Mode 6 went away Rusty. The EC2 now has a turbo boost retard built in that linearly retards timing between 32 to 60" Hg. Nominal timing is 13 deg BTDC by the time it reaches 60" MAP. This is to avoid detonation.

Tracy (wants to go to Mojave too) Don't we all.... If only I had Ed's free time :-)

OK, so what was I doing when I adjusted on mode 6 ? Nothing? 'Cause I'll admit I don't remember much? I have the new chips that were sent with the EM2... I assume that these have the new function?

        Ken Welter told me that it works for him, however I haven't heard back from him. I don't know if there is an easy way to confirm this. Any volunteers?

The other thing we have to ask is what ignition controller is Ken using? If he's not using Tracy's then all bets are off. Mazda times these plugs differently, but I'm pretty sure that Tracy times them the same. Turning off the trailing plugs with an EC-2 might not do a thing, or it might work better. I just don't know.

Tracy already has a timing advance feature (mode 6), that can be used as a timing retard of 4 degrees at whatever MAP setting you want. I'm not sure that's enough change though.   If there's going to be a new feature, why not make something more along the lines of a significant timing retard that happens at a set MAP.  This would stop detonation, as well as notify you via reduced power that you had crossed the line.

Cheers,

Rusty (wish I could go to Mojave to watch the space flight)
