anyone have a scan tool?

[MrDude_1]

anyone here have a scan tool that can read my 04 749??

i just need to be able to see the TPS.... i plan to buy the cable/software for it (its only $195) but i dont have it yet and id rather goto the track this feb then spend the money on the scan tool.

anyone have one i can borrow/use? i just want to see if the TPS is set properly or if its another issue.

The way I see it once you get tot he track you won tneed a scan tool ever again for your bike. Since it will be scrap metal after you dump it a few times :lol: :lol: :lol: :lol:




im just pickin Travis dont get your feelings hurt honey :lmao:

Why do you need a scan tool for this? Every vehicle or motorcycle that I have ever had my hands on that used a TPS was able to be checked directly via a cheap $10 Voltmeter from ratshack.

because ducati was gay about it on the xx9 and up bikes...
its a setup similar to your vette and most modern cars..

on motors like you're thinking, you have a set TPS voltage as 0% throttle, and physically move the TPS to match that.

on this setup, the TPS is not movable.. you connect to the ECU with a scan tool and 'reset' the current state as 0%... then 100% is calculated from there as the highest value it sees.


the diff between your vette, my old LS1, and the newer ducs is, with the vette, it does it everytime because of the electric throttlebody.. with the ls1, it did it whenever the PCM reset (say, removing the battery)... with the duc, you need a stupid tool to reset it.



most SCANNERS wont have that ability.. but they will show me a standard throttle percentage. i can then use the scanner to see if it reads 0% when closed, 50, and 100.. ect..... i wont be able to reset it, but i can eliminate it as the issue, or see it 'jump' values from it being dirty/bad....etc..


basically i just need it as a diagnostic tool to view what the ECU perceives is the value.. not actually what the TPS sensor itself is doing.

You don't even want to know what it takes to get the tool from Ducati. And I believe it's the only one that will work. Cost is over 10k I think. Can't remember. Mac?

[SUM650]

Problems already, didn't you just get this bike? How many miles are on the bike? Is this normal for a Ducati?

[MrDude_1]

yes.

How many miles are on the bike?
6,1xx when i bought it... 7,3xx now..


Is this normal for a Ducati?

yes.



although you're not supposed to ride them.. you're supposed to look at how pretty they are (or arnt) most of the time... and only ride them once a month..... to the dealership.... for more work.... :lol:




anyway, i think im going to have to buy a scan tool... im probably going to get this:
http://www.technoresearch.com/Products/VDSTS-Motorbike/VDSTS-Motorbike
its $195... but it has many of the functions of the mathesis tool.

[MrDude_1]

fixed it... rode it ~50 miles today...... parked it tonight and mileage read 7,666.... :lol: good sign or what?

[mandingo]

I dont have the tool yet... I just went over the whole bike systmaticly until i figured out the problem...

Problem was that the charcoal canister broke internally. this caused two problems. first it was blocking airflow into the tank, dropping fuel pressure... and second, it let the carbon into the tank where it clogged the fuel filter...

i replaced the fuel filter again ($4 for filter, $0.33 for pump to tank O-ring) , and ditched the canister (free).. the bike already has the correct hose lengths and hose holders for standard tank venting, so i just rerouted it to be like that.

im still paranoid about the damn EFI on this bike though.. im used to having total control over the ECU.. even with the tool, i'll still need a powercommander for real fueling control... and it still wont have spark control... almost makes me want to build a mini-megasquirt for it.... only thing stopping me is the damn CAN commucations for the gauges.

sorry i'm late...

travis- its a REALLY good thing you didn't try to adjust the the throttle plate by getting a scanner to read the tps. if you did that, you would have had a whole other mess of problems. you can't (or shouldn't) adjust the throttle plate on the front cylinder (where the tps is located) without loosening the input rod to the rear throttle body because you'll get an erroneous reading. once you adjust the tps, the only way to adjust the rear throttle body butterfly valve is by hooking up an exhaust sniffer and using the ducati DDS (the 10k tool kenny mentioned that is only available to the dealer) to balance out co's, hc's, vacuum, and the fuel mixture. sure some one might say you could just hook up some guages to the ported vacuum on both cylinders and adjust the rear plate until it pulls the same vacuum, but i guarantee it will never idle correctly and you'll be down on power.

also, about the fuel control...that bike has the ducati 5.9 fuel injection system, so you DO have control over the fuel system, but be careful--the adjustment is right on the ECU, so if you short it out (which i've seen happen), you have to buy a new ecu, guage cluster, and lock set (along with a new red key) which costs around $3000. it kinda sucks, but thats how ducati tries to corner the market...

ANNNNDDD there you go. :wave:

i know this part... LOL
theres some ways around it, but none are as easy or as good as the dealer setup.

i NEVER said i was going to adjust the TPS. like i said in the first post, i just need to be able to see the TPS as the ECU does. a simple scanner could do that.
aka i couldnt FIX the problem, but id be able to see if there was one.

but i appreciate the honest help... if i try to do something stupid feel free to tell me before i do it.. lol

yea, that little adjustment pot.. i know about it, but i wasnt reffering to that.. its more of a overall fuel trim.
im used to working with a real 3d fueling map with about 24 offset and adjustment tables.. etc... total fuel control.. not just trimming it a little more one way or the other.
i wish someone would jump on the ducati ECU market like they do on the GM/Ford/etc markets...
imagine a $500 cable + software combo that let you do more with a laptop then that 10K Ducati tool can do....

So let me see if I am picking up what you are putting down. What you are saying is spend the couple hundred bucks and have the problem fixed correctly by trained ducati people who have the right tools? The Duc engineering staff didn't have service in mind for the do it yourself weekend mechanic?

one of the strangest things ive seen about ducati isnt their bikes.. its the fact that they have what amounts to a racing machine.. and they want to promote others to race it... however they do not release all the tools to do so away from the dealers.

name another make, bike, car or otherwise, that is often raced, but the vehicle has to go into a dealership for service?
if you come up with a name, its probably Italian.. lol


atleast its not all bad.. their warrenty system is pretty good... perfect example.. while looking over this bike, i saw the belt was wearing strange... probably a defective belt.

they're brand new belts champion put on for the previous owner... well, they're going to cover a free replacement. there wasnt much question about it.

normally i wouldnt take it anywhere.. but hey, its free. lol.

have you had he valve clearances checked?? the valvetrain on a duc is different than any other bike, and if they are out of tolerance (on the loose sde) you can take out the head in less than 1000 miles (about a $1500-$2000 reapir--and thats just the parts!!). you can learn how to CHECK them, but you won't be able to adjust them. i thought i'd mention it to you since your bike is just past 6K miles, which is the service interval.

yea, it supposedly had its 6k done.. but after seeing some other things on the bike, i went to the dealership today and pulled the service record.
they didnt check it, as the kid said he could... so im probably going to do it tomorrow (saturday)

and why do you say i cant adjust it? all i need to do is measure the clearances accurately, then call up one of several places that will sell shims on trade for mine... im not going to buy a whole shim set, but i can get the shims... i dont have a 749R, so i dont have to pull the head to do the closers...

[the_MAC]

measuring/replacing shims on that bike is more than just measuring the clearance and then putting a different shim in, but good luck...and make sure you put a rag or something in the oil drain holes in the head. do you have the valve clearances already??

Mac needs a scan tool to go to the bathroom.
