1) Set the TPS voltage very low – something like 0.9v. This ensures you can run the engine and move the idle screw about without the interference of the ECU thinking it needs to add fuel.
2) Balance the throttle bodies and set the idle speed to 950rpm. Useful if you have easimap because it will report the exact number rather than the rough approximation from your tacho needle. With the engine set like this you should see ~4.5 kg/hour on your synchrometer into each cylinder.
3) Set the TPS voltage to 1.04v
4) Double check you’ve still got 950rpm / 4.5kg/hour
