Ducati Monster 620 Wire Harness / Bike Running Problems

[Howie]

The condition of the dash should not matter if the immobilizer is turned off.

Ride with no dash and see if problems are still present.

The bike starts with no problems without the immobilizer. I'm gonna head out this afternoon with the dash in a backpack to see how it runs with and without it.

[thorn14]

It should do just about everything except record mileage, run the blinkers, and maybe one or two other tasks without the dash with immobilizer disabled. The last time I looked at the actual pin diagram was a few years ago though.

The bike ran really well with no dash. Good smooth throttle response and felt consistent throughout the RPM's. It hasn't felt like this in years. I rode 40 miles and stopped to put the dash back on. On the way back the throttle response was good, a little smoother at higher RPM's but rougher at lower RPM's. Which is what I've been experiencing for a long time but with much shittier overall throttle response with no oomph.

I took the gauges apart last night, didn't see any apparent damage due to previous meetings with the ground.

Background info: I had a crash 3-4 years ago going about 2 MPH. Was pulling to the side of the road and lost front wheel traction on something that came off the surrounding trees. After getting the bike back up I tried to start it but would only crank. It took a while but it finally started. This might be when this specific problem started.

I've looked at the wiring diagram and don't really have a answer as to why the bike runs differently with the dash on. It shouldn't.

I'll email SOS Diagnostics, maybe they have dealt with this before. Maybe I'll look into aftermarket gauges too.

Update: I bought an ecu on ebay from a s2r1K for $100, looks like it had been reflashed with a DP map. It had a sticker on it that wasn't OEM. Anyway, I read and saved that file on my pc just in case, you never know, and flashed in my DP 620 file. I checked the TPS, synced the TB, set the idle and set the CO at 4.5%. The bike runs great, no more shitty throttle response, really smooth again. It sounds a lot better too. It felt like I was dragging an anchor when on the throttle before.

I don't know what was wrong with it but my original ecu had problems.

Thanks again for the input guys.

Great outcome! ðŸ'ðŸ»

Good to here the ECU fixed your issue. So your late 620 had the 5am ECU? All info online says the 620 only had the 5.9 ECU. My 04 had a 5am with a different hardware number than the s2r bikes. I want to reflash mine but have been affraid due to reports of damaging the ECU if the different hardware numbers are used. What software did you use for your reflash? Where did you find a DP 620 file I keep turning up empty handed in my searches.

Interesting thread on GuzziDiag/TunerPro - http://www.ducatimonsterforum.org/index.php?topic=67714.0

LONG WINDED ANSWER BELOW  

Yup 5am HW610 on my bike. I've seen the 59M info too. I bought the bike with 2500 miles on it about 10 years ago, the previous owner had installed the Termignoni package (pipes, open airbox and ecu). I don't know what the orig ecu model was. I used the GuzziDiag writer to flash in the file with cables I bought on amazon.

Here is the GuzziDiag site:
http://www.von-der-salierburg.de/download/GuzziDiag/

You can use IAW Diag V0.47 to check parameters, do testing  and change the fuel trim like the VDSTS software. The reader I used is IAW5xReader V0.28 (5AM, 59M) and the writer is IAW5xWriter V0.24 (5AM, 59M).

Here are the cables I got:

Some people had problems with the 3 pin connector from Amazon - one guy fried his ecu, said the +/- wires were incorrectly labled. I checked mine with a multimeter. At the bottom of the GuzziDiag page it has a diagram of that connector. Thats what I used for testing

These guys guarantee their cables

Yes you need to be sure the file you are writing is correct for your ecu model and hardware number.

I was researching TunerPro, software that allows you to change anything (I was just looking to disable the immobilizer) in the ecu as long as you have the correct files to use it. FYI dangerous to change things if you don't know what you're changing. I only messed with the immobilizer.

I found out that it uses a BIN file(that's what's in our ecu's) and an XDF file (these are custom made) (that's the framework that the BIN file is attached to so we can view the information correctly) to work.

TunerPro http://www.tunerpro.net/

I found XDF filese here http://motoxdf.wikia.com/wiki/Motorcycle_Tuning_XDF_Wiki but they were in text file form and I couldn't figure out how to save them as an actual XDF file.

In looking for the XDF file I needed I came across someone on another forum. I texted him and we went with email from there. I got the XDF file I needed as well as a fresh DP 620 BIN file. I'll keep him anonymous cause I don't think he'd appreciate me giving out his info.

I disabled the immobilizer and wrote it into my ecu. It took about 15 mins. Make sure you have your screen saver turned off as I was told that if the writing is interrupted you could screw up your ecu.
