ECU reflash

[silversled]

McKraut,

The cable is coded for the ECU type.  The screen showing the "Product Name" as MM-IAW5AM is reading the cable not the ECU it is connected to.  

I've PM'd you.

Vic,

battery voltage can be an issue too.  i hook up a good charger if i'm having hassles getting mine (pro version) to connect

[silversled]

If anyone can get a "Standard" 59M cable to work on a 5AM ECU or vice versa, please let me know!

Inquiring minds.....

tried doing some work with the VDST (5AM) again on saturday (i just want the TPS reset and fatten the fuel trim), and this time also tried doing the suggestion of someone in another thread of actually firing up the engine, and then killing it with the red toggle but leaving the ignition on (to prevent the ECU entering it's sleep mode).  that, too, didn't seem to help.  i was able to, only once, get the TPS portion to go through the countdown and then eventually say "PASS".  so, i'm *hoping* that at the very least, the TPS is reset for sure.  the fuel trim (and just about everything else), however, was greyed-out...not accessible.  at one point, the VDST even was telling me i had a 15M ECU (which i think is for the older 900's and 750's?)... then i hit the motorcycle icon again and it was back to 5AM.  though, as far as i know, i have a 59AM.

so, at this point it sounds like i need to make a couple of phone calls.  one to desmo-porche and make sure i do in fact have a 59M ecu (and it was in fact reflashed?  is there some way i can verify that short of buying my own 59M VDST?).  and two, to technoresearch makers of the VDST, and see if it's just not possible to use a 5AM VDST on a 59M ecu.  of course it's also possible i'm a giant idiot and just can't figure out how to use a vdst properly, and am just doing it all wrong somehow.

oh, and then i forgot the second part of this.... on my way home on sunday night, it kept dying on me when accelerating from a stoplight.  during a 10-15 minute ride home, it died five or six times.  it was right at about 3k rpms in first gear...i could hear this "cough" down from the intake area, and just like that it was dead.  now, i had the same "cough" at the same rpm spot with a completely stock ecu, which i noticed with gentle acceleration from a stop, or for instance when making a right or left turn from a stop light... i would get this cough right at 3k and then a tiny loss of power, but then it would pick back up again.  it always bugged me, because it's never fun to have something screwing with you when you're trying to make a nice smooth corner.

anyway, the only thing i've done in the last few days that would have any influence (besides the DP ecu flash and subsequent attempt to reset the TPS with the vdst) is a chopped airbox and a KN performance filter.  is that normal?  have other people out there run into this same thing before?  i wouldn't think simply opening the airbox would be THAT drastic such that it kills/stalls the engine.  and, like i said, i did notice this "cough" before with the stock ecu... now it's just bad enough that it's killing the engine when it happens.  thoughts?

in re: 5AM working on the 59M ecu, i just talked to a nice guy at technoresearch and he said TPS and fuel trim adjustment have the same address and i should be good to go

still having issues with the bike.  i've been able to get the following message with the vdst:



but after talking to bobby, he said that it is possible to get that message and not have actually reset the TPS.  he also confirmed i have a 5AM ecu, which is the cable i'm using...so all should be good, but communication is spotty (at best) between the ecu and the software, and i still haven't seen the stuff like gauges and temps display, nor have i been able to get the fuel trim slider to show as available.  bobby did offer to flash the ecu again to make sure it was done or done correctly.  i may take him up on that...  is it possible the flash wasn't done right (or maybe not at all)?

i just want more fuel!!  it shouldn't have to be this hard...

it shouldn't have to be this hard...   

Good luck and thanks for keeping us posted.

I just hooked up the VDST to the reflashed S2R1000 tonight and had similar issues to McKraut.  I noticed that the USB adapter's driver defaulted to COM3 which was already assigned to another resource on my laptop.  I forced the USB adapter to use COM2 and the VDST software synced up and behaved properly afterwards.  After this, all the features worked except the immobilizer function which was disabled in the reflash.   After bumping up the fuel trim, the bike fires right up now.

Off to do a full tune tomorrow morning.

Your all so lucky us 696/1100 guys have to fork over $1200 for a DP ecu ($1300 w/ termi's) or buy the PC V for $310 for basic tuning not even gaining the max RPM boost..

DAMN my Siemens ECU!!!

I don't want to scare you, but there is a possibility the ECU is not communicating since that would explain no sensor readings.  A trip to a shop with a DDS tester (factory scan tool) will clear that up.  They shouldn't charge too much to just hook it up and see if it communicates.

From everything I've read the USB adapter is finicky. I use the old serial port and have never had an issue connecting. I know serial ports are uncommon these days but that would remove one variable from this equation.

McKraut,

Swapped out my ECU for a Desmo DP ECU just the other week for my 08 S2R1K.  Bike ran very rough without the TPS reset.  She would have difficulty turning over and occasionally would stall.  I had some trouble with getting the TPS reset but once I got it, everything was good.  She is now running great!

When you hook up the VDST, you should be able to go to the gauges screen and see your Engine Temp, RPM, Speed and TPS.  Start your bike to ensure you have a good connection.  If you do, the gauges with be moving.  What's your TPS Reading?  Is it moving a you move the throttle?  Should be around 2.8 closed and 85 full open.  Regardless, go back to the TPS screen and re-try the reset process.  The VDST will tell you to shut off your bike if its still running when you hit the reset button.  

Now, check how she idles and look at the TPS reading from the gauge screen.  Should be between 2.8 and 85 as noted above.  You can check full throttle with the bike off.  Finally, go to the screwdriver icon and select idle fuel trim adjust as may be needed.

Hope this helps and PM me if you have questions.

I finally put my reflashed ECU in my 07 S2R1K and hooked up my VDST. After the initial TPS reset and trim, I adjusted the air bleeds slightly, rechecked everything twice, and now it runs beautifully. I only had time to take it for a small test ride with now problems with the running.
 one thing to make absolutely sure is that you have a good battery and good connections to it and serial port.
The communication between the ECU and laptop can also take several seconds or so. You also may have to close out of the program and reopen it for better communication. I had to do this while doing mine.
I had my throttle bodies sync by a mate of mine with a manometer before I stared.
My TPS is 3.2 and the trim is set at +20, and the air bleeds turned out about 1 full turn from fully in.

cold start up no worries [moto]

+1.  Mine takes a while to connect and can lose the connection sometimes.  Changing to a different com port may help.  I would agree though that if you're not getting gauges it's probably not connecting properly.
