    Greetings from Southampton

    You have been busy, busy, busy! Well done, I think I might be too low-tech for your modelling?

    I am looking for an Arduino based solution to control the ignition advance (not any injection) on a Rover A Series carburettored engine, with a means of modifying the ignition advance curve with respect to the manifold vacuum.

    I also have a high output Lumenition ignition system (optical trigger). I have a lambda sensor as an indication of fuelling, though it has been rollingroaded. I will also have a TPS input from the 1 3/4″ SU carb. I have the vaccum measurement sorted out along with the initial ignition versus rpm profile tabulated from the non-vacuum distributor. The lambda reading is as a voltage 0-5v (2.5v for lambda=1)

    Are you aware of such an Arduino animal to control the ignition advance based on rpm and manifold vacuum?

    I understand what should be being measured and responded to BUT it would be good to hit the ground running .

    Many thanks

      Hi John,

      Sounds like a very interesting project! If you take a look at some of my other posts, you’ll see I also had a classic Mini – I was intending on developing an ECU for it. Unfortunately I didn’t get that far before crashing it! I would certainly suggest taking a look at the Speeduino project which is an awesome Arduino based engine management system. I don’t see any reason why you wouldn’t be able to use just the ignition control part of it, or just use it as a starting point for your project!.
