Evening, Have a discovery 2002 V8 converted to LPG and have been having problems with cyclinders 5 & 8 for the third time on both LPG and petrol. Mechanic and self have come to conclusion that likely related to ECU because happened once before conversion to LPG. Need to know part number of ECU to find good used one second hand because new one too expensive. Would also be grateful for any other useful information for me to consider with regard to the problem. THANKS!
