Siemens ECUs - the reflash/modding possibilities

[asherrick]

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

Doh!  Desmworks ECU flashing service is looking more appealing.  That is, unless I can convince myself that the Rexxer is worth the extra $230...

Agreed, I am thinking that US$300 is more appealing...

I bought the Rexxer and with shipping to US it was well under $600.00 US, I guess the dollar is taken a beating again. You will be more than happy with the reflash for 300 it's a great deal & the mapping is fantastic.

The main benefit from here on out to purchasing the Rexxer unit vs getting a reflash,  is that the ReXXer unit offers the ability to reset the service indicator, and pull error codes, both of which are very nice for the garage-mechanic, who does his own servicing, and doesn't feel like always being stared down by the dash wrench.  Whether this is worth the cash difference or not, is up to each individual it looks like

Well its certainly not susceptible to currency fluctuations thats for sure!   Other considerations are these: If you have only the one ECU then you're off the road whilst you send it away for reflashing. And If there was any error or bug in the reflash then you're off the road (a second time) whilst you return the ECU to have it rectified....  It does seem cost effective.... but I'm happier with the convenience of owning the device..... recent customer support failings notwithstanding.

Bringing back from the dead.

First a note. I am not posting this to slander Anthony or pro italia. Honestly, Anthony has been pretty good about responding to my questions and emails and such, so please just take this as me trying to understand what may have happened.

I am going to paste an email that I sent to Anthony the other day. I believe that the email was forwarded to Christian at rexxer for help. Any thoughts or ideas are appreciated. I have 2 ecu's one that came factory installed in the bike, and another that I got used that was tested as good that was reflashed by anthony.



Anthony,

I just did some more testing on the bike, and ultimately reinstalled the oem filter and my stock ecu. 

I first tried turning the key on and off several times, let the bike idle for a few minutes to warm up. During the warm up I tried using the fast idle, and the bike didn't seem to respond to it like normal, it sounds and acted very lean. I rode the bike around the block and it continued to surge. At part throttle the bike ran awful, it would fall flat on it's face and if I gave it a little more throttle it would surge. felt very dangerous because the bike would fall flat on it's face, mid lean this could be very bad. 

Next I swapped the MWR filter for the oem. Same results, although felt a little less lean. Still completely un rideable and the diffence really wasn't that great. 

Last I replaced the ecu with my oem, completely stock, factory ecu. The bike rides normally. I didn't even force the tps to reset when I put the factory ecu back. 

Since the bike runs completely fine with the factory ecu, without me even resetting the tps through the key on / off procedure this seems to indicate to me that something is wrong with the flash. 

Thoughts?

The ECU which you got used: Was it tested as good by you on your bike prior to the reflash?

[ChrisH]

Yup!

[DucNaked]

Have you heard back from Anthony or Christian?
I don't see why they wouldn't reflash the ECU. It wouldn't cost them anything and it takes less than a minute to do.
What type of map did you get and with what options?

[ChrisH]

I haven't heard back from Anthony today, but like I said he's been great so far so not too worried there.

The map was supposed to be for slip ons, MWR filter, removed o2 sensors, and stock rev limit.

[Veloce-Fino]

Just wanted to update everyone.

Anthony reflashed my ECU 2 weeks ago and sold me an MWR filter to go along with it.

He recommended a flash for me that removed 02 and raised the rpm limit while richening the a/f mix.

He did a PERFECT JOB with choosing the right tune. Bike is running like a dream. I pulled the plugs and they look really healthy. Not white anymore like before the tune.

I bought an ECU off ebay for a $50 a few weeks ago and he flashed that one.

I can't believe I ever waited to get this done, the bike is a completely different animal now.


Thanks Anthony!

Does anyone know if you can re-flash a 696 ECU to run a 1100?  Does the re-flash just change the fuel tables or is it an entire chip re-program.

The reason I ask is its easier to find used 696 ECUs.

Thanks,
Chris

Ask Anthony at Desmoworks.

[DucNaked]

Ask Anthony at Desmoworks.

And then post back with the answer, I would also like to know.

Yes. I have 696 flashed to 1100.  Works with no problems
