Speeduino v0.3.x

(4 customer reviews)


SKU: N/A Category:


Current stock is v0.3.7 or later. Blue with white.

I get a lot of questions about the backorder status of the assembled version of this board. I don’t have a lot of time to assemble these units, but there is not a perfect alternative to them (though a 0.4.4, when they are in stock, with an ST04 is close). So because I don’t want to leave you screw terminal guys in the cold, I assemble them after all my other Speeduino related tasks are finished. How long is that going to take? Usually about two weeks.

    I have ordered a couple of these V0.3 boards (assembled) and used one to complete a fuel only conversation to replace the “Bosch D-Jetronic” I had. These are the bomb and I am telling my friends with Bosch D (Volvo, Saab, Mercedes, Porsche/VW, Renault) to upgrade. Thank you WMarkel for all you do for this community!

    Got my 1990 geo tracker alive again.
    The V3 speeduino fits nicely in the original ECU box. I simply cut the ECU pcb and used the original connectors from it.

    Fuel only for now.
    Installed a crank sensor on the front pulley (Made the wheel from a motorcycle sprocket) welded it to the pulley.
    I could not get a clean signal with a VR conditioner.
    Got a lamba O2 installed.
    All is working well… Thanks for a fast service

    I ordered this about a month ago and absolutely love it. The customer service was great and the order shipped out immediately. Unfortunately COVID slowed all packages down during shipping but that wasn’t any fault of theirs. The parts all came labeled, proper quantity, and functional. I was able to assemble it and currently have it running an NA miata without any issues (other than ones caused by me). Great company to do business with and a great product.

    Hi, what case do we use with this ecu, slim or normal Hammond case?
