Description

Convert your Nissan CAS to a more MegaSquirt-friendly arrangement with our bolt in optical shutter wheel!
This replaces the stock low-resolution Nissan trigger wheel that has four slits with a higher resolution 24-2 wheel crank trigger. Intended for use with MS1, MS2 or MS3.  (MS3 has experimental support for the stock CAS however this will still provide higher resolution ignition timing!) This is intended for use on the following Nissan motors, in alphabetical order.

  • L28ET (1982 to 1983; earlier L28s used a variable reluctor sensor)
  • KA24E (please check before ordering; some KA24Es may have used a 50 mm)
  • VG30E
  • VG30ET

It may also fit other Nissan, Mitsubishi, and Subaru applications. Look for a 54 mm outer diameter with a D-shaped hole in the center. Distributor equipped engines can gain extra resolution and more precise timing, while cars with coil on plug can now use MegaSquirt without having to add a crank trigger. Easy bolt on installation, just take the cover off your CAS or distributor, remove the rotor on a distributor, and undo the big Philips screw in the middle. Once you’ve got that, it just drops in.

What are the benefits of using this trigger wheel over the stock trigger wheel?

  • When used with a MegaSquirt, this trigger wheel allows for more accurate timing (especially while starting) and cylinder identification. If you are having problems with the motor “kicking back” while cranking, this trigger wheel will fix them. It will also permit using sequential injection or distributorless ignition.

Do I absolutely need this trigger wheel when installing MegaSquirt on one of these engines?

  • No. MegaSquirt can use the stock trigger wheel if you are running a distributor ignition and bank to bank fueling.

Can I use this with a non-MegaSquirt ECU?

  • You will need to consult your ECU documentation or technical support to see if this pattern will work with your unit.

Questions & Answers

    I notice on your install is says to use a pull-up resistor with 12 volts. In the msextra manual it says to use 5 volts. Can you clearify which one I should use when wiring for MS2extra? Thanks, Shane

    You can use either one. The sensor can work with several different voltage levels.

  2. What wheel simulator settings are recommended for the Jimstim when testing a ms2v3 built for the dual triggers with this wheel

    DIP switches 4 and 6 on, all others off.
