CMP retard no reading

[rayhawk]

So I have been getting some intermittent check engine lights on my 97 2 door k1500 tahoe, and I decided to check my CMP offset, but I can't get a reading. I followed the setup advice on my torque app, but still no reading. I'm getting a p1351, p0327, and p0161 right now. The truck runs fine, but I would like to sort this out. Any ideas on why I can't get the CMP offset to read?

Do you have to buy additional capability with that scan system to read CMP offset?

I've never worked with it. I read multiple threads about folks with software-plus-connector cable (or dongle) scan systems, and can't get them to work right.

I use an actual scan tool instead of a scan tool simulation.

CMP?
I thought CMP stands for Civilian Markmanship Program.

RPM needs to be above 1100 rpm, I believe. Probably won't get a reading at idle RPM.

I do with Dash Command, useless as it is.

I never could get Torque to read CMP.
Dash Command worked but you need to pay $9.99 for the extra GM PIDs.

I didn’t mean Dash Command is useless, far from it for a mere $20.00, I meant reading CMP at idle is useless. FTR

Ok thanks, I'll try Dash Command.

Anytime.

Dash Command worked, I'm at -4 degrees.
