    Great guide on ECU / Fuel injection here:

    Note: This procedure should be similar on any engines using an flap for measuring the air flow. Those who use Lucas ECU box and an Hot Wire to monitor air flow are slightly different. We used this procedure successfully on many different cars. [highlight]But it's at your risk. And you may well damage a component beyond repair if you screw it up.[/highlight]
