tire size is a problem

[speedy912]

Lets get the worst out of way first. I'm new to this. A new know nothing. I'm new to trying to program this thing. What I'm dealing with 5.7 block. Diamond pistons. Forged crank Stage 3 comp cam. 6.1 heads. 6.1 intake. TTI headers. 4.56 gear ratio. RFE45 truck 5 speed transmission. 2004 truck controller. Hotwire harness. All this in 67 Dodge Dart. Mix & match special. Engine tune is great. Having problems changing transmission settings. Can't get past tire size problem in predator. Is this a matter that I must see dealer for?

[mikel]

What exactly is the tire size problem?

Are you using a U7137?

[speedy912]

Using U9000. New user for about a week. Tire size is a problem for changing anything to do with the transmission. Predator tells me no tire size information and I cannot get past it. Do I have to take to a Chrysler dealer to get tire size in controller? Is there a way to get past the stopping point so that I can install my tire size? I'm not real happy Predator is not fully compatible with custom installations. Thanks, speedy912

[mikel]

Im wondering if maybe there is a module missing in your set up that is required to do the tire size change?

Ny chance you have contacted Hot Wire about this, as they seem to have good knowledge of how these swaps work.

mikel, guess I really need help. Today, Saturday August 29 took car to local dealer and whose mechanic is always willing to help with problems associated with this conversion. He tried to install a tire size. Did not work. He suspected it would not work. Not an application on their tool for such with 2004 truck controller. Not being able to modify shift points and line pressure causes concern. Engine is real strong. Transmission shifts like a wimp. I tried putting in update in Predator (don't even know if it needs an update) but a garmin pop up kept telling me must shut off firefox. I don't have firefox in this computer. Just in case I restarted desk top computer and tired again. Same deal. Where do I go from here? Ship the Predator in for fix? what is your suggestion? Chris at Hotwire could not help.

[mikel]

Honestly, I do not think there is anything amiss with your Predator.

We have to keep in mind that the Predator was designed for a stock Ram, and may not always play well with swap vehicles, but I have tons of people using them in similar applications.

He said there was nothing inthe strascan to do tire size on an 04 Ram?

[speedy912]

Remember, I'm a confessed newbe to this stuff. More years experience with Hemi engines than you have been alive but new to this computer controlled crap. Second remember, my predator is U-9000. Not one you have even mentioned before. Please don't tell me there is nothing that can be done. What is strascan The mechanic used what he called a DRB3. This is the same tool he used to do a computer update just a few days before. What model number Predator are the tons of people with out problems using? Why am I blocked from transmission adjustments because no tire size entered? This cannot be normal!

U-9000 is the generic part number for the physical tool. Dealers stock that and then download it with whatever firmware for the car they're selling it for. My SRT8 uses a U-7135 tool. If I had bought it from a dealer they would have taken a U-9000 off the shelf and loaded it with the U-7135 firmware and then it would have been a U-7135 tool (I think that's how that works).

strascan (Mikel can't type) ==> Starscan, which is the official Chrysler tool used by the dealerships (they can be had privately for something around $5000) Will hook up to the diag port and the internet and you can reflash any module, run any diagnostic, reset procedures, calibration procedures, etc., etc.,

The last part I'm guessing at... Unexpected Transmission Control Module. The Predator reads the current parameter settings. It's probably unable to do that with yours and it gets stuck?

[speedy912]

OK. How can I get it unstuck? Obviously, the Chrysler product dealer cannot help me. Do you suppose a connecting to support through computer could help? Do you think one of your dealers could fix the problem? Should I sent it in for repair? I'm willing to do any reasonable thing to fix the problem. However, if as you suggested previously, this may not be fixable then my only choice becomes give up and go back to a distributor & carburetor engine.

Chris at Hotwire could not help.

What did they say?

[speedy912]

Looking into problem. Awaiting response. Looks like I irritated Mikel and he has quit responding. Who do I look to if Diablo employee not willing to help? If I am the only person in the world with this problem, there must be a defect in the tool I purchased.

Forgive my ignorance here, but I was under the impression that a U9000 was a new unprogramed unit. I thought that the U9000 had to be flashed to become a U7135 or U7134 or whatever. Just a thought???

Ok... So Chris at Hotwire has experience whith this? How about waiting to see what he says?

Irritate Mikel? You? I'm not sure that's possible. There are a lot of people way more irritatiing than you working on Mikel. You'll have to try harder.

While Diablo might find your project interesting I suspect it's pretty low on the priority list. You have a completely non-supported application/configuration right? You're probably going to have to do some of the legwork and trial and error yourself. And then you may discover it just won't work. Sounds like Hotwire might be your best hope for suggestions at the moment.

You very well might be the only person in the world with this problem. Can you name any others with exactly your configuration trying to do what you're doing? Even if you manage to do that it's going to be an unsupported configuration and there are hundreds (maybe thousands) of other people with supported applications in line in front of you.

Tool must be defective? Ummm, yea. Try it on a car that wasn't built "one piece at a time" (Johnny Cash) first.

[mikel]

Agreed.

Plug this tool into a HEMI Ram, and tell me it wont change the tire size, then we have a problem.

Its not that I dont want to help, but telling my engineers it wont change tire size in a vehicle with a swapped engine/tranny/PCM/TCM/Harness will get me nowhere.

I still feel there is nothing wrong with the tool
What you have to understand is we spend countless hours reverse engineering these systems in the OEM vehicles, and when you start swapping things, and do not include each and every module that came on the donor car, you can/will run into issues/

Now, as I have said before, there are easily hundreds of swapped HEMI vehicles running around with our tuners in them (proof of that was seen everywhere on the SEMA show floor last year), the question is, what did they do differently than you did?

[speedy912]

What part of NEWBE was not understood. I'm trying to learn and I really am not trying to irritate anyone. Just want to get to bottom of problem. For Mikel; I own two Durango with 5.7 unmodified hemi engines. One 2004 and one 2005. Will either of these work as test bed for tire size? If not, I am sure my friend with dealership will let me try a truck as soon as he has a used one in stock. However, who knows how long that might be. Over the last few days I have learned the u9000 is not a programed unit and is on dealer shelf for programming to desired vehicle. Don't know what the number for 2003-2008 truck is. Talked with Diablo dealer this unit purchased from today and he suggested loading stock tune then attach to computer for 04 revision. Going to try that this evening. Chris at Hotwire has not indicated he has experience with this.
