Its a programmer, so you plug in a cord from your trucks port under the dash to the programmer. The programmer displays a screen that, after a few turns of the ignition key, will give you the option of Diagnostics, or your choice of three tunes (custom or preloaded). After selecting, you will be asked a few simple questions, and then the selected tune will program into your computer. Then, viola! Your truck is tuned.

 

You then remove it...

 

LMAO!!!!!!!!!!! ok then!!

 

then you jerk off on your steering wheel !

 

so the sct is a diagnostic tool also?

 

Y'up...it's also a generic scanner.

 

BONUS! I wanted a scanner anyway. Might just HAVE to grab one of these now.

 

I highly recommend this product. If I had to choose only ONE thing in my sig, I would choose the SCT...EVEN OVER THE ACTUAL TRUCK!!!

But seriously, this SCT )From hemifever with HIS tunes) are the best.

True story:

I was driving the falimy back from a camping trip a month ago. My check engine light came on. I was thinking it was an "engine too cold for too long" code. I have a 180* thermostat, so it runs cooler in the winter. But this was my first winter with the 180* stat.

So, I was getting nervous. SO I took out the SCt and did a doagnostic scan. Found the code and searched it on my iphone. "Too cold for too long." I was with the family and I wanted to make sure it was nothing serious. ALso, there wa the "MSD ignition" code which does not activate a CEL (code that says the coil #1 is bad...does it for all trucks with a MSD box in it).

Really good product and if you get it from Sean (Hemifever) he will take care of you. Basically he is just like us.
