Siemens ECUs - the reflash/modding possibilities

[Link]

So which is better....

Rexxer or Protune?

Or the same.... ?

Not sure but i think as far as how your bike will run there prob. real real close but IMO you get a few more features with the Rexxer one being able to get maps emailed to you and then you download them to the unit & install on your bike which opens up some options that are not avaible with protune refalsh. Two is the unit will read error codes. protune is total plug & play right now and Rexxer still has a few bugs. I weighed cost & features & went Rexxer from what I've read on protune you couldn't go wrong with either.

Jesus you're a pain in the ass 
So, on my nice relaxing Sunday I went out and braved the rain, wind, and cold. I unhooked those make the beast with two backsing sensors and went for a test drive!!!!!   
And the verdict is  Same errors!!

As you said they quickly go away and only occur when you snap the throttle closed. I don't know what to make of it.

Thanks for taking the trouble - in the cold and wet an' all - to verify that this issue is not limited to just me.  Next time you're in Australia I owe you  .

Hopefuly Christian can shed some light on the subject.

Soon would be good.....

I have an unresolved issue with my Rexxer reflash.  

My Rexxer reflash deleted the stock closed loop and therefor (in theory) the need for the stock o2 sensors..... but....

Since physically disconnecting and removing my stock o2 sensors I now get the "check engine" light illuminating when I roll off the throttle from above 6000rpm back down into the supposedly deleted closed loop area at 4250>>4000rpm.  Light stays on for around 4 seconds and then goes away.... until the next time I roll right off the gas.  Interestingly this only happens when actually riding, when in gear and on the move.  If I pull the clutch, rev the motor... or in neutral... no light.  I used the Rexxer to retrieve the DTC error codes (so I can confirm that feature functions well).  Both codes - P0133 and P0153 - are defined as "o2 sensor circuit slow response".  And yet the ECU is meant to be flashed to pay no regard to any o2 inputs.....   .

I emailed Christian @ Rexxer on Monday morning..... and am still waiting to hear if theres a fix  .

Yeah I'm counting.  Two weeks now and still no word from Rexxer.  They're busy - I know - busy doing stuff other than resolving my issue. I can wait, but  I just thought I should let you all know that if you have a Rexxer "issue".... dont hold your breath while you wait for resolution to become a priority.

I'll try to make it up to Intermot and talk to the guy.

If you make it up to Köln, make sure when you're at  the Rexxer stand to ask in a very loud voice "So...... when your reflash deletes the closed loop... does it completely delete ALL o2 inputs?"  

So which is better.... Rexxer or Protune?

Need to hear from a Protune user:  Does Protune really delete the o2 inputs, or like Rexxer is it just faking it?

ok for sure heading to Koln today. Will try to track Cristian down.

I need to speak to him as well. Just done the reflash, the new start-up message is in (although spelt wrongly!), and disconnecting the flapper valve motor doesn't show an error code, however my rev limit is still 8250, it should have been changed to 9500..

I posted on the other thread.

EPROM tables and EPROM chips, such as the FIM aren't useful on anything made after the 998.  Map ECU's took over.  Your information is great, but the solution isn't viable anymore.

You know... I'm just a little disappointed that the back-up response has gone cold at the moment.  I still run with a bug which needs to be ironed out and it would be nice to at least hear that Rexxer are working on it.

Many thanks to Raux for personally bringing the issue to the attention of Marco Daniele at Rexxer's Intermot stand in Cologne  .  I feel confident that now we have the Man Himself involved the issues will become a greater priority and we can once again give the Rexxer product and their customer support the  .

Cheers Raux - good work mate  .

Glad all this was brought out BEFORE I ordered one; so now it's

Agreed, let those with the disposable funds blaze the trail.

And Ung's an aussi so he's probably good with a machete.   Wild kangaroos and all...

When I get my map corrected & reflash, is there an easy way of telling if the closed loop section has been deleted?

Unplug the 02 Sensors.  If there's no errors it should be deleted.

Did Rexxer raise the price?  I'm seeing it for 449 EU ($675 USD)!

[ungeheuer]

Nope - same price.  But the US$ has deteriorated in value significantly recently.

I know the US$ exchange rate is bad at the moment (from a US buyer's point of view) but I'm calculating 449 Euro at around US$630.  That price includes German sales taxes which if you're outside of Europe you dont pay - so price without tax is around 380 Euro.... or around US$530 at current exchange rates.
