So even though it shows that it did not save my tire size, it still saved what I put in?

I have the latest update, and now my speed calibration parameter won't save my tire size. I have tried doing it by tire height, and by width, aspect ration and diameter, and it never saves the information. I have a 2007 Silverado 1500.

Ok. I haven't updated in a few weeks. I am still running 1r01i.

It is engaging for sure. I have been monitoring it in engineering mode. Plus, you can definitely feel it turn on.

Well, DOD is still engaging even though I have it turned off. Any ideas?

Torque Management.

Just got through updating to 1r03i. Thanks.

Up until recently, I had DOD turned on, but it would hardly ever go into DOD mode while driving. The other day I turned DOD off, and it still goes into DOD, but stays on more frequently than it did when I had it tuned to stay on.

Also threw a P0171 code (System Too Lean Bank 1). I cleared it, and ...

Hell, my DOD rarely even comes on anymore, and I haven't disabled it.

Try a Dash Hawk if they still make them. I used to have one that did the crank relearn on my G8, when I swapped ECMs.

I know., which is weird. Once I get my Intune back, I am going to put the stock file back in and see what the issue really is. If it is still like this once I do that, then I know I need to take it to my mechanic to diagnose.

Use your tool to read the PID (oil pressure) and see if the gauge, is wrong. Is it the correct sensor, because if it is not indicating high enough oil pressure the DoD will not function. do you still have the old sensor, try swapping it back in.

I sent it back for RMA.

After I had the sending ...

Can I ask why you left DOD on? I get the same or better mileage than stock on my 08 vortec max running the 87 tune with DOD disabled. How many miles are on your truck and does it use any oil? Also, the tune will have no effect on oil pressure. Could it just be that you are paying more attention to ...

My concern is that DOD only works sometimes. I did the 87 octane tune, and left DOD on, so I don't know why it won't switch on now. It was fine for the first few days after I tuned it, but it seems once the computer relearned, it stopped working.

Also, I noticed that my oil pressure shows a bit of ...

My bad. I meant optional A/C, and 500 hp.
