REXXER problems - help!

[desmoworks]

for the computer changes he is doing... how much?

I'm assuming: closed loop elimination, RPM limiter change and DP map? or is there something more?

Was this question for me? If so, he is making complete custom maps for each exhaust system and any other setup that need be. No DP maps as he is using a PCV. So yes, open loop, can change RPM limiter if need, custom fuel map and custom ignition map.

The MTS1200 PCV is $499 as it has a custom setup to eliminate the O2 sensors as the MTS ECU is more complex than Marelli and Siemens. I'll have to get the pricing on the Monster kits from David as we've only been working with him on the MTS kits thus far since there are other alternatives for all Ducati models besides the MTS1200! Now we have our cable to flash the Siemens ECUs with Rexxer maps. We charge $249 for that: http://www.mota-lab.com/ducati-ecu-reflash-p-463.html

Here is a bit of info on what he does on these custom PCVs: http://www.desmoworks.com/index.php?main_page=product_info&products_id=738

I'll have the Monster kits up and available at the start of the week.

I guess Rexxer hasn't got it sorted out yet.

Rexxer still doesnt have the service reset feature sorted out  .  Chris from Rexxer said that they'd have the service reset function.... um.... functioning "by the middle of December".  Although he didnt actually say by which December.  Chris? 

We are working as the West Coast sales point for David's specially setup Power Commanders (he is handling sales on the East Coast). We can supply PCVs for every current Ducati including the 696/1100 as well as the MTS1200. All with full open loop maps!  

How does a PCV eliminate the Siemens ECU's closed loop??

...for anyone who is using Rexxer and wants complete open loop no o2 sensors and no error codes I found a guy in the US that can fix that problem and for those who are planning on a reflash or PCV for the 696/1100 I would talk to these guy's first as they seem to have completely figured out the Semiens ECU.

Maybe, but "seem" is the operative word there.  Talk is easy, Rexxer too believed they had it right but have discovered its not so easy to crack as first thought.  But they have not walked away from the challenge and whilst they have not had much to say about their progress, some progress there has been.  I guess they dont want to announce anything until its certain that they have it right.

Rexxer is very close to having the o2 error issue figured out.  Chris has been sending me modified versions for testing and I no longer get any check engine light..... just a little more fine tuning and I think they'll be able to announce that its completely sorted.  I have no affiliation with Rexxer and as you all know I have been critical of em in the past..... but I have to say that they have been extremely busy in the background working to fix the o2 error code issue.  When they finally get there (as I'm confident they will) it will be tried, tested and proven.  By me (and others too, so I'm told)  .

It can't, I believe you need to send him your Siemens ECU He has cracked the Siemens ECU and will program them out this is for the 696/1100. His kit for the Multi is complete plug & play the way He did it on the Multi is by tricking the temp sensor to think it's 28 degrees all the time so the o2 sensors never come on you can leave hooked up or remove them from the bike so complete open loop, some part He sends with kit does this.

I agree, and I haven't used his product yet. but I know his PCV works on the Multi as I posted. I have some correspondence with Him and the guy "seems" very honest and has been in the racing community for years it turns out we have a mutual friend in the business so I highly doubt He is BS. I just posted up to let people know there is now another option for the 696/1100. I can only suggest guys  contact Him and talk it through to make sure your getting what you want as having complete control over your ECU mapping with a PCV IMO is the best option there is. I'm done with the 696 and still real happy with the Rexxer mapping. So it would be nice to have someone with a 696/1100 try this guy out & post up results.

Oops, sorry - that is only for flashed maps, not the PCV maps!

[ungeheuer]

....Kinda figured that  .  And you're using Rexxer hardware/mapping for your Siemens ECU reflash service or something new?

....he is making complete custom maps for each exhaust system and any other setup that need be. No DP maps as he is using a PCV. So yes, open loop, can change RPM limiter if need, custom fuel map and custom ignition map.

Still confused here.  He is making custom PCV maps for each exhaust system, but also reflashing the Siemens ECU to delete closed loop?

I am in no way calling BS on your guys ECU reflash option either.  Just saying that until I've seen evidence that it ticks all the boxes I'd prefer to reserve judgement.  Has he tested on Siemens ECU bikes and confirmed that the ECU does not flag any error messages when the Lambdas are disconnected/removed?  See the reason why I am so particular on this issue is that Rexxer were also confident that their reflash deleted the open loop entirely too..... and eventually it will, but not without a lot more mucking around than was first suggested.  So anyway.... rather than completely reflashing the ECU... it seems that your guys method is to trick the ECU into not referencing the o2 sensors thus allowing his (or anybody's for that matter) PCV mapping to be effective across the entire range? 

And FWIW I dont agree with you regarding having a reflashed ECU + PCV as being the best option (even though this is the option I myself chose to run), its only second best.  IMO the best option would be to have your ECU flashed with custom mapping perfectly tailored to your requirements/bike without the need for any piggy-back device making after-the-fact corrections.  Trouble is its difficult to arrive at that "perfect" map without an easily reprogrammable add-on device like a PCV.

Hey Desmoworks!
I've attempted sending you emails and PMs. I'm afraid they're not getting through. Let me know!

Thanks!

The latest mapping I received from Rexxer fixed the o2 error issue  .   No more "lambda slow response" errors and no more accompanying CEL .  Me happy, thanks Chris .

Now... just need to be able to reset my "service due" indicator and the Rexxer will finally be everything it promised to be in the beginning  ............

Its been a long process.

[Desmotwinrider]

You are right..."a long process" but "Good things take time"  as I have explained several times...
About the update for the reset of the error codes...I know you are waiting for us once again but it's not so easy as we thougt...so it will takes a litte time longer but I promise it will comes! The same as the complete elimination of the O2 sensors...it takes time but in the end all will be well  

I will keep update you all if I have any news! Rome was not built in one day  [moto]

Cheers Chris

PS: If everybody has already installed a RexXer Mapping without completly eliminated O2 sensors but ordered this service, please contact me directly via mail (cs@daniele-moto.de), I will provide relief.

Warten, warten, immer noch warten  . 

Are we there yet?  My friends keep laughing at the spanner icon on my display  .

Are they laughing at you because of the spanner icon....or because your avatar looks like Dr Zachary Smith?

Many months have now elapsed since buying my Rexxer unit.  Whilst the issues with deleting the 02 sensors were eventually dealt with, Rexxer users continue to wait for the release of a firmware update which allows the Rexxer unit to reset the bike's "service due" indicator.  

When I (and others) bought the unit we were assured this feature was functional. (Although there's no way to know until you attempt - and fail - to reset your service indicator when it's displayed).

When I (and others) pointed out to Rexxer that the service reset feature DOES NOT function we were told it would be fixed.  By mid-December 2010.  Then when that time frame came and went we were told "these things take time....."

Well I'm frankly sick of waiting. I urge anybody who has purchased a Rexxer unit to contact either Chris Schimmelschmidt or Marco Daniele directly and demand that they reslove this.

And whilst we continue to wait...... I notice their website continues to claim the Rexxer unit is able to reset the service alarm for Siemens equipped Ducatis >>  http://www.rexxer.eu/e_rexxer.cfm  <<  At this time, any such claim continues to be absolutely FALSE.

Email to Christian sent, I thought I read a post where Christian/Rexxer said they would "take care" of anybody who paid for that function, I thought that meant some sort of refund or something along those lines. Or maybe that was a different problem then this one, anyway I think a little pressure from the members of this forum got Rexxer to fix a few other bugs in the unit so hopefully Rexxer will deliver the goods.
