Siemens ECUs - the reflash/modding possibilities

[oldndumb]

Apologies for staying off track, but the mention of TuneBoy  brought up bad memories. I bought his product for a Triumph a few years ago and would not buy another from him. Without going through a long discourse, I had every sort of problem imaginable with it. I accept that these types of programs are finicky and extraneous variables can effect them. What I could not accept was the poor customer service. Don't believe me? Just go to a Triumph forum and read the comments. Initially, most cut him a lot of slack, but the complaints were cumulative and informational. Lucky for the Triumph crowd, a freeware program (TuneEcu) is now available for them that is superior in all aspects compared to TuneBoy. And, funny thing about the freeware, the developer actually provides ongoing support.

On a positive note, I sent a spare ecu for my 2012 1100 EVO to MotoWheels for a reflash.  I was pleased with the improvements. Certainly not comparable to a dyno tune, but fine for me as I am merely a street rider. I also now have a tiny bit more of underseat space, having been able to remove the exhaust valve servo.

Dissecting a monster this far is quite a task IMO

So, I just posted another question about this, but I should have read all the way through this thread first.  I want to get my ECU reflashed after installing my K&N air filter.  I read the post about Redline in VA that has a Rexxer facility.  My parents live somewhat close to that shop, so I could ride down there and get my bike tuned.  When I called, they said they could tune the bike and reflash the ECU for $400 vs. $300 to just send it in for flashing.  They also said it should make a night and day difference to bring it in because they will be able to tune everything the best.

So, I'm wondering, do you guys think it is worth me taking the trip down there in person vs sending my ECU in?  It seems like everyone else has been fine without the in person tune.

If they are talking dyno tune, it would be a bargain.

$400 for custom dynoed reflash?  Yup, I completely agree with oldndumb.

If you take it to Redline, they'll dyno it

Luckily my parents live an hour away from there.  I can either hang out for a few hours or just convince them to pick me up.  So, I'm thinking I will just do this instead of mailing it in.  I'm excited to see the results!

You have no idea how lucky your are that you live that close to RedLine.  As far as I know they are the only dyno tuning Rexxer reflash facility in the USA. The rest of us have to settle with canned Rexxer tunes unless we want to go the whole PCV route. Do it!

[696DCRider]

I thought getting the ECU reflashed would eliminate the need for a PCV.  If you still would need a PCV to get everything right, then it definitely makes sense to go to the facility and do it in person.  I'm going to have to take off early on a Friday and ride down there.  I will update the thread with my results afterwards.

Having your ECU reflash properly custom tuned will eliminate the need for a PCV.  Most of us just dont have that option  - in reality adding a PCV is hardly mandatory if the "off the peg" map is a reasonable "fit" - but better is... better  .

Can anyone confirm if the Monster DP Race ECU (the one included with the Termignoni exhaust) has disabled closed loop operation?

I read the Superbikes (848/1198) with the DP Race ECU have the O2 sensors disabled already, and I figure it should be the same with the Monsters, specifically my 696.

[Raux]

still closed loop

That pretty much summed up what I found and was trying to convey before the other thread was locked. I'm still waiting for my Power Commander kit to arrive, the vendor supposedly is waiting for it to ship from a warehouse.

Reflashing the ECU to eliminate closed loop and then just loading a fixed fuel map (either from Autotune or a dynotune) is certainly one way, but I was wondering how the ECU would adjust for changes in fuel/temperature/pressure without closed loop operation. I could see it using the temperature sensors, a MAP sensor, engine vacuum, and throttle position along with the fuel map to project the correct commanded AFR but it probably won't be as good as a feedback O2 system?

Also that's roughly $900-$1200 right there ($330 PCV, $300 Autotune, $300+ reflash). Protune quoted me $500 USD, MWheels/Rexxer wanted $600 USD for their reflashing units, but some vendors will reflash for $300. Then add in the cost of a dynotune if necessary.

the Rexxer maps are the closest thing to having your bike 'dyno tuned' without it being on a dyno, you can ask them to 'delete' the O2 sensors, but, the mapping if not mistaken[ung correct me], does compensate when the O2 sensors are not "deleted" . . .still at $600.00 for the Rexxer, it the best bang for the buck you can get and you get a nice tool to reset your service wrench

the maps when dyno tuned, the closed loop oporation part of the map, is made in such a way that while creating teh map teh close loop is disabled, this will make teh ECU compensate for the 'higher' VE values . . .
