Thank you Terry!!!

I contacted Fuel Moto by e-mail last night about the availability of a map for my Heritage. They replied that I would get better throttle response and cooler running. I wasnt the cooler running because when I bought the bike it had the V&H Big Radius 2 into 2 pipes and the HD SE Heavy breather intake installed with no fuel adjustment.

The one thing I forgot to ask them was about fuel mileage. I am pretty well set on ordering this unless I would take a big hit on fuel consumption. In the old days when hopping up our cars we would put headers and larger jets in our carbs and as a result get we would get better gas mileage as long as we drove it right. Am I wrong to think this should apply to my bike as well?

Has anyone using this product and not hot rodding it checked their mileage? A comparison of before and after using similar riding styles would be great.

iclick you need to use the data logging to properly calibrate the map to your actual equipment. Once this is done if you set a target of say an AFR 13.9 you will actually produce 13.9. I don't have the time to write it up right now but this is exactly why I bought this unit over say TTS Mastertune. Both accomplish the same thing but this unit is a lot more interactive and you don't have to drag a laptop around to perform your data logging to get your calibration points correct for the way your motor breaths. If you perform the data logging and adjust the tables properly your tune will be dead on the money without using a dynotune.

Their maps have gotten more mileage-friendly over the past few years since gas prices have become a fluctuating issue. Their tunes will likely not produce quite the mileage you realized when stock, but probably close enough. I would ask them to tweak the tune for better mileage, as they can do that. My experience is that lean AFRs aren't the bugaboo that many of use have thought in the past, and I've been running 14.6 in the cruise range with no heat issues. I also installed an oil cooler, which helps greatly to keep peak oil temps in control.

How and where you ride is important. I do some hypermiling, like coasting as much as possible when stops are imminent, and find that a steady speed will get you maximum mileage, falling off as you change speeds frequently. My highway mileage is very good, upper-40's usually at moderate speeds, but nothing I do has gotten my city mileage where I want it, which is usually in the mid-30's. E10 gas doesn't help, and that's about all we can get locally.

It doesn't matter what tuner you install, as the map or tune is what dictates your gas mileage. Anyway, here's mine, which hasn't changed since moving from the PCV-AT.

Highway, 50-55mph: 47-49mpg
Highway, 60-65mph: ~46mpg
Highway, 70+: 45 ±1 mpg, as low as 40mpg with a strong headwind.
City: 35 ± 2mpg.

I'm not one complaining about my tune, as I've done quite a bit of datalogging already. I also haven't touched my tune since I'm happy with it. I auto-tuned with the PCV-AT for two years and was happy with mileage and performance, so I imported the PCV map when I installed the PV. All is well.

I will be experimenting with the PV Log Tuner, which is now in beta, but I'll need to obtain some wiring for my AT-100 first.

Net effect using one of Jamie's maps is that you will either pick up a little HP or a little more gas mileage because it will be spot on vs close to what he tuned on the dyno. It just dials the map in for mechanical and sensor variation on your particular bike. The easiest way for you to understand what I am talking about is to read the TTS Mastertune documentation. This unit does exactly the same calibration and the data logging is how you gather the information to dial in the map. So say Jamie has calculated you should be running at 13.2 in one particular cell maybe your bike is running at 12.9 with the map. After applying the data logging information to the correct table you will be running at 13.2. It's been a couple of months since I read up on all of this but it's just calibrating so the maps are spot on vs kind of close.

BTW: It's good to know your fuel economy is so good. You and I run pretty much the same setup. I didn't go to the PCV when you did, I stayed with the PCIII and jumped to the Vision.
