Due to the offensive nature and "if you are not doing it my way you are doing it wrong" attitude from the moderator, I will no longer be contributing to this website. I did suspect that it was just a vehicle for Fred to tell the world all about himself and it appears my initial thoughts we...

I managed to get the engine working today in limp home mode. The firmware is up to a stage where I have a 2D map and PIP input and SAW output enabled. I am only using the map in 1D mode at the moment, but the Arduino is suffering terribly with interference as its in the open air near the coil pack. ...

I got the EDIS unit firing over the weekend. The VR sensor was wired incorrectly. I diagnosed the fault, by using the Audio .wav file (From the Heggs website) out of my PC directly into the EDIS unit. This works really well so I was confident it was the VR unit that was the error. I also modified th...

No I meant narrow band as they are very cheap. However the Spartan sensor with the incorporated driver circuits does look quite good for the price and would give me much better resolution for tuning. All fuel injection before 1995 used narrow band sensors, so if I can get my 1934 design beetle up to...

Thank you for the interest in the project. Initially I want to replace the 009 distributor (centrifugal advance only) with an EDIS unit. The advance is to be controlled with an arduino using a lookup table. I then want to add a map sensor and also a narrow band lambda sensor so I can adjust the carb...

As soon as I get anywhere with this I will post all code and details of the build on my website.

First post here..hello. I am developing an engine management system based on an Ardunio processor. I have just set up a board with an EDIS-4 unit and coil pack and cannot seem to get the plugs to fire. My trigger wheel is set up on a lathe and I do seem to be getting a varying voltage from the tacho...
