Timing questions...

[Cheez Wiz]

I hear of chips with various degrees of timing. High, low, etc. The question I have is this: Is there a timing "curve" in the TR's? I.E., is there a such thing as "base" timing, then a progression to the maximum allowed by the chip? Or, does it always have maximum allowed then it backs off timing as warranted by the knock sensor and such? I guess what i'm trying to ask is there a correllation between the TR and a standard style (distributor) ignition?

Yes there is a "timing curve" but what everyone is refering to is the timing @ WOT. This would relate to the basic distributors baseline timing plus mechanical advance but not vacuum advance.

I am sure that others know more about this than I do, But if you have access to DirectScan, it will show you exactly what timing is being run at any time. (I get about 46-50deg at cruise, and 26 deg at WOT) and yes, the knock sensor tells the computer to pull away some of that timing if it senses detonation.

26 at WOT This is a race chip, right???? Sure hope so. Not even hot street chips run that high!
