WH Grand Cherokee 5.7 tuning options

[Robzilla]

Hi all,

New owner here with a 2006 GC 5.7.
I've been trying to research if there are any handheld programmers available, but most of the discussion I'm finding is at least 2-3 years old.
Features I'm looking for:
- Tyre size correction
- Error code reading/resetting
- Flash tunes (like the options in a Flashpaq)
- TPMS disable (bonus but not required)

Is there anything available on the market that can do this?
A Flashpaq would be ideal but seems like a grey area if they supported export WH models, does anyone know if this has changed in recent years?

Cheers

Flashpaq 3872 owner right here!

Changed tyre size to 33"
Clears codes
great 95 octane tune that brings the hemi to life and a lot better throttle response
Better fuel consumption

For TPMS disable, theres an app with Bluetooth dongle for $30 that does it. Cant remember its name, JJeeps or something like that?

Does everything Slippery mentions.
Superchips added TPMS disable in a firmware update a few years ago... updating the device is pretty painful (or at-least it was last time I did it a couple of years ago, and I doubt the software has improved.), but does work.

I've had a few incompatibilities (most-likely due to the export.), but always solved by Superchips support. Which typically involves plugging the device into USB, sending 'calibration data' to Superchips via their rubbish/out-of-date software, and waiting a week or so for them to issue an update.

Dunno if the newer devices have better or worse compatibility though.

Thanks for the info, just what I wanted to hear!

Will start the hunt for Flashpaq.

I disabled TPMS with Jscan. JJeeps was close


I think one or two of the valve sensor batteries are flat. Probably will fit new sensors when we get new tyres. That's a long way off though.

Another excellent app is ALFAobd

You can change tyre diameter and gear ratios for speedo calibration with at least one of those apps.

$50 per vin license, for JScan full access.

$50 for ALFAobd which appears a one off fee, not per vin.

Another vote for the Superchips... however I'd recommend not using the F5 version (3874) as I could not get it to work on my car, I found a used 3875 on Amazon in the US which has worked fine.
