MY trucks issues

[DarkFox1]

yea it is..

I dont wanna mess anything up tho...

howd you come across a 2nd pcm?

oh and this is for a 97 and up right? I have the gt-40P heads..

 

[CobraXP]

Mine is an early '97, with the GT-40 heads - but I don't think it matters - maybe someone will chime in a clarify.

Anyway - if it will work - you are welcome to come down and we will try it out and play with it for a day...

 

[DarkFox1]

thanks for the offering, if I do decide to do that.. it may be after christmas.. traffic here in disgusta is awful, I can't imagine what its like in ATL right now hehe.

if I did come by you could drive it tho and then you could really tell me if I'm crazy or not hehe.

 

[CobraXP]

There is no traffic in Atlanta - only one big parking lot. If you come from Augusta - you don't have to come to Atlanta, I can get you here way before there.

I have to work on the X this weekend, got some new O2 sensors and EGR valve to put on, plus a couple of other things... So if you decide you want to come, just let me know...

 

[DarkFox1]

yea uh, if you get a chance get on aim and I'll talk to ya there about it.

 

[DarkFox1]

hows it goin v8? any leads?

unfortunatley I wont be able to go to cobra's this weekend and I'm all out of ideas

 

[V8-X]

Well, nothing found so far.

Just received a call back from the Service Manager from the Ford Dealer I most recently took the X to. He spoke with the Engineer, which the Engineer didn't have any ideas or problems he could refer to.

So now instead of the Engineer looking at my X, the Ford Dealership is going to check for a 5.0 X on their lot. If/When they find one, the Service Manager stated they'll run tests side by side for each of the two X's and compare. Hopefully this will prove to them that there is an actual problem with the X, not my head! I suggested this to them before, but evidentally it took the Engineer's word to make them do this comparison.

This is all for now. I'll keep in touch regarding what the dealer finds, if they have a 5.0 X.

 

[DarkFox1]

good to see they're doing that for you.

I've been conducting tests with the pcm with the help of a performance shop. Turns out my PCM (XDT2) has a disabled service port, or something along those lines prohibitting it from starting with a chip (dialbo chip) and on an attempt to try another PCM (SLL3) the truck refuses to shift and has a very high stall in the converter, I guess thats electronically adjusted.

shops all say its fine, I even pointed out the really bad hesitation it has when its cold, shops say that "ever car does that" and that I should just "ignore it or get a newer car"

so.. I'm just going along assuming all Xs/mountys are exactly like this one from now on, unless I find another lead to follow.

 

[V8-X]

Sounds like the typical shop tech that only tests via the computer. Nothing is checked by hand these days, so a misreading sensor may never be found. Which I believe it has to be either some sensor or the PCM itself. I don't believe any car/truck should act like this, all the people that I know that have X's don't have this problem. So how can it be normal? Keep me updated DarkFox1, and I'll let you know what they find if they can perform a comparison test. Good luck.

 

[GaSouthern1]

you should come to Rozier Ford here in Statesboro Darkfox, they seem to be a reputable dealer and it seems like they will take care of you. Just an idea.

 

[DarkFox1]

I've been meaning to go down to southern just to take a look around, a lot of my friends have been considering transfering there and getting out of this town.. 1 of my friends currently goes there.. although hes takin a break, he drives a GM so he wouldn't know anything about the dealer, but.. I suppose if they wouldn't mind checking it same day I could try that later on.

I'm about ready to give up again, can't do any mods w/o a chip, and the chips wont work, so theres no reason to even try and upgrade, and since the shops can't find anything thats "broken" to repair.. for now at least I'm gonna hafta just put up with it..

Solder in the jumpers and a chip will work.

Don't give up so easily.

aldive, i have heard that this is all that is needed to "re-enable" the service port. is this really true, or was someone pulling my chain?

Yes, to the best of my understandingl; I, however, do not have personal experience.

There have been discussion on the actual procedure on these boards.

 

[DarkFox1]

my pcm board appears to be covered in some kind of jelly, I guess its an electrolite or something to protect the board from the conditions it gets from being in a firewall?

by looking at it through the service port with my trusty maglight, it doesn't look like its even as complicated as the board you find on CD-roms.. interesting that such a "big expensive part" is as simpler than a CDrom.

I'm no expert on soldering, but,we dont even know if Xdt2 is the real code, since the truck was reflashed back about 2 years or so ago.

Every time I attempt to do something with this thing I'm met with opposition, giving up is certainly the most cost effective way. but as it has been so far.. and the reason this post was started to begin with.. it will slowly annoy me to the point that I complain about it again.

I'll give the local guy a call later on today I suppose, he generalizes the X with "truck/suv" too often, hes a mustang guy and assumes that a 5.0 bronco part will fit on a 5.0 X.. which.. you and I know wont (in most cases) like bassani headers and kenne bell chargers.. whats even more odd is his mother owns a 98 mounty that he drives often.

.

You need to remove the protective grease and clean the board contacts prior to installing the aftermarlet chip' this of course is after fixing the jumpers.

The dealer can read your box code for you.

Good luck.....

Most any place that sells the chip can also read your code from your PCM. I know SuperChips will even solder the jumper wire at no charge and promisses 24 hour turnaround. I also think Brian (Apten) will solder the wire for you. He also probably has a way to read the code. I had Ford read mine since they were the idiots that reflashed my PCM and didn't put the new code on it as the TSB instructed them to. In your case Ford will probably want to charge you an hours labor to read it.

 

[DarkFox1]

yes brain is willing to do that, he's been very helpful as I've talked to him for a while via email about the issues.

the issue comes with that that I would need a replacement PCM for that to work.

he sent me one.. an SLL3.. but upon putting this pcm in the truck, the truck no longer shifts and has a very high stall on the converter (around 2200 rpm)

I have emailed him about this but I suppose hes been busy, as there has been no reply yet, I've got it all packed up ready to go back to him.

Has anyone suggested the coolant system temperature sensor? Not the one that sends a signal to the temerature gauge, but the one that sends the temp reading to the engine computer.

If your computer thinks the engine is too hot it could give you the problems you have. Idling high, weird shifting, loss of power, etc... are all noticed when the computer is trying to get the engine to cool itself off.

 

[DarkFox1]

well the oddest thing I noticed when I popped in this SLL3 PCM, the engine idled at 500rpm.. given the truck was considerablly warmer but.. after switching out to the XDT2 it idled at 700-1000 again..

would this temperature item as you mentioned cause problems with the temp guage in the cluster? cos it seems to be working perfectly on my truck
