-I have a stock "411" pcm from a 2002 Firebird Formula.
-That car is an automatic.
-I am buying a new, stand alone harness for a 99+ LS1 w/ T56 manual transmission.

I know that the stock '02 Formy tune won't work since the transmissions are different. But I have a tune from a 2001 LS1/T56 car saved on my laptop. I will be registering the '02 Formy VIN/pcm with new credits so I'd be able to alter that tune.

My questions...

1. Once the pcm is swapped to a new car(88 trans am), with No BCM swapped as well, can I still access it like normal and write a calibration to it?

2. Can I just do a "write entire calibration" using the '01 LS1/T56 tune I have saved(not locked) onto the '02 pcm with no specific changes to address the trans difference? Basically, will a write include everything needed to tell the pcm that the car no longer has the 4l60e?

It's been like 5 years since I've messed with HP tuners so I forget.
