    New ignition ECU

    No....not starting this yet (I'm burnt out). But was just thinking. Set your base ignition timing to 16 or 20 degrees and the ignition ECU would add a delay (RPM dependant) to bring the timing back to standard 12 degrees. Then have switch to select more advance with an adjustable setting from 12 to 20 degrees.

    That way I could switch the more advance when I select my richer POWER mode.

    It was described in the old forum.

    I run a wideband (Innovate LC-1) in my car. It has two analog outputs which I can program to two different AFRs. So I can switch which analog output I feed into the lambda ECU. One is set to the standard 14.7 AFR (ECONOMY). The other is set to 13.2 AFR (POWER).
