    Default Speeduino - has anyone considered this?

    Hello

    I was looking into low cost programmable ECUs and came across this project:

    https://speeduino.com/

    Has anyone considered this?

    Possibly about half the cost of MegaSquirt.

    Can utilise TunerStudio for tuning/“selftune”


    Cheers,

    Chris

    I have seen it, but not looked into the detail of it. Looks like an interesting project.

    That sounds encouraging then - are there any obvious dramas you’ve come across? It would be going into a 306 XSI (xu10j4r) with bigger injectors and maybe gti6 inlet/exhaust manifolds - if I can get them...

    Cheers,

    Chris

    No should do all that, lots of choices though in terms of what board etc, I would buy and assembled one if not confident. Will be some time for me but happy to assist / learn. O2 sensor will be an issue for you to decide, wide or narrow band. It handles both.

    I’d be happy to assemble but may go down the assembled/tested path to save a bit of time. Ultimately want a swappable ECU so will rat the Bosch ECU connector from somewhere.

    Fire up protel an make your own Arduino shields. And connection boards. Then you can customise the pcbs to suit the donor connector from the bosch.

    Doubtless you are fully qualified and capable of running protel (or your chosen package)

    And a project that is plug replacement to existing wiring is likely to have much appeal on Af.

    Thinking just that although using Eagle on linux and a host bosch to tidy it right up. ie make it insertable into bosch case, wire internally, then plug and play

    Not sure how street legal it would be if it's for a street car. If it's in a modern ADR engine you'll need to meet emissions standards which means dyno time. In NSW you can't have an unlocked ECU, so put a sticker over the programming port so it looks locked.

    Perhaps that is why the idea of placing the aftermarket unit in an original enclosure has been suggested?

    "What the eye doesn't see the heart doesn't grieve over" is the quotation I think. But then I got Thin Arthur wrong! At my level, I'm excited to find an inlet manifold that takes a 32DIR Weber instead of a 32PBIT Solex. But I do enjoy following these threads.

    I'd suggest there are many variations on a similar theme as to the phraseology of this old time adage.

    I'll let you find the source from which my chosen version was checked.

    Anyway, out of sight out of mind.

    Another variant is Watkins' first legal principle

    "Nothing's illegal until you're caught" V 2.0 adds " and there is an effective sanction"

    Suspect that a few of us use this principle - one of the many advantages of driving old cars, young folk these days don't know what they should've looked like

    In a similar vein, I had to get a laugh, from a Policeman , in one these TV highway Patrol series.

    Inspecting the rear wheels of an Audi A4, being driven most antisocially, in order to conclude the driver had been doing "burnouts".

    Built one for my race bike for ignition timing only. Long term project tho. (1972 Imola Guzzi 750 look-alike for Period 4)

    in the bikes, for my period, must use round slide carbies, & visible mods must be hidden (so I can run an ECU, but the wiring to the crankcase must be not visible). Should get 100 Hp from 750cc....

    I am over halfway done in completing my Speeduino design for the Jetronic/Motronic system. My plan is to have it plug and play with the existing loom (with some minor wiring mods for req'd sensors), and house it in the same case as the Bosch ECU.

    The circuit has been transposed from the developer's fritzing schematics into Altium.

    Speeduino - has anyone considered this?-speeduino-schem.jpg

    Also completed drawing the board to exact dimensions, including placement of the 25pin Bosch connector.

    Unfortunately I have not had the time to continue lately as I have other car stuff to attend to. However I have created all the PCB libraries for every component required so it is ready to basically drag and drop.

    I should really start a thread on the design so we can make it a community effort.
