How do I autotune?
To Autotune your map, you must first flash a base map onto the bike, the closest V&H map to your configuration would be ideal. Then, select Autotune from the main menu and select ‘Quick Setup’. Next, choose the map slot you would like to base the Autotune off of. This will initialize the Autotune process by flashing the bike. Now, go out and ride. The more varied types of riding you can do (stop and go, steady-state, uphill, downhill, low rpm, high rpm, low and high throttle ranges, etc.) the better.
We recommend 3 sessions, each approx. 30-60 minutes in length. ‘Apply’ the data after the 1st and 2nd session, ‘Finish’ the Autotune after the 3rd session. During Autotune you may experience issues such as poor cold start, poor throttle response, and general ride quality issues. These will resolve once you ‘Finish’ Autotune and the map is re-optimized.
How do I edit my map for camshafts and engine modifications?
At this time the Vance & Hines FP4 does not support camshafts or big bore kits, but stay tuned
Does the Vance & Hines FP4 marry to the motorcycle's ECM?
Yes, once a Vance & Hines FP4 has been used to flash a bike it is permanently married to that ECM. You can use the same FP4 on other bikes to read/clear trouble codes and view live sensor data, but will not be able to flash a different bike.
I'm getting a U0100 error code after flashing with the Vance & Hines FP4, is this normal?
Yes, the U0100 trouble code is a historic trouble code that occurs when flashing the ECM. You may have one or several after flashing, which is completely normal and will not trigger a check engine light. You can periodically clear these codes out through the FP4 app if they occur.
Does the Vance & Hines FP4 have to stay plugged into the motorcycle or can it be taken off?
The Vance & Hines FP4 may be removed from the motorcycle once the map has been flashed to the ECM. For Live Sensor Data and Diagnostic Code reading, or any other map editing or viewing, the FP4 must be plugged in, and your smartphone connected by Bluetooth.
