    Default Tweaking with HPTuners

    To those that are experienced, please chime in with some pointers or feedback. Also, anyone know how to load the data bit up for logging our shift times? I'm posting up my tranny tweak file, stock file, and a log that I took during the tranny tweak road test (albeit it wasn't logging any tranny parameters).

    PS - Charlie, you think you can add the .hpt and .hpl for attachments?

    BTW - SOTP, I didn't feel a difference.

    YES. We need this. I have been meaning to have them add this format for a while but I am lazy.

    First, I'm not an expert in that I don't do this for a living.

    Try disabling power downshift TQ management. It takes the lag out. It's not hard on it at your power level.

    You could raise the shift pressures by about 20% IMO. Also you only adjusted the normal desired shift times, I'd do special and downshift too.

    Good luck.

    PS: I'd like to see attachment support too, as long as tunes aren't posted that were paid for.

    Steve - How big can we upload as well? I want to say the standard .hpt file size for our car is 3.3Mb and the max .hpl that I have seen is 1.7Mb. Since I have seen very few people here even discuss HPT tweaks, I don't think it'll kill your server.

    Hey Boomer, I see your posts all over HPT forums in regards to the G8. Do you have any input as far as my tranny settings? I'm waiting for my WB bung to be welded in so the ECM is off.

    Default G8 HPT File

    Here is a copy of my G8 HPT file. Would say it is anything special but the trans works great. Changed all the shift points and properties. Worked very well on a second G8 I loaded it on. If you drop the shift times to .15, it will rip into 3rd also. Wouldn't change any of the pressure as I haven't seen a need. You can change the shift speeds enough to make it violent.
