Rexxer ECU Flash

I guess we just need to wait for some sucker, er uh I mean customer, to try this out and give us an un-biased opinion, so we can slice and dice it here on the forum I am sure he does great work, but I am still on my honeymoon (you remember, daily sex, etc), and cannot imagine this bike being any better.

P.S. Elite, great write up!

Thanks! I try to do my research before buying. Trying to give people some insight to common questions.

Can the Rexxer ECU flash be used as an alternative to Ducati's own UPMAP if you are fitting an Akra full system?

does Ducati provide a upmap for the AKRA? not to my knowledge...

Yes. IF....Rexxer has tuned several 1199's with the Akra exhaust and feels like they have a reliable map that will work for all similar 1199s. Canned tunes like the Rexxer are made by custom tuning bikes first and using those to create a generic map for a given mod combination.

As stated many times, the upmap is not a map. It switches the mapping already in the ECU to one that is better suited to the Termi. Think of it as a hardware based switch instead of Race/Sport/Wet it changes Stock/Termi Slip/Termi Full.

As stated in another thread, I have gone this route with both my termi slipons and now Akra full exhaust.

I have the user module so it was trivial to switch to the Akra once David sent me a new map. He did it very promptly.

My take is that there are some issues, at least on my bike, that need to be sorted.

1. The idle is to high. It idles between 1750-2100k.
2. There is still a dead spot/stumble around 4500rpm when getting on the gas aggressively. It is most noticeable in 2nd and 3rd gear. I have always noticed it on both 1199's I've owned but would expect it to be sorted with a custom map. The tuneboy fully fixed it but had other issues.

I have contacted David and he has assured me he is working on a new map to sort these couple issues.

Overall, the rideability down in the lower rpms is 100x better. I believe, after riding these bikes with many variations and attempts to fix the fueling, that this has been the best map I have used thus far. I much prefer it over the termi upmap with the slip-ons and feel that once the issues with idle and midrange stumble get worked out, I will be fully satisfied with this bike and my choice to use Rexxer.

So you are saying the full akra with rexxer is the best set up you've had on the 1199? Also it gives it the best mid range?

Thanks for your input re: the Rexxer. I have emailed David for some more info as to the suitability of the ECU flash with the Akra system and will wait to hear back from him, though your comments sound promising.

We went the Rexxer route with the racebike and Dave was able to eliminate a few things. Things such as the secondary air stuff and due to the fact that we eliminated a few other things. My builder was in contact with Dave and got him to eliminate codes that would be set off had they been used with the up-map.

A few things though... We had a VERY rich setup. Very. We got that sorted, but we still had some changes we wanted to make. These are changes that if racing, will be noticed. If street riding, the system is the bomb and most likely you will never notice these.

But, we had to piggy back a PC-V on top of the Rexxer to get the curve and mixture we wanted.

Two things. One, if using this for your street bike and aftermarket exhaust, you'll get solid gains. Second, however... If you are racing and running track, I would take the bike directly to Dave and have him build a map directly for your bike.

I like what they are able to do and we have had some success with the maps. We had a few issues going on that were bike issues, but we really had to convince him to lean the map out more than he provided.

Chad at Commonwealth took the Rexxer map and built a DynoJet map to go over top. The result was amazing and the difference was truly felt and better than ever. The result right now is right where I like it. I think we can dial it in even a bit more as the guys from Indy will be dynoing the bike and sorting out a bit of changes that I would like.

Overall, an "A" for the Rexxer setup. Racing just means you need a few other touches and unless you can drop the bike off, you will need a piggy back still. This is for VERY small and incremental changes that most likely would never be an issue on the street.

No your right they don't. Hence my asking about the Rexxer. I don't really want to go down the piggy-back route, as this was a real headache on my 1098S, even with a PC3. Ended up junking the PC3 and had a custom map made and a Nemesis ECU, which was much much better, plus selectable maps. Since MMS are not catering for the Panigale, Rexxer seems a better option with an Akra system, as opposed to shelling out for an up-map directly from Ducati, which is optimized for the full Termi system.

Lmfao!

Not sure if you have an up date, but I was on to David at Rexxer and he said that I don't need the Termi unlock key/up map key to use the Rexxer set up with my full Termi. Same should apply to the Akra I suppose.

Please correct me if I'm wrong but are the Rexxer set up and the Tuneboy more or less the same thing, very similar approach to the subject.
Obvious differences being Rexxer answer their emails and business wise are what Tuneboy could, should or will be.
The Rexxer is more expensive and seems a bit more restricted with their one bike license and credit system etc.
Tuneboy has cost and freedom on their side, if you can survive the poor before and after sales performance.

Anyone have any more insight, point out what I missing (pouakai, ES 357)

I think you pretty much nailed it, the only thing I would add is that if you have access to a dyno and intend to roll your own fuel maps then I believe that can only be done via tuneboy. If you are looking for canned/off the shelf tunes then Rexxer may be the safer choice...

Cheers mate, it does say on the Rexxer site (FAQ)

Q: Can I have my bike tuned on the dyno using my stock ecu?

A: Yes

It's a bit vague, not sure what exactly that means seen as how they want payment for subsequent maps (after whatever comes installed in the unit when bought) as opposed to free updates should anything better come to light, which I think is the case with Tuneboy. Not sure there would be much point going back to buy more if you can roll your own.

Tuneboy might be a better option for you.

Now 3 years later (since last post in this thread) I would like to hear experiences ans thougts from peoples using RexXer and Tuneboy. I will soon have to chose one of these for my 2014 1199S. I have recently purchased a new Termi full system without up-map and a sprint P08 air filter.

RexXer mapping I can get from an official RexXer point 3-4 hours away from me so that would be the easy choise with all possible support later if needed.

For Tuneboy option I have to order the model with keys and use a local tuner for dyno tuning. With Tuneboy option I would like the crise control option and the possibility to reset service lights also.

I just did Rexxer flash on my 1198 SP with the full termi's and it made a world of a difference ! Runs way smoother in every gear and the mid range pulls my arms off ! Every happy with their service .

OK! Thanks. 1198 is a complete different engine than the 1199 but for sure it will also improve the 1199 engine quite much. And I have to go either RexXer or Tuneboy route after installing the full Termi and Sprint filter. I guess both RexXer and Tuneboy will improve (smoothen out throttle and provide a bit more hp and torque ) the engine performance in a similar way but as always there are also issues reported as a side effect. I would like to go the route with less troubles in the long run…

I am still needing to have my rexxer tune modified...

I bought this earlier in the year, and to be honest have not been very happy with it, except on the racetrack, even though my dyno numbers with it seem a bit low.

Being a mail order flash, I did not expect perfect but my fueling under 6000rpm at anything other than @ 40% is not so stellar... God forbid I am in 6th gear at 4500-5500 and try to accelerate, the bike feels like my old 1098 at 2500rpm.

The termi slip on upmap was crisper and smoother, even running the termi full system, mwr air filter and pair block offs.

thinking I will have him flash it to Stock full termi upmap, and then add a rapid bike.
