Multi vehicle diagnostics

[liftemhi]

can the predator u7180 be used on other vehicles for diagnostics . i own 2 a 2004 and a 2003 and would just like the see the diagnostic on each of them

[mikel]

Yes...

[JonDiablosport]

if it the same type of vehicle there is a possibility you will be able to. the tool does not have to be married to a specific car to do diagnostics.

[liftemhi]

now thats the best news i've had all day Thanks
one quick one can you just use it as diagnostic tool or does it have to married before it can be used. can i just plug it in and run diagnostic . i have not hooked it up yet. so in the following the instructions
1.plug in the predator
2.the first screen you will see is the start up screen with the name of the vehicle the predator supports
3.performance tune should be three choices Performance Tune____Diagnostics_______ Options

so i can just click on the Diagnostics and run it , also will i be able to download and print off on my pc the Diagnostics report like balance rates etc

thanks i love the quick replie

[mikel]

you can use it for diagnostics on any 01-05 duramax and most similar year gas vehicles, married or not

No printing off reports, you can view the data in real time, or upload it to a PC, or live stream it to a PC in the truck.

ok but once i upload it to a pc ,i should be able to print it then yes, so i can hook up a laptop to the programer in the truck and view live stream wow idid nott no that ....this thing just keeps getting better

thanks again your kinda making my day

before i pee in your cheerios...this is a newer tool, correct? Purchased new in the last 2 years or so, revision 9rXX on the main menu?

[liftemhi]

wow ,i just ordered it last week from xtremediesel (XDP diesel) and got it yesterday,as for the revision 9rXX on the main menu? i guess i'll have to turn it on hehehe
can i read info then bring it in the house hook it up to pc a upload info or does the pc have to be hooked up at time of reading info

thanks again
this may be just me but i like milk in my cheerio's

[mikel]

just powered up is fine, but if you just got it from xdp, I'd guarantee its a new tool

ok the people are telling me that the preadtor will not give me accurate balance rates or the correct cylinder of the rate as some readouts go by firing order instead of cylinder #.
here are my rates
1 -6.992 -6.992 -6.992 mm3/s
2 -6.992 -6.992 -6.992
3 -6.992 -6.992 -6.992
4 -6.024 -6.586 -6.024
5 -6.164 -6.680 -6.992
6 -6.992 -6.992 -6.992
7 15.01 15.01 15.01
8 1.117 0.8672 1.117
desired rail presure 4300.8 psi
injection timing 5.002 degrees

THANKS FOR ALL THE HELP
sorry to keep asking

[mikel]

those are pretty high numbers, on our 06 LLY I see balance rates of -2 to +2%.

Was this fully warmed up?

To be honest though, I am no diesel diagnostic expert, let me see if I can find out what this is telling us

[liftemhi]

ok thank you for all the help.could you let me know about the balance rates are by firing order or cylinder #. wow -2 to +2% no see that. but it was not fully warmed up cause its smoking a lot and injectors are making lots of noise. test was done in park and i didn't know if i should take a chance and warm it up then test . but i could do it

thanks again

The balance rate adjustments are utilized by the ECM only at idle. The balance rates are the fuel adjustments for each individual cylinder based on the variations in engine crankshaft speed. A positive value indicates that fuel is being added to each cylinder event, such as with poor engine compression or a fuel injector that is not flowing enough fuel. A negative value indicates fuel being removed from each cylinder event, such as a fuel injector that is flowing too much fuel. The balance rates will change depending on if the transmission is in Neutral or Drive.

The Test procedures in steps:
1. Start and run the engine until the engine coolant temperature (ECT) is more than 82°C (180°F).
2. Turn OFF all accessories.
3. Hold the brake pedal in the fully applied position. A hiss will be noticeable when the brake is fully applied.
4. Place the transmission in Drive.
5. Idle the engine for more than 30 seconds.
6. Record the Balancing Rate Cyl.1–8 parameters from the predator or trinity tool while the engine is at idle speed.
7. Repeat steps 2–6 with the transmission in Neutral.

Are all of the Balancing Rate parameters within the first specified range in Drive, and the second specified range in Neutral?

Drive: −6 mm³ and +6 mm³

Neutral: −4 mm³ and +4 mm³

Hope this helps out a little and gives a better understanding.

Thanks Buck!!
