I am embarrassed to have to ask and have googled it but seem to be blowing that.

I use HPTuners an d running the latest version.

I have never tried it on a vehicle with no license or credits.

I have a friend that has a 2007 Silverado with a rough running engine.

I want to offer to run diagnostics but have never presented myself with the no-credit scanning. I think he may have mishandled his plug wires. Can I run diagnostics and see which cylinder if any is missing?

Thanks

 

The scanner works without licensing the pcm. Its when you want to edit the tune file you have to license it.

 

None required to read the tune or use the diagnostic part of the tool.

Only to change/modify and reflash into a vehicle.

 

Thanks Guys

 

Back again and just in-case, are there any enhanced or custom diagnostics configs available or will the default config be enough.

Thanks

 

Not really, if there is anything you want to see that isnt in the default you just have to add it to the table display.

From there you can put it in the gauges or a histogram.

Note that the STFT and LTFT won't be up in the histograms on a GEN 4 motor, as the default is setup for a LS1 motor. That can be changed it needed.

 

Thanks,

Its a 2007 Silverado truck so I'm good to go.

 

Hi Guys, I would like for someone to have a look at this scan if I could.

I ran the scan. I used the default imperial and added all 8 misfire PID's so we could see them live.

Please forgive my inexperience in the matter.

The truck is a STOCK 2007 Silverado, 150k miles, it has a miss, according to my friend, most noticeable @ idle. I could feel the miss. We did not drive it. It was on a break at work.

I could see Cyl #1 missing often and an occasional #2.
I see it resets the total misfires often, not sure why.

He is chomping the bit to change the wires but I asked him to wait because I wanted to get other opinions, as it may be an injector?

Attached is the scan and the config.

If we need to tweak the config and scan again please let me know.
If I need to make a new thread of this I can if needed.

Thanks,
