Question about WOT table in $8D bin

[Bruce Plecan]

> Hi Bruce:  That part of the map is stock 89 man trans 6E calibration.

OK, still would be leary running it on a hot rod SBC.
DIS, v-6, low compression is one thing (ie the GN I have running in mid
50s).
there is a spark limit in the code of 42d, and with the initial you can get
to 48, but your pushing the limits of the distributor.

Interesting test would be to see if the detonation was in a *firing*
cylinder or due to cross firing.   I've run the Gn up to 60d just for grins,
and just wound up having to add TPS for a given MPH.  Also, found that using
the Translator when I was able to run +-2 timing events and let temps
stabilize running Cruise Control.  At 70 MPH can take 5 mins for the heat to
stalize and get a new reading on the *new TPS*.

> I do have hwy fuel set at 15.5:1 at over 62 mph and light load.
> 16.1:1 caused lean misfire.

Dunno how exactly you did that, but you may have not done as much as you
thought you did.  Just moving the commanded AFR to 15.5, or 16 might not be
the *whole* answer.
Would be interesting if someone has a export chip of something hac'd where
we could look at a couple other things
