Minispeed Trigger Wheel
Turbo Mini Forums

cool, i'll just order the bracket and use my existing EDIS sensor, all i need now is a gold motorbike handle bar :) (nudge nudge:))

hahaha, pm me your address and ill slip one over to you

i also used 3 m6 nyloc nuts and a small washer to space out the bolt holding it in place (ahem a slight bodge!!) so that when tightened it sits square

pm'd cheers matey :)

Trigger wheel and sensor mounting

Each EDIS application requires a different sensor mounting configuration. Use the following table to determine the correct sensor position in relation to the missing tooth and the engine's TDC.

Type Degrees BTDC
EDIS-4 90
EDIS-6 60
EDIS-8 50


With the Engine at TDC, the sensor should be positioned 'N' degrees before the missing tooth. Make sure you take into account the rotation of the engine- clockwise or conterclockwise when determining your sensor mounting.

For example, for an EDIS-4 application, with the engine at TDC, if the missing tooth is aligned with TDC (pointing up, or aligned with the crank pulley key), the sensor should be aligned with the center of the tooth 90 degrees BTDC. If this was a typical clockwise rotating engine, the sensor would be positioned 90 degrees to the left side of the crank sensor (9 o'clock position), when viewed facing the crank.

As long as the relation between the missing tooth and sensor remains constant, you can position the sensor at your convenience. In my case with a toyota 4AG motor, it was easier to mount the sensor on the exhaust side of the block, so I oriented the missing tooth so it pointed down, or opposite, of TDC. The sensor was still mounted 90 degrees BTDC, at the 3 o'clock position when facing the crank.
