Has anyone got a contact number or no of anyway to bypass the Vecta black box.

Sometimes it works & sometimes & doesn't & its getting to be a pain in the arse when im driving. The car cuts out & then suddenly starts again I no its the Vecta as the light goes red soon as the car cuts out & goes green when fires up again. Ive had the dashboard out & when you tap the black box, it cuts the car out & ive checked for breaks in the wires & theres none

HELP REQUIRED PLEASE
