Hi guys, I trust everyone has enjoyed a fabulous riding season.....I get calls and messages all the time from folks who just can't seem to get their 1800's to run properly after they install pipes and an air filter mod (big gains are to be had here if the flow is right) along with of course a PC3.
After thousands of hrs tuning my VTX 2000cc high compression, Chromeless Cruiser and other 1800's, I'd like to post a very simple map for you to enjoy and share. This map will eliminate all deceleration popping, allow the motor to run much smoother and produce max power. This map is called a "smoothing" map, it effectively turns your FI Honda into a carbed motor.....BTW - There is no need to plug in random numbers all over a PC3 overlay map grid, under acceleration the FI system can't keep up and it will naturally 'smooth the map' on its own, so why not just make it simple. Tried trued and tested, here it is:
0 2 5 10 20 40 60 80 100
500 10 10 10 10 10 10 10 5 0
1000 10 15 15 15 15 15 15 5 0
1500 10 15 15 15 15 15 15 5 0
2000 50 20 20 20 20 20 10 5 0
2500 50 50 20 20 20 15 10 5 0
3000 50 50 50 20 20 15 10 5 0
3500 50 50 50 50 20 10 10 5 0
4000 50 50 50 50 50 10 10 5 0
4500 50 50 50 50 50 50 10 0 0
5000 50 50 50 50 50 50 5 0 0
5500 50 50 50 50 50 50 5 0 0
6000 50 50 50 50 50 50 5 0 0
Note - The 50's are all in the overlay maps 'deceleration curve', you never ride or accelerate there without hitting the rev limiter, so don't worry about it, this extra fuel flow smoothes out the 'on off' throttle condition of a stock FI motor and removes all decel popping by creating a 'too rich to burn' condition in your free flow pipes.
If you've installed aftermarket free flow pipes and an aftermarket free flow air filter or breathing system (BTW this in where the most gains come from on a stock VTX) this map will do wonders for your motor, your riding buddies and the general public! Depending on the degree of your mods adjust the map accordingly - FYI, my beast runs 10-15 numbers higher across the board.
All the best,
