Which is the best setup for Vance & Hines FP3 with Red Thunder 2:2 touring exhausts?
Let’s say… you have at least Stage 1 (air intake + exhaust) on your Road Glide, then the next step is to remap the factory mapping.
You can use many alternatives, some of which might be done by your dealer, while this article covers probably the most famous unit available in the market for almost all models of Harley-Davidson with a comprehensive and dedicated list of exhausts from all brands. You don’t find your brand? Well, V&H will tell you which map to use!
My performance accessories are:
- Air intake: V&H VO2 naked
- Exhaust: Red thunder 2:2 with slip ons
- Spark plugs: NGK iridium IX
- Spark cables: Sumax 10.8mm
- Battery cables: Sumax extreme duty
Which is the best map available? This one: Vance & Hines Monster Round slip ons w/Power Duals standard baffle
Then, what about “Decel pop“? Leave it OFF to have the max Pop from exhaust!
What about throttle progressivity? For the 2020 model, does not apply as the bikes ship from the factory with 1:1 settings already (equivalent to our Race 1:1).
Next step? Start and perform autotune! Follow these steps
**Be advised that while Autotune is active the bike will not perform optimally. The AFR table is not optimized, and the cranking fuel/accel enrichment are turned off. This may translate into poor cold start performance, erratic idle, poor throttle response, and general ride quality issues. These will resolve once you ‘Finish’ the Autotune. Letting the bike fully warmup before riding while Autotune is active will help to slightly diminish some of these symptoms.
1) Go to the Autotune tab in the main menu of the app.
2) Select a base map from which to start (select whichever slot your correct map is in, most likely slot 1 if this is a brand new FP3.
3)Select ‘Quick Setup’
4) It will have you flash the bike to run Autotune, follow the in app instructions (i.e. bike off for 30 seconds, etc.)
5) Once Autotune is active, you’ll want to break it down into 3 sessions, approx. 20-60 minutes each.
6) After your first 20-60 minute session, open the app and go into the Autotune section. Select ‘Apply Values’ and ‘Apply’. This will take the data learned and store it, allowing for more data to be collected.
7) After the second 20-60 minute session do the same thing – ‘Apply Values’ and then ‘Apply’.
8) After the 3rd total session, select ‘Apply Values’ and then select ‘Finish’. This will complete the Autotune, taking everything learned from each ‘Apply’ and will build the map/put it into a new slot.
NOW, enjoy your bike!
