Thread: DoD Questions

I believe I asked this before, on the deceased GXP, and never got an answer.

I'm getting, at best, 21 MPG, and I can't remember the last time I saw a cloud of oil smoke. Is it possible for the DoD to turn itself off?

And i know I "shouldn't," but if I wanted to, how would I go about diagnosing the problem and reactivating it?

The only check engine light on is a vacuum leak, but it was behaving the same before that happened. I've never really been able to fell/hear it, even on my Monte Carlo, where the DIC told me which mode it was in.

What sort of scan tool can I use while I'm driving?

Bump.....

Where is the ign coil number 7 located on a 5.3L LS4?

Cylinder 7 is on the front bank on the far right side. 1/3/5/7 left to right on the front side.

Anyone got an answer to this question?

"At best" means "45 mph in fourth gear on a surface road." Average is 17 at best. I used to average 22 on my LS4 Monte Carlo, which had the decency to tell me which mode it was in. Why that feature is missing from a more expensive car that is higher in the GM hierarchy is a mystery that will never be explained.

Can anyone tell me the name of a scan tool I can use while driving? And what I should look for on that scan tool?

you could pick up a bluetooth adapter and download the torque application. I'm not sure if it will say you are in 4 cylinder mode, but the adapter is about 20 bucks and there is a free version of torque.
