Cal can you start a new thread for everyone to post up their installation, comments, tips, and hopefully not, but also problems. I was going to start the thread but I know it will get maximum attention if it's from you. That way we can all learn and benefit from others. This will be completely new for a lot of us. I'm nervous, excited and a little intimidated about the learning curve to understand the XFI.

The kit is designed to mount the adaptor box where the stock computer was and run the harness to the Sportsman out the top, behind the glove box (just release the little clip on the upper left of the glove box door, and it will open farther). The Sportsman computer will fit in a cavity to the left of the glove box.
It doesn't have to be installed this way. I know some have mounted it to the back of their AC delete plate (if equipped). Others have set them inside the glove box, etc...
Our GNS Glove box mount would work Great for mounting these...http://www.gnsperformance.com/interior-g-body

Thanks Scot, I saw those. Designed my own that fits in a different way. I'm guessing there is plenty of room behind the box area to mount this as yours look quite a bit larger than mine. (First time ever saying that! )
Man I'm loving this Sportsman!
Glad your liking it... With our mount the actual glove box is removed from the door and our mount attaches to the door... You can Still use ours to store registration papers and such under our bracket, it's not gone 100%.

I'd be lost without my glovebox. There's not many places to put stuff in these cars anyway! If it was strictly a race car I would do one of your brackets

The Spokesman fits nicely in the owners manual slot.

Anyone had issues installing the software program in a laptop?

I have 2 Sportsman units and the USB supplied will not load the program into either of the 2 laptops we have tried.

Both laptops are used only for FAST programs, Classic, XFI, XFI 2.0, and also the Powerlogger, so we are not complete idiots tuning with these laptops.

One laptop is XP, the other is Vista.

The Sportsman download from the FAST site will load on the laptops, but will not connect with the Sportsman computer.

Any help is appreciated.

Not sure what Cal and my buddy doing the tuning discussed how to get it loaded on the laptop, a phone call rectified the situation, and the car now runs!

Thanks Cal, this is probably number 100 of the many times you have assisted us

When you installed your alky, you ran a green wire into the car. That's the MAP signal to the alky. You will need to "T" into that wire abbr connect to the center green wire on the MAP connection by the adaptor harness. BE SURE TO MAKE GOOD CONNECTIONS! This is the signal for all the fueling and timing of your engine

The laptop programming issue was easily solved by Cal, and we finally were able to do a road test as it was 100 degrees for the first time in over a week as it has been 110+, and no road tests are done at that temp!

Car ran ok, but shortly on the road, an error code for the O2 came up and the values were not normal?

After another hour checking the wiring with no improvement, a call to Cal he said check to see if the O2 was heating like it should, that proved to be negative.

I ordered 2 units, so it was a simple fix as the second harness and ECM was installed and the problem was solved.

Over the years many aftermarket items may have bugs like this, and I am so grateful for Cal's tech support and expertise, as well as standing behind his products! :)
