[Diy_efi] Injector TESTER

[Steven P. Donegan]

Let me know what the code was trying to accomplish and I'll use my base
PIC circuit (RS-232 comms) to do the same thing - I assume just pulse
width and frequency?

Given my board fab a run of 20 boards (bare) would be <5$/board...

The whole FI tester is interesting in that I get about 3 emails a month from people looking to duplicate this circuit, looking for PCBs and programmed processors. I never really put much thought into making an updated version - I was under the impression that there was not much of a demand for this.  If there is interest then I could spend an afternoon and port the code over to another processor and post an updated version Any of the HC08 or HCS08 processors would be an easy code swap, the timers are identical, just need to be adjusted for changes in bus frequency.
