Guys any suggestions to what closed loop bias I should use to complete my data runs for my 2010 1200 Custom? And what should I set them to when I have finalised the vtune??

Good question when you find out I would be interested to know.

The latest update recommends 664, but It dosn't change in those increments, it was ever 660 or 680.

What I ended up doing was leaving it where it was and doing my V tunes like that.

What I found was while doing my tunes the old girl ran fairly hot compared to normal, but once I had finished and put the AFR back to original, it ran a lot cooler.

I also found you have to give it a good floggin to get the high TPS readings on the charts, as I said in my post, I rode it like I stole it in my last 2 V tunes.

And you will be plesantly surprised with the difference it makes.

Just the canned map you start on will make your old girl boogie and it just gets better every V tune.

Hope this helps

best thing about this system, is if your not happy you can fiddle with it until you get it where you like it.

Am waiting for a day with out rain to do some data runs. Hoping to feel some difference as the canned map didn't make alot of difference at this stage.

I have S&S slip on's and a Hypercharger Pro R and mate what a difference it makes, I was upto 165 in third and and ran out of road and it was still pulling hard.

goodluck with your runs.

Don't know what rain is over this side

Hi Guys

Finally got some data runs done and created a new calibration. A couple of questions?

Still pops a bit between gears and decel. Is it ok to reduce the decel enleanment figure to richen the mixture a tad? I thought 5% for starters??

When you finalise your calibration I didn't read that you have to put the CLB back to original? Does anyone have experience with this??

The final VE tables look to be all over the place, is this normal or have i stuffed up??

Cheers Guys

Mate I noticed the same when I was doing my Vtunes, but when I set the CLB back to original it stopped.

Guys, here is a sample of 2 data runs, do you think I have enough data for the Vtune process??




 

Cheers Bakes, i did select the Sportster VE for the data run, just not when I restored the histogram to post here. There is a major difference in operating temp between the models due to the location of the temp sensor.
Will try another run and see what that looks like. Once I get an upgraded air cleaner I might invest in a an hour on a dyno. Either the SE Heavy Breather or a ProV Hypercharger.

Thats the question ive been interested in as well, thanks Oz.

would it pay to redo the Vtunes?

Thanks for your advice Ozroder, much appreciated.

Thanks OZ

I decide to redo my Vtunes as well, and all I can say is "it just gets better"

I had the CLB set at 700 for the Vtunes, went for a ride today with CLB set at 700, got home change CLB to 680 and now she just runs as smooth as.

 

Hi Guys

What is the general concensus on which air cleaner to upgrade to, SE Heavy Breather or ProV Hypercharger?? I am running V&H Big radius pipes.

Hi Guys I have set my CLB tables back to 700 and the decel popping has all but gone.
