36-1Triggerwheel in place... (Rebuilt in later post)

Mounted my adapter on the pulley. As you can see it's put above the pulley since I didn't want to loosen anything and then fixated with 4 screws into the pulley.


This is how it looks...



Attatched the trigger wheel to the adapter and placed the 6'th toot after the missing one right infront of the sensor.

After a nervous wait my fuelrail finally arrived...

After a nervous wait my custom made fuelrail arrived, had some difficulties to measure the exact distance between the injectors on the top and was afraid that the rail wouldn't fit... but it was a perfect match...

FYI... the mesurement for a Mercedes M110 fuel injector distance in mm
   
I----93,5----I----93,5----I----93,5----I----93,5----I----93,5----I
I------------------------------ 467.5 mm --------------------------I

The injectors fits perfect into the fuelrail

Upgrading the ignition

Since I'm still waiting for some parts for the fuel system swap I decided to start replacing the ignition. I will mount a trigger wheel on the crancshaft pulley which will be used to trigger both the fuel-injectors and the ignition. Hopefully I will get my adapter for the trigger wheel soon so that I can start mounting it on the car.

The Megasquirt ECU will controll the ignition by using 3 "coil driver transistors" wich fire 2 spark-plugs at time (Wasted Spark) via a 6 Coil Pack. The "coil driver transistors" are mounted at the Relay Board's aluminium chassi and the the signals are taken from the circut board.

The Coil Pack costs about 450kr (75$) and the transistors about 50kr (8.5$) each. The Coil Pack can probably be found much cheaper at nearest junkyard...

Very simple function, the coil has a permanent 12+ connected to one side and the other side of the coil are grounded via the "coil driver transistor" when it's time to fire.This will replace the distributor, old transistorized ignition box and coil.

This is the ignition table I will start with and then calibrate it while driving...
