BOSCH D-Jetronic Megasquirt Adapter Options

[shconer]

I have built a prototype board that adapts the factory Bosch D-Jetronic card edge connector in my 1969 Squareback to the DB-37 connector of my Megasquirt 2. Also I retrofitted the factory pressure sensor with a modern sensor inside. With some small modifications to the Megasquirt board to accommodate the external MAP sensor. I have created a plug and play system that works with the factory harness and does not require any further modifications or additions. Alternately you could instead connect the standard Megasquirt onboard MAP sensor with a hose to the manifold and lose the factory appearance. I have done some testing with the prototype board and I am in the final stages of developing the final version. I have designed it to be compatible with early and late type 3 cars as well as all fuel injected 914's. Before I ordered PCBs and components I thought I would see if there is any interest out there for something like this. The final PCB is designed to mount inside of the factory case with room for the Megasquirt. An assembled adapter would cost approximately $80 CAD. This could be a cheaper solution for someone with a malfunctioning D-Jet ECU or a dual carb conversion. The factory idle control system still controls idle. This is a fuel only set up and the factory distributor and ignition is used. Also there is no provision for EGO feedback, it is a open loop system. This adapter works with MS1 or MS2 V3.0/3.52.

Robert, if you are looking to do that and you don't care about looking original you should just use MS without his adapter and run new injectors and LS sensors.

This system is to keep everything stock.

I am in the final phases of my Microsquirt conversion. All LS sensors except for the TPS and Cylinder Head temp sensor. Crank trigger too.

Hi MonkeyBoy,

I'm also in the process of converting my 914 to run on an ECM.
If you are still looking for a TPS setup, I made a few adapter plate for a bosch sensor.
You can search on ebay for: Porsche 914/VW Throttle TPS Adapter/Bracket MegaSquirt ECM

I'm also in the process of making an IAC controller that will accept a PWM signal to control the position.

Regards,

Julien
