hi all, as the title says, i'm searching for a 1999 to 2001 corvette a4 bin. There is a 2000 m6 bin posted on here but looking for an a4 bin.

what am i trying to do with it - my swap has a 1999 ls1/4l60e dropout from an fbody, and it has a corvette servo. this makes the 1-2 shift way too harsh. breaks the tires loose at WOT every time, and snaps your head back at part throttle. I'm working on tuning some of this out and wanted to see how the corvette tune handles it, but haven't been able to find a stock bin from an a4 corvette.

thanks all!

Is there a particular reason you want a file from a 9354896 red/blue pcm? All of the vette cal's I have for that processor are for manual's.

Here is one for a 2002 vette auto 3.42 gear using the 12200411 red/blue pcm. Just fyi, it appears all of the manual files have all of the automatic stuff populated so you might just have to set the cal to 4l60e instead of auto.

Thank you, much appreciated! I was mainly just looking for a bin from an OS that has a well-populated XDF on here, so i could take a detailed look at what is done for the trans tune. So far i have found an XDF that supports a few OS's from 99 and 00, and of course the 2001 OS's are well supported with what's available here.

With regards to the manual tunes, I did actually look at some of them but some of the shift tables seemed radically different than what was in the camaro tune, which didn't pass the sniff test for me. However, that could just be my inexperience talking :)

Shoot, I should have added this at the same time. It's not a xdf but it still details everything in the calibration so you can compare to your files. Hope it helps.

greatly appreciated. i have been using this xdf: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?5894-2002-OS-12212156-xdf and it seems to work as expected with this bin.

One other thing - i re-did my trans tune using the shift times, shift pressures, and torque management values from the corvette tune and it made a HUGE difference in how the car drives. Part throttle shifts are excellent now. So thank you again for sending this along, it really helped!!
