KdFi Pre-Start checks

Before starting we advice you to follow  our quick checklist, quite simple but important tests and checks!

  • Be sure you have established stable communication with the ECU. Wired or wireless. ECU needs external 12V power
  • Calibrate your used sensors under tools in Tunerstudio; MAP,thermistors,TPS,wideband erc
  • If necessary you can test/toggle outputs under Tunderdtudio->test modus; Fuelpump, ignition, injectors, idle & boost valves, spare outputs etc can be tested with a non-running engine.
  • If you feel comfortable in between, to attempt a first start two options are available:

  • Psycho nothing to loose methode:
                Just crank it and see what happens :-D


  • Safe methode

            Verify your base engine settings:

            -Crank it with disconnected fuel pump , and log  you trigger/tooth pattern with the Tunerstudio logger

            -verify trigger -angle, -pattern and -edge. 

            -verify ignition outputs single,wasted,cop coils

            -use the calculator for the base fuel requirements


                                If all those are correct, connect everything again  and start engine!

                                    You should have a running engine;ready to do some tuning.
