ECU reflash

[jwoconnor]

 Two feet of snow in front of my overhead shop door means the bike won't see the road for a while. Once I reset the TPS and tweaked the trim it seemed to start and run fine. I won't know for sure until I can get it out for a spin. If nothing else I'll pick up another air-box lid and try both intake solutions. I'm happy with it.
This has got to be the most snow I've seen in years. Figures.

Since you seem to have some time, build a homemade manometer and balance the throttle bodies.  It's easy the last part of the holy trinity with CO trim and TPS reset.  It does great things for a smooth running at idle and low speeds.

Well I was able to finally get it out today. A balmy 32 degrees and the main road was fairly dry. During start-up I had to open the throttle just a touch to get it to fire but that could just be the cold. Kept the revs up near 2000 for a minute then it seemed to idle well. I let it warm until a temp registered then headed out. Went through the gear nicely, no hitch, stutter is gone. The Arrow pipes sound amazing! I got it back in the garage before frostbite set in so I'll revisit this thread when the temp hits 40.

Thanks for the update!  Sounds like you are pretty happy with it.

Had it out today for a bit longer ride, I think I have frostbite  [moto]
It runs up through the revs smooooth as butter. Cold starting at 31 degrees could be a bit better maybe.

Sounds good!
I want the warm weather to come back also...it's so close.

I too had an ECU re-flashed w/Desmo-Porsche but hadn't posted up yet because there was a problem with the first ECU that was re-flashed.

The problem was something hardware related in THAT PARTICULAR ECU.  So, I got a 2nd ecu and sent it back to Bobby @ Desmo-Porsche.  He re-flashed the first one again (it didn't help as that thing's FUBAR), and did the 2nd one at NO CHARGE to me.

I got the 2nd one back, installed it (being careful to do this with the battery disconnected), reset the TPS and I had the same issue as the OP did.  You have to open the throttle while cranking to get it to light-up.  But, after that...

It was flaw-less.  Idled smooth.  Made GREAT power.  No ecu warning flashes.  No funky stuttering while running.  Pulled HARD to redline. Never stalled.  Immobilizer shut-off (per customer request).  

BTW, for reference, the bike info:

2006 Sport 1000
Opened up air-box top (courtesy of a Dremel-tool)
Full racing (105db) Zard system
DP racing cams

In conclusion:  I don't know what's up with the open throttle to get it to start up, but if you can live with that (minor inconvenience IMO) it was bang-on!  I would recommend Bobby @ Desmo-Porsche.

Does the sport 1000 have a fast idle lever?  Are you using that when you start up or just leaving it and blipping the throttle a little on startup?
Sounds overall like great results, though.

No fast idle lever on this bike as it's got the idle stepper motor.  To get it to fire, I would thumb the button and then roll the throttle on a bit while cranking and it would light right off.

sounds like it could be the problem. like the computer is waiting for the fast idle lever to be set instead of messing with the idle motor???

[yotogi]

I wonder if his source for flashing the 1000DS motors is missing whatever is needed to control the stepper. Hrm...

Maybe, but after you get the engine running it idles just fine so if it were waiting for equipment it didn't have, then it likely wouldn't know to actuate the idle motor.  I guess...

Stew - Good to hear your report is similar to mine. It runs so much better than stock that I have no problem goosing it a bit at start-up.
Anyone with a DS1000 and the true DP ECU that could chime in on this?

[He Man]

any issues on extremely cold weather starts? like 10-20 degrees?

sorry for the off topic comment, but why do people want to disable the immobilizer?
