you can run Sequential or Semi-Sequential with the same wiring harness. All you need to do is switch the plugs of the 3rd and 4th cylinders. In a 4 cyl
At the time of this vid Josh's policy was NO drive by wire, because he thought it could cause an out of control situation, but I don't know about now. I think other people may have written code, so you'll have to ask on the forum.
So speeduino will support 2 sets of injectors??, per cyclinder?? ex adding water / methanol upon boost over say 9lbs?/?? or where ever i choose?? WOW.... what does Speeduino lack vs say megasquirt or HPtuners? what are the max channels supported? can you piggyback multiple speeduinos for tons of sensors, ex transmission brake/shift points, wideband02, valve timing, EGR, AFR, turbo boost, wastegate etc etc????
So long as they are high-Z INJ or low-Z with resistors. It's basically the current capacity of the traces on the PCB that is the limiting factor. I'm not a high level DIY EFI user, so you will have to research the Wiki.
Is there anyway for one to learn more about constructing a mechanical simulator? Maybe a website or forum? Or your contact info? I’m really enjoying your videos.
It's not that hard if you're mechanically minded, but it's 2 shafts connected together. One runs at the engine rpm you want to test(crank), and the other runs at half the rpm(cam), ie, it's sprocket has double the number of teeth. It's mainly DIY CNC stuff from ebay, ie, sprockets, shafts, bearings, some 3D printed disks with slots, and a motor and power supply - a motor with the right rpm is the hardest to find. There should be a latter vid showing it from the top somewhere here.
@@SidneyCritic I saw another video post you mentioned the stepper motor was from a printer if I remember correctly. So you just thought up the simulator on your own never seeing one before? Thanks for the idea and response.
@@spencert4840 It's not a stepper, it's just a simple DC brushed motor with an adjustable power supply varying the rpm. I work on car engines and it was simple logic. The cam has to run on a 720º cycle because it's a 4 stroke, ie, it has to open the valves once for 2 crank revolutions., hence half speed. You can now see any timing mark on a cam will find any crank degree on that 2 rpm 4 stroke cycle, hence it can run exact timing sequential.
Your videos are helping me, thanks for posting!
Thank you so much for these videos.

Useful demo , thanks
Thank you for this info
Mostra como fazer no stm32f407?
Where do you adjust injector flow rate for a given MAP reading?
Is the Speeduino good for communicating with a drive by wire system such as Polysyncc/oscc?

The diagram at the beginning of your video, where can I find that?
