I'm in the process of tuning my friend's 2001 Chevy Tahoe (5.3L) with an aftermarket alarm system.

The first tune I flashed to the VCM resulted in the alarm system becoming disabled. The remote...

As an owner of an '07 Avalanche (with the "upgraded" PCM), I am very interested in your progress. I've been trying to remove TM myself but have not been 100% successful.

Because the release of VCM Suite 2.1.16 enables the editing of DoD parameters, I have been spending a lot of time logging TPS and MAP (vs. RPM and vehicle speed) data.

IMHO, DoD on these GenIV...

I answered my own question.

Thanks for the quick reply.

Next question:

Do I need a wideband to log actual afr? I can get the afr commanded from commanded EQ.

In the VCM scanner, afr is sensor 120, or 121 I don't have...

I downloaded 2.1.16 last night. Some of the changes with the DoD and label copying seem pretty cool.

However, I'm still very interested in VE tuning my '07 Avalanche. I know the VE tables from...

I just downloaded the entire 20.8 MB .msi file in 20 seconds. No problems here!

The reason I posed the previous question:

I set up the function of a user-defined AFR commanded parameter in my table like this: 1/[PID.68] where PID.68 is the commanded EQ ratio. I set it up...

Is the AFR supposed to be 1.0?

That helps a lot! Thank you.

I'm starting to get it, even though I'm barely scratching the surface.

Thanks for the reply.

I must be doing something wrong. In order to use commanded AFR, I have to set up a user defined pid with the Air Fuel Ratio Commanded sensor.

The user defined interface...

I have an '07 Avalanche and am new to HPTuners. I do not have a wideband O2 sensor.

I was wondering if there is a sensor I can add to my parameter table that will allow me to monitor injector...

Thanks for the cfg.

I do not have a wideband O2 sensor or the Pro version of MPVI yet.

I guess I will have to save my money to buy more toys before I can SD tune; unless someone can explain...

I have a 2007 Avalanche and would like to take a stab at SD tuning mentioned in this thread.

I am a beginner with HPTuners but am comfortable with manipulating data in Excel.

Could someone...

I've attached a log file.

Because I have an '07 Avalanche I'm learning there is no VE table per se. These values must be calculated in Excel.

I just need a little help on what parameters I...

I'm trying to set up my default configuration file based on parameters recommended to me by other Chevy Avalanche owners. However, on my posted default .cfg file, histograms #3-#7 state they are not...
