Well, Texa produce their own diagnostic equipment, and we at the UK software office (it's an Italian company), are responsible for making individual software systems for Ford JLR cars. So yeah, basically reads all parameters and does any settings and adjustment routines that may be on the ECU. Interesting stuff tbh. Just finished doing nearly all of the main ECU's for the new Transit Custom and Connect, so they should be winging their way onto the next Texa IDC4 release!
