ECU reflash

[jrjoe57]

So in the end are you satisfied with the DesmoPorsche ECU reflash?  I am considering sending mine out or just getting the Fat Duc O2 emulator.  07 S2R Full Arrow no baffles.

Joe,

I got a reflash ECU from DesmoPorsche and installed it last week. Reset TPS and Trim, adjusted air bleeds a little and away I go! You do need to have a VDST or get a dealer to reset things.
I have no problems with recommending their service. I did all this and I live in Australia.

Thanks Vossy for the encouragement, how did you know what adjustments to make to the TPS, Trim and air bleeds? 

[vossy]

The TPS will reset itself with the help of the VDST. (easy)
The trim was done by ear and a couple of short test rides. The trim starts off at zero on the computer, so you really want it to be slightly richer for better idle. Then I adjusted it to the point where it started to idle rough and backed it off a little, checked idle speed, test rode and adjusted some more till it felt right.  The air bleeds were done using the VDST to firstly get the bike idling at the correct speed, rechecked and tweeked the trim and test rode again.
All up I went for 3 short test rides with slight adjustments inbetween and it runs great.
A mate who is a car mechanic helped me with the trimming by ear because that's what he does best.
hope this gives you some insight to what's involved.

there's lots of great info on here that can/will run you through the process better than I can explain.

+1.  The first time I tuned the bike I used a Gunson Colortune.  It's a spark plug with a glass window in the top so you can see the color of the flame.  Way cool toy and much cheaper than a gas analyzer.  Since then I've gone to tuning by ear as above: richen up slowly until it stumbles and then back off a bit, then a test ride to make sure.  As said, once you connect to the ECU it's all fairly easy.

made the changes to the keyspan usb adapter as suggested from the faq page on the technoresearch site, and the vdst is now communicating decently with the ecu.  just to clarify though, the trimmer value is saved when you have the screen below, right (and therefore you know that the chip was truly flashed to DP spec)?  also what trimmer value are you guys using?



now to troubleshoot why the gauges are displaying max air temp and max speed:

[dbran1949]

I have no direct experience with VDST but typically when a sensor reads maximum values it means it is not connected i.e. the input to the measurement device is floating

[scott_araujo]

Yes, trimmer value is saved.  If you're unsure go to another screen and come back, it will reload.

I'm about 13 I think BUT don't worry about that too much.  Get the bike running right and don't use someone else's setting EXCEPT that if you're way off something might be wrong.

just to verify everything worked properly with the software and cable etc, i hooked it up to a friend's 848 (with a genuine DP ecu)... gauges worked properly, including speedo and air temp (his read 80 something).  also, i took a look at his trimmer setting, and it was set to 35... but his bike had been properly tuned at AMS.  do dealers have access to the full fuel mapping across all throttle settings?  i put mine to 30 (it was indeed saving the 15 value from earlier) for a quick ride home and my gf followed behind me and said it shot flames a couple times on decel.  so...maybe i need to back that off a bit.

I don't have an S4R but I do have a DP ECU and the trimmer value according to VDST is set at 15 currently. I have no running issues. I think +30 may might be way too much.

yeah, definitely.  the friend i borrowed the vdst from has a 1098 and says that he likes his at 15.  so i may try 15 for a bit and see how that goes.

[vossy]

I've just set mine up last week and it's trimming is set at +20. Runs beautifully.

I'm glad you've had some headway with your set up McKraut.

[♣ McKraut ♣]

well...i think so.  though in a thread i have in tech (http://ducatimonsterforum.org/index.php?topic=39013.45) i'm being told i may need to actually be using TPS adjustment screws to actually reset the TPS, not just a software thing with the VDST....  so i guess after work tonight i'll have to get out a flashlight and go hunting for those screws...  just when you think you're making headway with something...

also i need to figure out why the air temp sensor (and speedo) aren't registering on the vdst.  fun times.

Any new info out there?

Im about to start an ECU adventure of my own. Im shopping around for a full system, i plan on getting the TPO Beast-R intake kit also. I will definitely need my ecu flashed. I sent emails to desmoporsche and motowheels inquiring about a map for this setup. After the flash is done it looks like all i need is VDST to finalize things. Easier said than done. Has anyone accomplished this successfully? Vossy, your story is the light at the end of the tunnel. I think you have the same bike as me too.

Im in the Los Angeles area if anyone has VDST and is willing to let me use it.

Bike is '07 S2R1k

Hope we get this mess sorted out. Every shop i call locally uses a different method for exhaust mods on my bike, Eh...

[vossy]

I'm sure things will be fine with your ECU re-flash.
If you can't borrow a VDST (must be the one for your 5AM ECU), you really have only two options.
1. buy your own VDST, well worth it if you plan on keeping the bike for a while.

2. take it to a dealer who can set it up for you.


I'd be keen to hear how you go with it all.


good luck!
