Darn, thought that might mean it could read all the other codes too
The OBDLink offers a "GM Enhancement" for another $79.
There's also mention of another freebie called "GM Mode 22 Scan Tool by Terry" but I can't seem to find a description of it anywhere, just a bunch of places to download it...

 

[SunlitComet]

1. It does but mode 6 capability is ussually not included in most software becuase a one fits all does not really carry generic mode 6 info. The variables changes from maker to maker. It may support it but there was no list of whats covered for GM or is it another module to buy?

2. That gm enchancement was the one I recomended with the ScanXL Pro.

3. It is a really basic data displayer and dtc reader took 2 minuts to download and install.

Hey, so you have already played around with the "GM Mode 22 Scan Tool", guess it didn't get ALL the info huh?

I'm starting to lean towards the ScanXL to start and just order the "GM Enhancement" later if we don't get all the info we're looking for.

Check this out, I got a response back from someone at ScanTool:

"The transmission usually sits on the same OBD bus as the ECM. However, you are probably not going to have access to ABS, as that module usually sits on a non-OBDII bus.

OBDLink does support some additional commands that let it access enhanced ABS and transmission trouble codes, but these commands are only useful on newer GM CAN vehicles.

I would shoot an email to PPE with your vehicle information, and see what they say."

I don't know who PPE is yet (perhaps Palmer Performance?) but hopefully they too can help figure out just how much information can possibly be pulled out of this '97 Yukon

Demoed both mode 22 was very basic info plus o2 sensor voltages. Still going for ScanXlPro and the gm add-on myself when I have the money.Just ask PPE for details They are palmer performance engineering. Just6 remember I believe the gm add-on was required to look at the cam offset issue that came up so IMO it would be needed any time the distributor is moved.

Sent them an email earlier this morning, hopefully we'll find out pretty soon. Should also a good indicator of what the support will be like...ain't it?

Just some additional info on my setup and some that I've seen to give you guys something to look at while we're sorting this all out

I'm running a Xenarc 700IDT In Dash 7 inch VGA Touch Screen display that I used on a previous install, had it installed in the CD pocket of a NBS Chevy Z71, totally stealth install, looks like this:

There will be a slot load DVD drive like this one installed in an undetermined location

Using the Scorpius P20 2.4 Ghz Wireless Keyboard With Joystick Mouse:

Still gotta dig the info on that MCS case for you guys. It's a pretty slick setup specifically designed for 12v automotive applications. Gonna drop a couple gigs of ram and a 100gb hard drive loaded with music, music videos and movies

Carputers or carPC's have to have a "front-end" software to make them car friendly for the little screens and touchscreen applications. I'm probably gonna go with Streetdeck, Centrafuse or Riderunner
I'll also have the GPS and Rear Back-up camera in place and maybe a webcam...maybe

Here's some pics of installs I've seen:

I'll have to dig up some pics of my last couple of carPC's for you guys. Pretty sick stuff, kinda getting excited just talking about it again

How much does that little handy screen cost?

( i would probably find a omni antenna to hide some where to pick up wifi on the go ;D )

 

[gulleyman]

I think I paid about $400 for mine new, that was the most expensive part by far. You could probably pick up a used one for about half that though, maybe even less. The wifi is already built into the PC Case too lol. The last one I had actually would do traffic cams in real time through the GPS program
It was a pretty slick set-up, came ready to go right out of the box, just plug in and play and it was only about $650

What'chya think sunlitcomet, will this be enough to diagnose that random misfire?
