Why ? There's nothing wrong with t2 , and I don't think there is any age difference as ford used it on there promo t230 Ford Focus car . It's cheap and I would rather have that that some old Cossie ecu that's with a pectel board and people are still fitting them to cars now. Unless you want to spend over £2000 now your limited unless it omex or megasquirt.
I would swap to t6 but they go for £1000/£1500 secondhand and new pectel sq6 are more than that just for the ecu alone.
I would like to use life racing but they are expensive so tbh iam not going to gain anything.
