Monster 1100 Evo ECU flash
 

After having fitted a set of termi's to my 1100 Evo and hearing that Neil at Cornerspeed in Kirkby in Ashfield can now flash the Siemens ECU, I duly booked her in for this morning.

Neil does a couple of runs on the dyno (he has his own Dynojet inhouse now) then to get a base chart, then gets the Rexxer kit out and downloads the map for your bike with std or race cans etc.

Once the ECU has been flashed and checked he then does another set of runs on the Dyno.

As you can see from the attached dyno chart, the bike gains every where, what you can't see on the chart is the difference this flash makes to the bike.

This is what i found on the ride home.

Points as follows. (Remember, I am running a 14th front sprocket)

Pulls cleanly with no hesitation in any gear.

The bike does not hunt on part throttle, smooth at all times.

Acceleration is just awesome :-)

After coming fast and hard down the gearbox into a slow corner, throttle response is instant and without hesitation on exit.

Pulls from 3000 rpm in 6th with no hesitation.

Pulls from 2500 rpm in 4th with no hesitation.

Pulls from 2250 rpm in 3rd with no hesitation.

I did not get chance to take it into town, but in 3rd at 2250 rpm, the bike sat at an indicated 36-38mph

Is it worth the £285 cost, damn right it is

A big thanks to Neil at Cornerspeed

Have just done a ride around town, all the lumpiness has gone, just so smooth, in 3rd it pulls from a fraction over 2000rpm (approx 24mph)with ease, it pulls from around 2300 4th (approx 30-32mph) with ease.
You can easly tootle along at 30mph in 4th with ease in town.
Overall the Rexxa flash has made the bike so much easier in town, no lumpy judderings at all, a total revalation compared to standard, msy even put the 15th front sprocket back on and see the differance.

Has yours got the exhaust valve? There's a dip around 5500rpm in the torque and this is the noise test reading where the exhaust valve does its stuff, so I reckon if you junked that it would take the dip right out!

The Rexxa flash disables the valve, (also the lamba sensors are now disconnected), so it always sits open, you can not feel any drop in torque, it just pulls hard as soon as you hit the throttle :D, the difference compared to before it went in is awesome :D

Sounds good. :)
