    Description

    Ever wonder how to adjust the timing on your 1999-2005 Mazda Miata? Surprisingly you cannot adjust the factory timing by clocking a cam sensor like previous Miata's, until now! By simply replacing the factory timing encoder (timing) wheel that sits behind your crankshaft pulley with our specially designed slotted wheel, you can advance or retard your factory timing to meet your desired tuning needs.

    The 1999-2005 Mazda Miata engines based their ignition timing by way of a crankshaft position sensor. This sensor is simply an electromagnet proximity sensor that senses a passing "trigger", which physically are the four small tips you'll see on your stock trigger (timing) wheel. By allowing the timing wheel to be "clocked" (rotated within it's mounting location), we can now trick the ECU by triggering the crank sensor just a touch earlier (or later to delay it), which in turn will fire the ignition earlier, and consequently advance (or retard) your timing. Very complex in theory, yet very simply done! In the end this wheel will work perfectly in allowing you to advance your ignition timing to achieve better performance, or retard your timing to accommodate a turbocharger. How much performance you ask? Check out our dyno results below!
