.4:1 was the way to go. 

Once I was done, I zero-ed out all the 14.4 sections and re-connected the OEM O2 sensor. 

In addition I added a manual +10 in the zero TPS position from 2,000 rpm to redline. Its a common modification to eliminate popping. 

On the final run with the Stock O2 sensor connected, 0-20% zeroed out in the AF target map, 10 at 0% starting at 2,000 rpm+ the bike ran without any surging, close the the target AF at all times and no popping at all. 

For the gear specific mapping to work as designed, proper calibration of the speed signal AND the gear inputs is required. If you are running the TopSpeed Unit, make sure you use the speed signal before the TopSpeed unit, or your gear detection over 130mph will be way off.

I will be uploading maps next.
