I just got my Bel STi and it is a 2608 with A4M9, before I received it, I got the dealer who sold it to me to send it to Bel to have it flashed for the Ramp-Up fix. I have tested the Ramp-Up and it seems gradual like it should be so that's good.
From what I read on these forums, I should be looking for an A6M9 or A7M9 to avoid the 33.8 KA problem.
Should I be worried about having an A4M9? I have read on these forums that Toronto police use 33.8 KA so this would directly affect me.
