i have 95 lt1 caprice i need to tune it and i plan on using tunercats rt program what do i need for hardware.

Am i going to have to solder in a port in place of the chip.
or can i buy one of there adapters if so what one?

If i buy the autoprom assuming this is what i need and i'm not confused?
do i need to buy the cable2 since the 95 uses the ob2 style plug?

If i buy the cable2 it comes with the aldl to usb adapter that i assume i can use to datalog and check codes like a scan tool so its something i need any way right?

Sorry for all the questions but i need help soon as i need to order the stuff today.

Also my pcm has no part number on it anymore how do i find what i need for a definition file?

Thank you very much!
