Much needed ADVICE!!

I am new to tuning, I have a 2011 Camaro 3.6L and I am trying to setup VCM Scanner to start data logging but I am getting very confused with the so much information on you tube and all the forums I can't seem to find what I'm looking for or if i have i don't realize it. I am using Goat Rope Garage's layout in the scanner but when it comes some of the graphs i cannot find the map sensor but instead i found intake map sensor. Do i use this instead. Same with the Cylinder Airmass sensor, i cannot find airmass sensor instead i see under the math maf cylinder airmass for different cylinder now i am assuming if i need to use this i would pick the 6cyl since it is a v6. Also in the vcm editor i don't see some of the tables i see in other videos, again i am assuming (and you know what they say about assuming) that is because of the different engines like the lfx and llt. and yes i am in advance view. I don't see anything under the os tab like there just a blank screen that says OS. I have attached the tune that i read from the car in the beginning and a log file. If someone could just point me in the right direction i would greatly appreciate very much. OH YEAH one more thing on the VE Graphs i cant get the pressure ratio to log either. <<<<IM IN NEED OF DESPERATE HELP>>>>

For the MAP sensor, when you see "Intake MAP Sensor" in VCM Scanner, that's the correct one to use for logging manifold pressure. It's often named differently across platforms, but it’s the same thing. So, log "Intake MAP Sensor" for your pressure readings. The "Cylinder Airmass" should be logged using the "MAF Cylinder Airmass" parameter for the 6-cylinder engine, as you assumed. This value is crucial for calculating fuel and spark timing, so make sure you have the correct one selected for your V6.


Now, for the missing tables in VCM Editor, it’s possible that they aren’t present due to differences between the LFX and LLT engines. Certain features or tables might not appear for your LLT engine because they're either locked or not available in the factory ECU. To ensure you're viewing all available tables, make sure you’re in Advanced View in VCM Editor. You can enable this by navigating to the Edit menu, selecting View, and checking Advanced.If tables are still missing, it might mean that these parameters aren't available for your ECU, or they require more advanced tuning setups (such as a custom operating system with HP Tuners)
Regarding the OS tab being blank, this is normal. Unless you’ve applied a custom operating system (OS), this tab will not display anything. Custom OSs are used for advanced features like speed density tuning or forced induction setups, which you don’t need to worry about right now.


As for the VE Graph and pressure ratio, if you’re unable to log the pressure ratio, ensure you have MAP and Barometric Pressure both logged. The pressure ratio is simply the MAP divided by Barometric Pressure. You can create a custom math parameter for this if it’s not automatically calculated in the layout you’re using. In VCM Scanner, go to Math Parameters, and you can add a new one where you define Pressure Ratio = MAP / Barometric Pressure​.


To get your basics right in VCM Scanner, here’s how to set up your sensors and get started with logging:

1. Connect your MPVI2/3 device to the OBD-II port and launch VCM Scanner.
2. Select "Channels" and make sure the Intake MAP Sensor, MAF Cylinder Airmass (V6), RPM, and Throttle Position are logged by clicking the + sign and searching for these in the channel selector​​.
3. If you want to customize your layout, you can adjust the graphs or histograms under the Graph vs. Time panel by right-clicking and choosing to add or edit the displayed parameters​.

For now, start by logging these basic parameters (MAP, MAF, RPM, Cylinder Airmass), and once you have your data, you can gradually add more complexity to your layout. If you feel overwhelmed by custom layouts like Goat Rope Garage’s, consider starting with the stock layout in VCM Scanner and building from there as you gain confidence. As you get more comfortable with data logging, the advanced setups will make more sense. He also sells his VCM Scanner layouts on his page if you click on his bio!

Thank you. I am in advance view and logging the intake map but I am getting 0.00kpa's is this normal. and could this be the reason why I'm not getting pressure ratio? I will attach the tune, log, graphs, and channels files that i am using. Would you mind looking it over and letting me know what I need to change and the reason behind changing it. I normally catch on quick to stuff but I am confused. I did purchase the layout that Goat Rope Garage uses but again I'm not sure where I am messing up to get the data in the graphs.

there is no map sensor for the 2010 and 2011 LLT enignes in the camaros. 2012 gm went back to having a map sensor. these ecus are maf and o2 only.
