Tuning with the DIY-WBs

[Bruce]

Well,
life just got easy.
Almost too easy.

I have a couple of Bruce R's LED display boards.
This is truely getting to the stage of being unfair.

In summary, they use 4, 10 element LEDs.  So you have 20 green and 20 red.
As you go lean from Stoich the red ones illuminate.  Richer then stoich on
the greens go on.  They are in bargraph mode, and in columns.  So, at a
glance, you see 2 reds, OK you at a little leaner then 15:1.  Couple Greens,
your at 13:1.  No lights on, your at stoich.

Seeing lean transistions, are just as clear as day.  Tip in stuff can be
cured in 2-3 tries, since you can so accurately see the leaness.

WOT,
The unit can be out of your line of sight, and you can *guestimate* where
you're running.

They are responsive enough that if you run two of them you can see the
latency in the exhuast system.

I'd still use some datalogging for optimising your system, but this makes
getting the drivibility stuff a piece of cake.

Amazingggggggg,
Bruce
