2012 CTS-V throttle hesitation

[Tim]

Howdy,

I've a stock 2012 CTS-V Coupe manual 6 speed trans.

I have loaded the latest update to my trinity, and attempted:
Diablo tune -Check engine light and throttle non-responsive or significant lag. Engine also sounds a little rough.
91 OCT and Pulley tune: No check engine light and hesitation on 1, 3, 4 gears is noticeably less. In 2nd gear below 3k RPM there is a significant 2-3 second delay in application to the pedal.

I am using the Trinity_gm_can_gas-1r13x_update.crom from 2017-05-17.

Thoughts, 1st steps?

can you let the tool read the backups from the vehicle then export them with dsdownloader and post them here please?

[Tim]

I don't mean to be overly difficult, but perhaps I'm missing something. I am using the DSDownloader tool 2.5.0.14 and when I attempt to use the "get" function in the Trinity Browser to pull the log file I get an error that states that exporting files is not supported in this tool..... ?

Am I missing something? I've looked through the help and nada on ideas so far.

what we are looking for is the backup file it read from the vehicle.
Connect to dsdl, click get tune file from tool, and select the option for backup and post that file here please.

load this update to the tool using dsdl then you can reload the tunes and they will be correct.
You;ll need to restore the stock tune first.

Thanks

Well, the throttle hesitation is now more consistent, however it is still there. Now its exactly the same each time.

[mikel]

what does the device report for options/show info, version?

Thanks

[Tim]
