Modded ECU Question
 

Okay the threads I've found didn't give me the answer I needed and they got VERY confusing. I was wondering if I were to buy a used TS or JWT ecu from someone with 96 max would it matter if its cali or fed spec? I'm thinking cali spec will give me a cel and a fed spec wont is this true? Also I may do a VI swap in the much later future so would it be worth it to get the TS or JWT? Which one of these would give me the best gains for an automatic?

If you're doing an 00vi swap get a V-AFC II. All motor forum has a thread about the difference. Many guys agreed on the V-AFC II to be better. Research...
