ECU Reflash updateECU
Posted 17 March 2012 - 04:27 AM
I have been trying for sometime to solve the closed loops sensors without resorting to any of the resistor based solutions. I can report that these 2 reflashes work. I tried both today. My 02 sensors are unplugged (no errors) and my exhaust flap is now permamanetly fully open. The result - instantly much smoother below 3500 rpm.
You will be able to use a power commander across the entire range when it is commercially available.
You need to send Chris your or a spare ECU with the latest factory flash. You must organise the shipping both ways.
No changes to the fuel map, both flap and 02 turned off. Senors need to be unplugged.
We suspect that a Factory reflash will wipe it out?
Lower cost - but you need to send your ECU unless you live near Bristol UK.
Your ECU is backed up and reflashed while it is in the bike. The reflash is specific to the serial number of your ECU. Your ECU can be reflashed if there are Rexxer updates. Senors need to be unplugged.
Fuel re mapped to suit a slip on. Unlikely to need a PC V unless you are chasing map prefection.
More expensive and you need to find a Rexxer dealer close by.
I am running the Rexxer and will put it on a dyno at some stage.
No work around is perfect and this might not appeal to those that want to able to take a cheaper resister based solution on and off themselves. A reflash is the purest way for me. It is binary - the 02 and Flap are just turned off not "maniplulated".
Hope this helps.

I have also read that the guys with Multistradas are very happy with the Rexxer flash.
Have you done the filter with the slip-on can with the Rexxer?
My Austin racing can is open and she "snaps, crackles and pops" on decel running down hill after been hard on the throttle.
I was showing off at a mates place revving to show off the sound and she spit a couple of blue flames
Will the Rexxer help with this?

Thank you for putting all the hard yards in with the ECU reflashing and keeping all of us up to date with your findings.

In terms of the crack and pop - it may not, it will depend how close the profile of your slip on is to the QD system they based the map on. Rexxer is from the company that sells the QD slip on.
I have the CW with DB killer and it has never really popped so I can not give a before and after comparison.

The 02 sensor is only used at idle and low throttle openings to enable the bike to pass emission levels. As soon as you open the throttle by any degree a predefined map is used. The benefit in disabling is better running under part throttle.

But ideally the best plan would be keeping the sensors AND improving the rough running too? Sorry, I'm getting to be more of an environment Nazi in my old age. Especially when taking the easy way out hurts the environment. I am quite conflicted about replacing the huge factory monstrosity exhaust with cats with something else for cosmetic reasons. I have heard the excuse that "my other vehicles are green so I can justify removing all the emission controls on my bike", and I don't buy it. Damn I must be getting old. Of course I also think gas guzzling vehicles of all types are an anachronism. Seeing soccer moms driving around alone in 7,000 pound monster SUV's makes me a little ill.

Yeah, isn't that depressing

I understand about OEM - I'm even running with the ugly rear fender to stop the Gestapo harrassing me.
You are correct, any Ducati dealer can reset the ECU back to standard for any tests you may be forced to do, with a factory reflash. You can then reapply the Rexxer map at any Rexxer agent as long as you have the back up file which includes your ECU serial number. Both tasks are performed accessing the plug under the seat.
I also understand this is not for everyone, my feedback is aimed to those who are considering it as a solution rather than resister based options like FatDuc/Redline - Shift Tech/Powercommander manipulators.

I have read that it is like this for a Mulistrada, I know this is a very different bike to be ridden off rd sometimes

I don't know about gears, the ECU gets input from many sensors so it it may be true. I do know the ECU is exactly the same unit as the MTS, however importantly, the file structure on the map is very different. You can however swap them and reflash either unit to the others factory map.

I'm confused, I thought you were over the rexxer flash back in December and I'm so close to ordering the new PC5 available in Austrialia in a few weeks, so do I have to rethink?
Quoting Paulin Hanson, please explain the back-flip with rexxer reflash?
PM me if your uncomfortable posting a reply.

While that was getting done the Rexxer was sorted. So i had two. I staid with the Rexxer as it was the costliest and there will be ongoing support. I am loving how much smoother it is. A power commander will now be effective across the entire range, but I can wait until I have settled on a quiter exhaust than the CW.
So there is an ECU available as a swap with the latest Ducati flash with the 02 and Exhaust off available. As mentioned further up the post, any factory updates may wipe it out.

I'm running it in a higher gear, smooth low revs and pulls hard with no flat spots.
With my open pipe it is not as loud at cruising speeds due to running a higher gear lower revs.
The decel popping has stopped apart from when you are up it but no where near as loud and often as before.
My running temp has dropped too
