Velosolex
Posted: 16 Feb 2016, 01:26
Hi there
Somehow I came up with the idea to intsall a ECU on a Velosolex (2 stroke engine). At the beginning the idea was to install a variable ignition timing on the Velosolex. This is not new, there are ready to use units available, but they are very expensive (> € 200). Therefore I was looking for an alternative and I stumbled over the SECU-3 project. With such an ECU the possiblities are much more expandable. Here are a few ideas I would like to share with you, maybe you already have experience with this and you can give me some answers or advice, because I would like to know what is possible before I buy a SECU-3T unit. Basically I am a truck mechanic and know how an engine works, but since I usually work with diesel engines, ignition stuff with the different sensors is new to me....
My new Solex carburetor (on the way) is equiped with an adjustable fuel nozzle like this one http://www.ebay.fr/itm/Gicleur-Variable ... Swqu9U9IOw which is adjustable by just turning it in and out (screw). Would it be possible to get data from sensors like hall sensor, knock sensor and maybe MAP sensor (maybe not possible), and control a stepper motor with the SECU-3T unit, which is connected to the nozzle to adjust the mixture depending on the data the ECU gets from the sensors? Of course I would need make test runs to generate a engine characteristic map for the stepper motor positions on different engine states. If this would be possible, what additional driver would I need?
What is the working voltage of the SECU-3 untis? Would it be possible to run it under 12V?
This is how the velosolex ignition part looks like https://www.google.com/search?q=velosol ... BSAQsAQIHg
I know this sounds crazy to use an ECU for a Velosolex. But we (me and my friends) will participate a 6h race with the Velosolex next summer and I could use this a project as a electro-technic project for a school application...
Thank you in advance for your help...
