I can feel your frustration..
Keep tinkering your getting there.
Are you planning to use an ECU from another bike to control the injectors etc?
If no, what do you intend to use?
Ride safe, Ted
No, I think trying to make a preexisting solution to fit my particular problem may be more work than just making one from scratch. I would have to reverse engineer an existing system and figure out how to make it behave in my setup. Its possible but I would rather start from scratch and build something where I have complete control of the hardware.
Like everything else I have done so far I will role my own. There are multiple single board processors to choose from. Almost every semiconductor manufacturer has development boards to support their controller chips.
I am looking at a 32 bit micro-controller that is supported by the latest offerings from Arduino. I have made a preliminary design with this.
I am also looking at a controller chip from Texas Instruments. They also offer development kits and support to get it up and running and so i can easily make changes.
Which ever controller I choose it must support C and python programming languages.
As far as the hardware for driving the injectors I am experimenting with a couple of chips from Texas Instruments a TPIC46L02, low-side predrivers, and a TPIC2601 a power DMOS array. I have samples of each. Just looking at the power driver it seems too small to dissipate the heat I think it will generate. But TI specs it to drive up to 6 injectors. The predriver is also tiny it will be a challenge to solder to those tiny little legs.
I haven't given this a lot of attention yet because i want to get a solid mechanical fuel delivery system before I change focus to the electrical hardware.
