Default FP3 Tuning Parameters

So folks, after waiting and saving, I have upgraded my 2015 RK to slip on Crusher mellow slash-cuts and a high flow AF as well as invested in a FP3 tuner. I flashed the bike with the file recommended by V&H (for the record, the FP3 is the most amazing bit of kit I have ever seen. I work in diesel product development and similar tools run into the thousands of dollars).


Anyway, I have read the posts regarding using the pre-defined maps or starting with a map and then using auto tune. While the debate seems endless, what I am missing is what performance parameters do people recommend to compare to decide whether a defined map is better or worse than an pre-defined one. For example, would the experts out there recommend that you use fuel economy, max engine temp, and torque as the three comparison points between the potential maps to then pick the best.


Just looking to understand how to pick the better of the two options without relying on just seat of the pants experience.

The FP3 is a great tool. Easy to use and has lots of great features including speedometer calibration. You can use a canned map which there are many of them available and then go into auto tune to refine it; not required but it's there. You can then save that auto tune and go back to the canned map to see which tune you like the best and then run with it. Auto tune monitors your O2 sensors and will adjust your VE tables accordingly which effectively changes your AFR at each RPM and throttle setting. Once programmed, you can remove the FP3 from the bike or if you leave it in you can view many of the gauges available on your phone.

Hello, with the mods in our application I would start with the FP3 base map for the Stage 1 air cleaner and V&H Monster Round mufflers. This will be a good starting point.

Jamie - thanks for the response, this is the exact map I used after contacting V&H customer service. Great service, great response, and from the first 100 miles, spot on recommendation.


The FP3 is a powerful piece of internet enabled wizardry that really puts the whole vast set of tuning knowledge from V&H onto your phone and hence onto your bike. Its so simple to use, honestly, my 10 year old could figure it out (hence it took me twice as long).


Either way, my current plan is run the pre-defined map for a few hundred miles and check outputs like engine temp and fuel mileage since I feel these two parameters are the best measure of overall engine tune - engine temp will tell me if the mix is rich/lean for my driving duty cycle and fuel economy will tell me if I have a good match of throttle position to load (not too much, not too little). I will then repeat the process with auto-tune. Luckily I use the bike as my daily transportation much of the year and thus my driving is highly repeatable from day to day.


Let the best map win!

One thing to be aware of with the FP3 at least for me, during the Auto-Tune segment my mileage went to hell. At first I was disappointed until I figured out that once I burned the finished map to the ECU the mileage went back up above 40mpg. During the Auto-Tune segment ("I think") there is a lot of extra fuel going in to bike to sample the end results with the O2 sensors or I was just riding more aggressively to fill more cells with data!.

I've really been looking at getting an FP3 myself. My problem currently is I can't seem to decide on which header to go with. I have V&H Twin Slash slip ons and have been thinking about changing those as well.

Sorry to hijack!
