Speeduino v0.3.x

(4 customer reviews)


SKU: N/A Category:


Current stock is v0.3.7 for the through hole (THT) type in bare board or kit. Blue with white lettering.

There is now an updated version of the 0.3 that is SMD (surface mount devices). It includes some extra stuff over the THT type including a location for a stepper idle module. The latest of the SMD type is version 0.3.B. You can get this option in a kit where only the THT (trough hole) parts need to be installed. There is only the connectors, header pins, and MAP sensor (if ordered) that need to be attached, or you you can order it fully assembled. If you order this board fully assembled there will be a delay to finish the assembly of your unit.

    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?
