2000 TA LS1 Flashing - Is there a list of compatible USB OBD2 adapters?

[Pdiminico]

Hi All,
I am new to Tuner Pro for OBD2.
I have a 2000 TA LS1 which I would like to flash for changed rear gear ratio.
Is there a list of compatible USB OBD2 adapters which I can purchase?
Thank you,
Pat

I would like to flash for changed rear gear ratio.

Gear ratios into tranny relates to gearset installed into it -how can you change them by reprogramming ?

No, I will install the 3.42 gears into the axle.
My current gear ratio is 3.23 and I will swap in a gear set for 3.42.
The question of flashing the system for the new gear ratio.
Will there be any specific areas in the BIN which will require changes besides the "Final Drive Ratio" ?

I think its mostly for correcting speed info into digital bus
Trans itself working based on speed sensor that count prop shaft revs and not wheels
