E67 HPtuner 2 Bar OS

It appears that the 2 Bar OS has all
Engine Diag/Misfire/ values set to 32,768 max without edit option. What is the reason for this as compared to a non-2 bar OS for CTS-V2?

Likely because it isn’t something that would be used on a stock cam car but I believe it should work if populated with the correct values as long as the MAF is enabled. SD will disable misfire detection.

I am running the 2 Bar blended. All the values are greyed-out? Meaning it will not allow me to make changes. I never knew that SD disabled misfire, interesting.

Maybe a software version difference.

Either way you can always load a stock OS tune if you are chasing a misfire.

I see misfire tables on this custom OS. Maybe you are not in advanced view.

I am in advance view, it's possible there may be a version difference from the time it was released. Car is running excellent, no misfires. I just was curious? Thanks for the response.

Are you on version 5? If so, did you go through the class and register the code to unlock the additional features?

yea as above ^^^ if its greyed out u may have to do the hptuners test online to enable the emission features for the version 5, its easy to do and gives u a key to enter

I've read a little about that, v.5 still seems to function similar for me at this time. However, the relentless campaign to force every aftermarket business into bankruptcy never sleeps! Maybe I'll just keep what I have and disconnect from the internet all together, like an old school burner phone. haha

I'm sure newer vehicles will suffer in the performance aftermarket world underground. Something to be said just keeping what I already have.

As far as the E67 ECM is concerned and the 6L90 T43 too there is nothing in any version past 4.8.7 of use. The only problem would be if your interface is MPVI3 which will force you to use version 5.X

I'm still using 4.10.7 and was forced into a MPVI 2+ with Pro Features as my old Laptop died. I had to upgrade to MPVI2+ because my new Laptop has Windows 11 and the MPVI1 isn't compatible with Win 11.

Windows 10 here

I started off with MPVI2 plus Pro Link for my WB and FP gauges, lucky timing with Win10, guess its fast becoming a legacy item, I'll just sell it along with the car as a package.

Yeah, I didn't have a choice.

kittyboy- If you are on V5, are you able to see all of your DTC's? If any are greyed out that might be your issue and it may be why you can't see the misfire tables as the software is still locked out.

Never thought of that, I'll definitely take a look.

UPDATE: 11/27/22
HPtuner v.5 did not automatically update my Misfire values and disable Misfire, I was incorrect, I had changed them myself previously and forgot. However, HPtuner v.5 will not allow previously entered values to be changed in Misfire, the edit option is disabled. There are other DTCs greyed-out as well.

Thanks @PGA2B

I guess if your not in the tuning business, may not be advantageous updating to v.5?

I went ahead and registered the HPT course and re-installed v.5. I figure I'll just make myself an easy target for prison life, I hear the food has improved and free health care. Maybe an opportunity to start a side-gig remote tuning. haha Just think, tuning in prison.

Did it unlock the DTC's? Since our platform is no longer supported with new enhancements I'll stay with 4.10 for as long as I can.

Yes, unlocked.

Future HPT software v.X updates will not have practical improvements as they pertain to CTSV2. I updated so that I can benefit improved enhancements with regard to user interface.
