When I bought my Scrambler and made the first 500kms, I wasn't happy with the throttle action. So I opted for the Boosterplug. And it worked absolutely as advertised. Smoother stationary running, a lot less jerky throttle action, and hardly any popping of the exhaust left.
Some 500kms later I mounted the G2 throttle tamer. That improved the throttle action even more, up to the point that the bike was now nice and easy to handle.

Although being very happy with the BoosterPlug and G2 throttle tamer, Rexxer tuning kept on luring in my mind. And when Rexxer lately had this €399-from-€499 action, I ordered the unit...

Well, that turned out the improvement I was hoping for! Most notibly: the way the bike now accelerates from 3000-4000rpm up - it's impressive. No stuttering, no lag, no holding back, it just takes off like a 'rocket'. The sound also seems to have changed while accelerating hard, more 'grunt' [by lack of a better word].
Secondly the engine runs cooler: it takes longer to reach normal operation temperature and is overall 5-10C cooler [reading from the oil temperature gauge I installed].
Don't know yet about the mileage/gallon but I would not be surprised that it is improved as well [when I can limit myself from enjoying the acceleration fun, that is...]

I guess the engine now is closer as to how the Ducati engineers meant it to perform.

All depends on the tune you go for. I can't figure out if the Rexxer + Decat exhaust has hurt my MPG, or just that I can't resist opening the throttle more now!
Certainly runs better though!

I have tried running 2 different maps that are intended to lose the CAT and the 02. With the less aggressive one I get about 52mpg average were as in stock form I averaged 56. The aggressive map is a bit mental and the mpg falls to around 47mpg. I have left it with the less aggressive map as it is still pretty awesome and not much difference in fuel usage compared to OEM

Forgot to mention that I'm running the bike without modifications, so stock exhaust, stock air-filter, O2 sensors present, etc. The mapping file Rexxer sent me is called "SCRAMBLER_800_15_16_".
And you will see this when switching the ignition on:

Hi Paul, I am glad you posted as there isn't any information that I can find regarding RexXer remaps and running the bike in stock form. This is what I am wanting to do in the medium term until I can get myself an aftermarket exhaust and race filter. Something I don't understand is if the O2 sensors must be disabled to improve fueling. You say you have the O2 sensors present but have they been disabled?

Disabling the 02 sensors is an option but it isn't required to see an improvement in fuelling. I've read just about every post I can about this and disabling the 02 sensors offers a bit more HP gain and also removes some of the popping from the exhaust. (Which I miss)

You're going to want your own unit if you plan on remapping before doing any upgrades to exhaust and intake. Rexxer provide two maps with the unit, so you could ask for one stock and then one to match whatever upgrades you plan to install.

I went with the cheaper option of the one time upload from a dealer, because I already had the parts on I wanted and they aren't coming off.

No offence but I highly doubt you are better qualified to tune the engine than Ducati engineers. Also cooler is not necessarily better.

I don't the impression anyone is making that claim. I completely agree with your sentiments (hence my fact finding and hesitation) but the Ducati engineers have to work within a parameter (legislative emissions standards) that aftermarket tuners do not.

Hi gcduc, I should have been more clear: the O2 sensors are present and enabled. The engine is completely in stock form [except for the Rexxer mapping now].
