The FMF Power Programmer is a rebadged EJK FI Programmer, so the settings are the same.

Here are some of my notes. 

1000ft elevation & hot Texas weather. 

EJK set to 1.5, 2.0, 3.5 - 4/29/16 (airbox)

EJK set to 1.0, 2.0, 3.0 - 4/30/16 (seemed rich)

EJK set to 1.5, 2.5, 4.5 - 5/4/16 (pipe)

Test EJK settings to try:

( 2 / 3 / 5.5  * 5.5 / 3.5 / 4.5)

Here’s a great thread in this forum on the EJK/FMF.

And finally more notes I took from another post years ago:

EJK settings bottom line IMO: Explore what works for your engine, riding preference, and economy vs power desires. 

 

Dobeck's default settings for stage one produce more power than lower numbers. They are not 'too rich' as some suggest, but they do produce considerably more carbon buildup in the exhaust and spark arrestor. choices and consequences. 

 

Lower numbers provide greater economy at the expense of some power. I prefer optimal power without being silly or wasteful, so my 'current' (I play endlessly with the EJK) settings are: 

 

2, 3, 6, 4, 3, 3.5. My cruise 'Green' setting is reduced to 2 to improve economy without noticeably reducing power. The switch point (last 3 numbers) are reduced from Dobeck's defaults to kick in the added fuel (first 3 numbers) just a tad sooner. That improves throttle response, assuming you've got things tuned well enough to cope with that. You can to 2.5 on the blue/yellow and blue/red, but don't go below 4 on the blue/green switch point (it can cause stalling at stops). 

 

My performance mods are:

 

-- 2.5 inch I.D. custom fab'd snorkel

-- K&N air filter

-- Full Yoshi RS-4 Comp Series exhaust with spark arrestor instead of low volume insert, plus a custom fab'd decibel reducer.

-- Completely removed the PAIR system

-- Gearing: 14 tooth drive and 42 tooth driven

-- Krieger manual CCT

-- O2 Sensor is currently 'connected.' I have explored disconnecting it many times. Disconnecting improves low end, but at a cost of 3 - 4 mpg (imperial). If you disconnect the O2 Sensor, you should tweak the green and yellow fuel settings, and also the blue/green and blue/yellow switch points to get the most out of it.j
