Pettit ECU for Automatic
 

Can someone clearly explain if I can or cannot use a Pettit ECU for an automatic. I really have not seen any good responses in threads about the pettit ECU not being able to use in an automatic.

I did call Pettit the other day and asked them if I can use a pettit ECU in an automatic and they said they are interchangeable. Really?

Does anyone have one in anautomatic?
