My Suzuki M109R ECU programming (Re-Flash) includes the following:

My exclusive software & tuning experience offers you the best result possible.

This offers you the most refined feeling, smoothest, most powerful, best driveability, best fuel economy

than you will find in any other ECU flash offering for your Suzuki M109R.

1) Fix all fueling problems inside the ECU.

(The ones that cannot be fixed with an external fuel tuner or other commercially available methods)
a) All gear dependent maps equalized
b) Main fuel tables (A/n) - adjusted specifically for your exhaust at all active throttle positions.
c) Vacuum tables (MAP)- adjusted specifically for your exhaust in all active areas.
d) Emissions compliant sub-routines that affect driveability - turned off.

e) All response delay filters (detuning items) - turned off.
f) Deceleration tables thoroughly tested and re-adjusted for best closed to part throttle response.
g) O2 sensor disabled - No need to unplug, or can be removed if desired. (2006-2009 US models)
h) Torque limiters turned off.

2) Disable fuel cut - ie; Jerky throttle
Don't know what "fuel cut" is?

Live datalog

Live datalog Disabled:

3) Complete custom re-curve of ignition timing
a) Gets rid of part throttle timing retarder for more response and less vibration when cruising and moderate acceleration.
b) Gets rid of high rpm timing retarder allowing the engine to make maximum power for longer.
c) Set timing for maximium power and driveability across the entire rpm range & all throttle positions
d) Adjust timing to be the same for all gears - No TRE needed.

4) Reduced heavy engine braking on decel.
(More relaxed gear changes and throttle modulation at all speeds - in all gears)

5) Re-program Sub-throttles for best response and remove power restrictions

a) This allows a more sensitive throttle that is easy to control.
b) Allows 100% of the M109R engine's available power - whenever you ask for it.
c) Gives immediate engine response to the throttle with no restrictions

6) Low gear power limiter removal
- No TRE needed !!
(Turn off torque limiters - separate item from subthrottles)

7) Remove top speed limiter - No TRE needed !!

8) Reduced running temperatures

9) Cooling fans come on at 200 degrees
(Helps keep engine cooler when you are stuck in traffic)

10) Raise rev-limit to 7500 rpm - adds another 300 rpm of hard pull in each gear.

11) SET valve code removal - No exhaust servo eliminator needed !!
a) Done without disabling the rest of the bike's self diagnosis

b) Your bike will still display trouble codes if a problem arises just like it does now)

12) Close PAIR valve - No block off plates needed.

13) Answers to all your questions.....

14) Anything that compromises performance and/or driveability is eliminated.

15) Free updates when/if we make improvements.

16) Return your ecu back to stock at no charge for any reason.
    (shipping not included)

PC3, PC5, or PCFC or other fuel tuner not needed

All testing was done in house on the above M109R's

Dyno tuning not necessary

We can reprogram for the following markets:

USA & Canada for now

ECU reprogramming may not comply with federal safety/emission laws
ECU reprogramming may not comply with your warranty

See dyno charts below

5th gear speed limiter test - This bike is limited to 125 mph with it's original ECU programming.

Intake test w/stock exhaust - Stock intake vs. Big Air Kit (BAK)

The Tri Pro 2-1 exhaust power potential is a little deceiving due to it's internal baffle plate helping to keep things quiet.
See chart below this one for results after it's removal.

Cobra Tri-pro Baffle test

Cobra duals vs Cobra Tri-pro 2-1 w/ baffle plate removed - The 2-1 now makes more peak power as it should.

All Stock M109R vs. Cobra Tri-pro 2-1 w/ baffle plate removed

All Stock M109R vs. Cobra Duals
