Arduino ECU By Brenamanf

I was sent a link to this website by the author, who appears to have created an Arduino ECU for spark control. Although the details are a little sparse, It appears that he has developed a lot of the required hardware himself. It looks like the main controller is an Arduino Nano and utilises Manifold Absolute Pressure (MAP) and a knock sensor to determine the ignition timing on a Peugeot 205 Tu9 45Ch. It would appear that the ECU has been developed over a number of revisions and has been in operation for over a year.

      I thought your blog was very interesting, some good work!

      The in-cylinder pressure sensor is a device from Kistler. That one is a custom built spark plug, which makes it very expensive ~£6000, but there are cheaper Kistler options – still ~ £1600 though, and require drilling into the head. There may also be other people making In Cylinder Pressure sensors.
