I was told to wait until the next day between the heat cycles. So with three heat cycles, that is three days right there before you even think about a ride. I would do that for sure before a ride or a Dyno tune, good luck.

^^^^This. They can also stop and "fix" something if needed. curious though, can you actually calibrate the ve tables with Target Tune?

That is a good question that I will bring up with the shop. Use of the target tune, from my perspective, isn't a must. It is a carry over from my totaled '15 Ultra which was totaled and I took it and the PV-2B off prior to turning over the bike. I had them re-licensed and if the target tune isn't needed, then I won't install it.

This is straight from Dynojet's website:

"Utilizing the Target Tune AFR data and other data from the H-D ECM OEM data bus, the Power Vision can automatically fix the deviation between the AFR or Lambda as defined in the fuel table of your calibration and the actual AFR or Lambda by adjusting the VE tables."

You may want to explore the option of having it dyno tuned at DC Cycle and Racing by David. They are in Red Bay, Alabama, not that far from you in Memphis (around 2 hours)

I believe you will be much happier with him than either of the Dealerships you mentioned (I have used all 3). Plus, there is a good chance that David will be less expensive.

David is a very helpful guy, and is who I would ask about your questions.

I am hoping to finish my TC 110" build in the next month or so depending on parts and time and then heat cycling it, checking for leaks, making sure it actually runs, etc. But then it's going to sit for a min until I get it out to FuelMoto on Apr 3rd. I don't really have much of a choice since I'm not bringing a new build 4.5 hours away without even knowing it'll run, and I can't wait till the last min to heat cycle in case something needs fixing.

I wouldn't think it would matter how long it sat after the final heat cycle either, but I'm willing to listen to people that might know more than I do. For the record my shop is heated/cooled and I run a dehumidifier over the winter to keep any moisture that comes in with the cars down to 45%.

EDIT: FuelMoto is doing the break in and tune on the dyno for me.

Thanks for the feedback and insight. I spoke with my tuner this morning and as you noted above, he also said to go ahead and heat cycle it 4 times to ensure everything is running smoothly and that there are no unresolved issues from the build that would impact him performing the tune.

Good news. I forgot to mention that when I called FuelMoto to book my session Tony also said the heat-cycling and waiting made no difference.
