Monster 1100 Evo ECU reflash

chris.p · 18-10-2014, 07:16 PM

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.

(I can not upload the chart for some reason, will try to add it later)

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 36-38 mph.

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

A big thanks to Neil at Cornerspeed

That sounds just what I'll be looking for in the future.
Only problem is I'm in Scotland

Anyone know if there is anywhere in Scotland that can reflash a 796 ECU???
cheers

Cheers Chris, just seen the same post on the DUN site!!

chris.p · 19-10-2014, 11:06 AM

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.

The Ducati' performance kit installed and I was advised that my 1100ds was running too 'lean' and all the same issues that you describe. I thought that the performance ECU would sort it out but it just made it worse.
I had a re-map the sensors and exhaust valve removed. This sorted the fuelling problems and now the bike runs great!
Headline figures for my engine taken at the rear wheel:-
Power 86 bhp @ 7286
Torque 62 ft/lb @ 6250
AFR (Different for front and rear cylinders) F 13.23 R 12.98

I would be interested to see your dyno chart (I realise the engines are different)

chris.p · 19-10-2014, 01:08 PM

Hopefully one of the links should work.

Blue is DP ECU.

Red is DP ECU with Rexxa flash with lamba sensors and valve disconnected.

One thing that sticks out is that with the Rexxa flash, you are can open the throttle before 2750 rpm compared to not being able to open the throttle till after 3250 rpm :-)

Darren69 · 19-10-2014, 01:26 PM

The DP ECU generally suffers the same leanness issues as the standard chip (at least on my S4) and so fitting open pipes etc, generally makes the problem around 3000 rpm felt more. Re-map or PCIII is the way to go, that's all Neil did to mine. Well I told him to concentrate on the low 2-3k rpm delivery, but he knew anyway so that's where he spent most time. Totally transformed the bikes behavior and is now so smooth and well behaved at town speeds its a pleasure and so much easier to ride in traffic.

holty · 19-10-2014, 01:34 PM

Thanks,
Very similar results which is of interest.
I forgot to mention I run the standard 15t gearbox sprocket. I have covered over 10k since modding my bike and it runs very well and the only trade off is about a 5% increase in fuel consumption, but that's small beer for a 'sweet' engine.
I have been advised that now the AFR is correct there is less or no chance of burning out the exhaust valve which is a common problem with higher milage DS motors.
It's such a shame that to get the motor running correctly that you have to through a bit of time and money at the problem.

Darren69 · 19-10-2014, 02:27 PM

its to do with EU emission regs. apparently, so the bikes are deliberately set to run on the lean side about 3k rpm so they can pass the test, putting open pipes and filter just makes it worse!

Darren69 · 19-10-2014, 02:31 PM

Altering the gearing may be a work-around of sorts but the problem will still exists, you can just move it out of the rev range that you use most in town.

holty · 19-10-2014, 03:55 PM

That's right; emissions regulations are the route cause. I presume that this one of the many reasons that the much loved air cooled Ducatis have finally been replaced with cleaner more powerful but more complicated water cooled versions.

MerlinPV12 · 20-10-2014, 09:47 AM

Hi Chris,
Just for comparison I have had my 1100 fitted with a Bazzaz and HM quick shifter. No base run was done on the DP ECU, just a first run with the Bazzaz on top. Looks like both our efforts have produced better bhp and better running bikes! Mine is on a 15T front and 42T rear.

The second graph is the gear change speed diff between hand clutch and QS. Despite having seen the graph before I rode the bike, I didn't think it was going to make that much difference in "real" road riding. In the brief time I've ridden since having the work done its made a big difference. The HM QS is so smooth its a joy to use, even on a run down to the shops! Steve and Tony did say they had a "bit of fiddle" getting it set right as the gear change mech is quite stiff. The other point they mentioned is that the bike was running very rich when they first had it in with the plugs being jet black....

Overall very pleased with the transformation at low speed and listening to that "blat" from the exhaust as you snick the next gear is addictive!

Blue is hand Red is QS

Merlin, that's a much better dyno graph, much smoother, than Chris's.
I had an ECU remap a couple oif years back and had very similar results to yours.

holty · 20-10-2014, 07:30 PM

Hi,
With regard to the quick-shift; I wanted to have one fitted but was put off because I was told that unless that particular model has the option of the QS then don't retro fit one? The reason being (information given to me at the time) gearbox failure. It would appear bent selector forks are common with this up-grade.
This information maybe total rubbish and like you say everything is sweet, but it was enough too put me off for now.
Interested to hear what others have to say.
