Timing Retarding @ high RPM

Mattax said

I think what the latest FBO, Revanator, and Pertronix III try to do is account for the slew. Inb otherwords it adds advance based on rpm to make up for known delay. Or FBO might simply be running the fastest stuff he could reasonably put in there. The Revonator uses patented technique that's been posted a few places. Something to do with triggering based off the previous spark. If there is interest I'll can find it and post which would be much better than my garbeled recollection of something I glanced at.

If I get a chance Sunday I'm going to call Tuner. I'll ask him again about being able to account for slew rate in electronics. I suppose it's possible.

The last time we talked about it (when I bought my distributor machine) we covered several areas and IIRC one was not being able to electronically cover for slew rate. At least not with common CDI type boxes.

In fact, one of his classic stories is about changing over from points to a CDI box and using 3 different timing lights...and the circus act that followed. Classic Tuner story.

I told him to write a book, but he won't. I told him I'll proof it for free. And buy the first 5 copies.
