Ducatidiag, a must have for every HM owner! - Ducati.ms

Ever since I got my Hyper I noticed how the throttle had an on/off tendency. This made my bike very hard to ride compared to the silky smoothness of my 749's throttle. It was a bit weird since according to the previous owner my bike has a DP ecu(which after checking turns out to be true) and no more closed loop, so it should run fine? Well, it didn't.

To add to that I had the service wrench on my screen just because the service was carried out 50 miles before the wrench came on.

I called several dealers and they all asked between 40 and 100 euro's just to do that, they asked even more to adjust idle and fuel trim.

That's when I came across this:
Oh My!

For ~$20 I could do all that stuff myself, at just a fraction of the price. It was a bit of a hassle to get all the cables but it was all worth it. I started with resetting the TPS which was a bit out of calibration( was on 3,4 degrees and should be 3,2 +/- 0.1 degree). Then I went to a local workshop here who has a gas analyzer. I hooked it up and the fuel trim was way too lean. I was getting 1.20 lambda stock.

After a bit of fiddling I settled on a fuel trim of +7 which gave me a lambda of 0.93~0.95. Then adjusted the idle screws and the bike felt like a whole different bike. It has a bit more grunt now down low and has a pretty smooth throttle feel. Furthermore I reset the service wrench and read out the fault codes.

The gas analyzer measurement cost me 15 euro's, and the cables another 15 which is still at least 10 bucks cheaper than what the dealer would ask for a tps and service reset.

Just like VDST for a fraction of the price, and thanks to Gilly for pointing me to this

As as wrote on the other forum, great that it's working!
How is the fuel consumption now? Did it went up after setting the fuel trim to +7?

I have no idea, have yet to finish this tank of petrol. It has 115kms on it now and I usually go 120~130kms with a full tank until I hit the reserve.

Since you are only adjusting IDLE fuel trim, there should be no perceptible change in fuel consumption. Adjusting idle fuel trim adds or removes a small amount of fuel at idle (duh!) which does very little at higher RPM.

When I did the DucatiDiag Flash from stock map to the DP, I can just barely get 100 miles to a tank.

I should have taken some snap shots of the stock versus DP map, the low end fueling is the same, the mid range is perked up a little bit, top end looked untouched. This was using another piece of software that lets you load the stock or DP map and compare % of change between maps.

As you state, cleaning up the tuning on the stock setup shouldn't change much with overall fuel consumption, but it does make for a happier motor. What JP is doing is just too cool.

Yup, basically, with this and the different front fork springs the bike is how Ducati should've made it in the first place, it feels perfect now. Fuel economy hasn't changed a lot and when pressing hard I get a consumption of 1:12~1:13 (l/km), and highway somewhere between 1:15~1:18, which is pretty impressive for such a thirsty bike. My RSV 1000R Factory did anywhere between 1:5 to 1:8 when riding at the same pace, really ridiculous fuel consumption.

Nice find; going to read more up on this. Hopefully I will never need it though :P

Got a question for you guys using ducatidiag. If I have 2 ecu, and I want to swap between the 2 temporarily, do I need to register the software 2 times?

Drinky · Sep 7th, 2011, 5:38 pm

Yes, you need a license for both ECU's

It does not work for HM796!!

My cable arrived today. When I opened the seat trying to do the dump, I found the diagnose port is 4 pin. The 3 pin cable can't fit. What kind of cable it is? Can it be purchased somewhere cheap?

The port is shown in yellow in my attachment.
