Siemens ECUs - the reflash/modding possibilities

[ungeheuer]

Maybe it helps to make things more clear for each of us if we take a look at my options:

Option A: Do nothing more.  So, leave my DP "racing EVO" ECU stock, leaving the Lambdas with Powercommander o2 optimisers to continue to manage in the closed loop.  Run with the WASP created "off-the-peg" PCV mapping.  The bike runs well like this (although I dont KNOW for sure exactly how well the WASP PCV mapping is matched to my particular setup).  For that I'd need to go to Option B.

Option B: (Now abandoned) Was to leave my DP "racing EVO" ECU stock, leaving the Lambdas with Powercommander o2 optimisers to continue to manage in the closed loop. And put my bike over a Dyno to create PCV custom mapping for the open loop area.

Option C: Reflash ECU to remove o2 inputs thus deleting the closed loop.  Dump redundant stock o2 sensors and "optimisers".  And put my bike over a Dyno to create PCV custom mapping over the ENTIRE range.

Option D: Reflash ECU to remove o2 inputs thus deleting the closed loop.  Dump redundant stock o2 sensors and "optimisers". Figure out how to adapt the PCV dual wideband o2 Autotune option (version AT-100) to build dynamic custom mapping.... over the entire range.

Option E: Reflash ECU with Rexxer-written custom tuning map, based on their best estimate of whats needed to fuel my WASP intake mod and Termi exhaust combo.  Dump redundant stock o2 sensors and "optimisers".  Dump PCV. A tidy solution, but no way to measure the outcome without visiting a Dyno.  And then - unless Rexxer hit it perfect first time - I'd need to go back to Rexxer to ask for ECU mapping to be modified based on Dyno results.  Could take several Dyno visits/Rexxer remapping to get it just right.

Not available to me, but for those who live in Europe there's also another option:

Option F: Visit a Rexxer Tuning Centre and have them reflash the ECU with a custom tuning map created using their Map Editor software based on their Dyno results for your bike.  This IMO would be the best option of all, after all what you would end up with is an open loop ECU mapped for optimum performance for your setup.  No "piggy-back" PCV.... No o2 sensors...  

This process is not that different to the PCV tuning session you'd get at your Dynojet centre EXCEPT that Rexxer are "tuning" the ECU mapping directly, rather than modifying the ECU mapping though an "add-on" unit.

Seems that for me the most sensible options are either Option A (after all its already fabulously better than stock)..... or to go to the next level, Option C.  But being sensible is not always what motivates me.  I wanna know if I can make the Autotune setup work, I like the tune-it-as-you go, user-inclusive modability this seems to offer. I believe it can be done and so its as much about the process of finding out how as the end result.  I know.  I'm my own worst enemy  .

Whilst more of both is always nice, I'm not chasing peak HP.... or max torque... or any big raw number.  I just want to acheive the best overall result for my particular setup. The gain will be most likey in the how it does what it does rather than doing any more of anything I suspect.

Option G

work with Rexxer to establish a local shop that can work with their HQ to develop the Australian market

Well for me that would be perfect and whilst for an existing Dynoshop the AU$7000+ initial investment isnt astronomical..... the market Down Here is but a small one.  So I cant see it happening anytime soon.  

Listing those options wasnt intended just to illustrate whats available to me, but hopefully to make clearer the possibilities for us all by.... making an example of myself  .

Just ordered my Protune Remap kit from Motowheels!  They just got them in stock for the 696's.  A little FYI if anyone has been looking for them.  Up until now I think the only way you could get one was to order it directly from Protune in italy.  I'll post more once I get it and install it.

Details on which stage reflash you went with?

Let us know how this goes. I have yet to pull the trigger on desmoworks/motowheels protune/ rexxer...

Just curious on why you went with the Protune unit vs Rexxer. It seems you pay a premium for the Protune that offers less features than the Rexxer.

I went with the stage 5, which is "race" slip-ons and filter.  From what they say it is equivalent to dp ecu but with smoother low rpm.  O2's are disconnected.  It will arrive on the 16th, so hopefully I'll have an update that night [moto].  Honestly, I went with the protune vice rexxer simply because I wasn't having any luck figuring out how to get one in the us and couldn't read German. I know desmoworks is offering to flash your current ecu with their rexxer, but I wanted the hardware myself.

Nein!!!!!!!!!

Ich auch nischts.  Schlaff zeit hier, Guten Nacht.

Did you get the stock file to load?

[Veloce-Fino]

Nein!!!!!!!!! 

You smashing your head into a brick wall is quite discouraging for someone else considering the same option..

You should write a guide/instructions once you figure it out. I'm sure it would help plenty of people (me).

Nein!!!!!!!!! 

I see the pic you posted. Do you have the Rexer User and can't get it to work ? I'm asking because I've been emailing Christain at Intermot and He's been very helpful reads and writes english very well. If you need his email address let me know. I'm about to pull the trigger on the Rexxer User unit but if you can't get it to work I'd like to know. Christain makes it sound very simple to use there unit and from his emails it seesm like you get the most bang for the buck with Rexxer Unit. I hope it's not to good to be true.
Thanks

Link, both DucNaked and myself have the Rexxer User unit.  At this stage.... there are problems.  We're already in contact with Christian who - as you say - is extremely helpfull and I have no doubt that he'll do whatever it takes to resolve the current issues.  BUT...  at this stage I would hold off buying the Rexxer until we have a resolution.  Feel free to mention  "ungeheuer in Australia" to Christian.... He's well aware of the issues we're experiencing and that we're awaiting ... satisfactory outcomes.....

On the surface it does seem like the Rexxer unit offers most features for the $$, yup.  Over and above just reflashing your ECU, Rexxer promises the following:
1) Automatic Stock ECU back-up.
2) Error code diagnostic/resetting function.
3) Service light reset function.
Whereas ProTune we know is just a reflash tool, with none of the additional functionality listed above.

But thus far we have learned that the Rexxer Unit will NOT - despite their earlier assertions - back up the ECU's original mapping before uploading the tuning map reflash.  

Exactly as was reported of the ProTune unit on TOB.  

Christian resolved this issue by sending me a copy of the stock ECU map to keep as backup.  But.... as I said above, currently there are issues preventing all this from working as it should.

Christian and Rexxer are preparing to exhibit at the Intermot show in Cologne early next month and so I'm sure they'll be keen to have all the current issues resolved prior to then.

You might like to let him know that you're eagerly awaiting the outcome before you buy  .  A little pre-sales pressure goes a long way  .

DN and myself will keep y'all posted.
