    ECU wiring should be done properly, previously it was running with direct current to distributor for spark which is good enough fr CNG. Now ECU should get all required inputs and ignition will be controlled by ECU itself if u want to run it on petrol.
    Keep a cool head and wear seatbelts!

    Try to source an original ECU from shershah, olx or you can start a WTB thread here on PW. I think I saw an ECU for your car on OLX once. Also try contacting PWheelers from Peshawar, Lahore or Islamabad, they have more resources for sourcing out the said ECU.

    ask the previous owner for the ecu if not present. its a mk1 engine the ecu code is ep-001. parts would b very hard to find as this model was discontinued in 88. very few engines which one finds in scrap market are either mk2 or mk3 which usually comes without ecu. although all g13b dohc look the same from outside but are very different from inside and have different ecu's and sensors. pm me for any details you require.
