I own a JEEP Grand Cherokee. What do I need to start tuning this

[ssnipes]

I got HPT for my cobalt SS SC

We now have a Jeep Grand Cherokee as well. Anything special needed to work with this, if at all? it is a V-8 318 or 4.7L

[ssnipes]

come on anyone.

[justin99]

I think you are out of luck.

[Bill@HPTuners]

nothing is currently available for these pcm's.

[ssnipes]

K so when will there be support. or will there ever be? I have a suite now and was anticipating this. thought I read somewhere that there would be in the future for dodge JEEP.

If there is already, I didnt see it on the website.

thanks

We have yet to release our Dodge software so its impossible to say when Jeep software will be available.

I thought they're allmost the same (at least 5.2L/5.9L/4.7L).

Which may be true, however there is no database as to what pcm's are in which dodge/jeep vehicles so knowing which ones transfer from one line, engine, etc. to another is very difficult.

Once we actually release our Dodge software we will worry about other makes/models & not vice versa.

Is there an ETA on this?

[ssnipes]

there has been alot of interest in HHO lately. we need PCM access. there is alot of people interested in obtaining software for compensating and maximizing their Hydrogen generators! New reason to have HPTUNERS? Increase MPG by 50% !!!

Thank you for your development efforts on the Chrysler motors, Bill. I've been coveting HPT for eons, but placed my order yesterday when I saw that you are well on the way with Dodge tuning. Beside the '06 GTO, there's a JGC SRT8 in the driveway that badly wants to be introduced to your product !

Cheers,

Any news?

[TonyB4]

I also have a Jeep Grand 07 with the 4.7 and am waiting patiently to tune it.....

I have LOTS of Dodge, Jeep and Chrysler parts manuals. Pretty much everything Daimler has released since the 80's. You are more than welcome to them all. Just drop me an email at info at alljeep dot com. They are all PDF's. In my experience, they don't change part numbers unless the item changes - not the application.

Now I'm looking at the 04 Jeep Wrangler, and there are 11 different PCM's for this year alone, or 6 for US emissions alone. 2 are for the Rubicon, so that leaves 4 for the other Wranglers. And I don't see where any of these transfer to any other rig, but the 04 Jeep Wrangler.

56044419AC - 56044419AD - 4.0L Manual Rubicon
56044421AC - 56044421AD - Export
56044422AC - 56044422AD - Export
56044433AC - 56044433AD - 4.0L Auto Rubicon
56044434AA - 56044434AB - Export
56044447AC - 56044447AD - Export
56044452AC - 56044452AD - Export
56044455AC - 56044455AD - 2.4L Manual Wrangler
56044473AC - 56044473AD - Export
56044474AC - 56044474AD - 2.4L Auto Wrangler
56044477AC - 56044477AD - 4.0L Manual Wrangler
56044478AC - 56044478AD - 4.0L Auto Wrangler

So it looks like the one year would have 6 different computers. Depending on weither it was auto or manual, or which motor it had or if it had Rubicon trim or not. The only difference that I know of between the 4.0 in the Rubicon and in the other Wranglers is the Rubicon is supposed to have about 20% more power than the others. I believe the PCM's will succesfully swap between them - as long as it was auto/auto and manual/manual.

...Anyway, sorry for the tangent

[99blackFRC]

I highly doubt they're 11 different PCM's for each platform. Probably just the config p/n for each OS/cal load.

Possibly, but I have a way to look up the part number and if it's application. If it's part number worked on several different applications, it would most likely say. None of those 11 showed any other vehicle but the 2004 Jeep Wrangler.

Give me another example if you would like and I'll look it up as well....

The Magnuson MP90 / custom intercooler / intake is done and awaiting installation.
The available piggyback systems pale in comparison to HPT.

got it for my '03 Olds Alero, and now need it for my '07 Wrangler X as well.

Bought mine cert. used but I think it had larger tires/recalibration that was removed before trading in. Speedo is off progressively up to 10 mph too high; at 80mph on the speedo, actual speed is a little over 70.
