    Turbonator SMEC using high-impedance injectors

    This is one of those stupid long-term issues that doesn't really affect much, but when things are good, you're reminded that it's still there. I've got a persistent code 26 from using SRT-4 injectors (which are high-impedance) on a SMEC. I've got over 45k fun miles that prove the injectors work beautifully. As a bonus, the transistors aren't working as hard to fire them. But that pesky light......

    Is there any option in the Turbonator code base to get rid of that, even if it's by some roundabout method of trickery?

    It's not trickery, but it's not a well-known thing to do. Masking error codes in the later software is different than it was in he LM and T2 SMEC.

    You need to go to 0-Setup-->Cal Configuration and set the first 3 'ErrorBitsMask#' to 0x16, 0x17, 0x18. There are actually 3 tests for the injector current. These codes will stop those 3 tests from setting an error code.

    If ErrorBitsMask1 is already set (to something other than 0x00), then go to the first mask byte that is 0x00 and start there. The last mask MUST be 0x00.
