I've got a Vance & Hines 2 into 1 Big Radius and I've done nothing to the pipes.

 

Or.. you have an exhaust leak

Or.. you need to change the AFR just a tad in the decel area


if your exhaust is not without a baffle, and you check for and have no exhaust leaks, then send your autotuned map to Fuelmoto. Tell them you have decel popping. They should be able to fix you right up...

 

Check this thread out, running the update as suggested helped my tuning process. There may be tables that are not showing up for you.

Just a quick update.....


I've read a lot of threads regarding the Auto Tune for the Power Vision and a lot of fellas are saying to run it 3 or 4 times and that's all you need.

I had to run the Auto Tune function 8 times before the bike would run better. It ran like crap after the first 4 attempts and began to get better after the 7th attempt. I am satisfied now after the 8th attempt and will keep it as is for the time being. It finally got rid of most of the "decel-pop" I had in my exhaust. I can still get it to pop but it's way better than it was initially.

Just thought I'd let the rest of you fellas know that it may take a few kicks at the cat to get the tuning down.

 

getting ready to install my powervision, do you leave the monitor on during auto tune sessions?...was thinking of mounting mine somewhere on the bars for the extra guages due to that i have very limited info on my bo guage

 

Yes, you require the PV connected when doing your AT sessions. After you are satisfied with your tune, you can remove it once you flash the final tune.

The extra gauges are a nice add on.

 

thanks man!
