    I tried re-scanning for parameters with 4.1.064 and it did not find any extra PID's. Still the same 5 exhaust valves ones but I still did a datalog. Not sure if this will help.

    Debug.dat is located in \Documents\HP Tuners\Settings
    You can get an infolog by hitting the blue i button in editor or scanner.

    I was only able to locate five of the parameters you listed above. Just emailed a 26 minute log showing all four driving modes.

    0:00 to 6:xx = Tour mode
    6:xx to 12:xx = Sport mode
    12:xx to 18:xx = Track mode
    18:xx to 26:42 = Snow/Ice mode

    Hope this information is helpful to you.

    I believe I've located the issue affecting those extra scanner parameters. Please download 4.1.072 and give it one more try.
    Thank you for your help and patience.

    Yup I see them there now, I'll get a log for you as soon as I can. Do you need me to cycle through modes at all? Typically I drive in Sport.

    I would just monitor them as you drive and take notes as to the values each of the extra 4 pids indicate. It should be pretty obvious how they are used after a drive.
    I will relabel everything accordingly once I have a log.

    Took another scan for you this evening with all nine of the parameters you requested, and emailed a log showing all four driving modes.

    0:00 to 5:00 = Tour mode
    5:00 to 10:00 = Sport mode
    10:00 to 15:00 = Track mode
    15:00 to 26:42 = Snow/Ice mode

    Hope this information is helpful to you.

    Could you possibly upload that log to here so I can check it out also since I don't access to all 9 PIDs.

    Thanks a lot for the help. This makes things much easier.

    Based on the log you submitted, regardless of driving mode selected, the car is using just one "performance mode." It indicated mode 1 throughout the entire log, so you only need to modify Exh Valve Close % 1 and Exh Valve Open % 1 tables. A value of -1 in these tables means the valve is fully open.

    Your RPM thresholds are in the Exh Valve RPM Thresholds table. Again, only need to change Close 1 and Open 1 rows. Just 3 tables to edit.

    Hmm interesting. My car seems to be using the Exh Valve Close % 2 and Exh Valve Open % 2 tables based on what i've seen from just the 5 PIDs I have. Wonder if that means my car uses Mode 2 then. Wish I had those extra PIDs just to make sure. I'll start changing the Exh Valve tables and see what happens.

    Are you both sure you weren't controlling the exhaust using Driving Modes ->Engine Sound Management with a fixed setting other than 'Auto'. Maybe one was Sport the other Track. Just a guess as I would think the values would change.

    I took a datalog last night but only 2 of the 9 tables were reporting anything, which is strange because last time when I only had 5 PID's all 5 reported something. I think I need to re-poll again on the .072 version then take another log. I can probably get one this evening.

    Yes, you likely need to repoll.

    Latest beta 4.1.083 should have the extra pids available for FSCM_F (Camaro among others) guys as well. I'm not 100% sure they are correct so would appreciate it if someone logged them.

    Ok so all 9 PID's show stuff for me now. From just switching modes in my driveway it looks like
    Stealth = Mode 3
    Tour = Mode 0
    Sport = Mode 1
    Track = Mode 2

    I'll get a log of them while driving later.

    I was able to see everything after a re-poll. Here is a datalog from last night.013.hpl
