Error code 54
I have test-ecu and I want to be able to connect it to any car (without removing existing ECU, copy immo code, program my ECU) and fast test why car has problems on idle.... In this model of Carisma are many reasons (3 by-pass valves, EGR, high pressure pump, and ECU) - in specyfic case, after change all parts under hood to parts from 100% OK car, we suspect ECU, and it was good shot. Fortunelly we have almost identical Carisma, for engine swap, so all set key, immo, ECU was easy to connect and check.
