If you want a hint...some "Logic Gates", resistors, a few Pots, a Diode, an
OpAmp, a few caps, and a few other items have the idle, mid, and WOT lean
problem solved and working. My "Little Black Box" works, it's fully
adjustable for mid and top end, and costs about $25 (that's if you build it
yourself and don't seal it in Epoxy resin.) I'm in the process of
finalizing all of the adjustments (3 pots to adjust) and then will be
running it through some more tests. It's very promising and works like a
charm...even under 9# boost - No Pinging and No Retard box anymore. It
prevents the computer from "learning" the super lean curves that the MAP
sensor is reading. Yup, the MAP shows 30.8" of vacuum under even mild boost
and causes a lean condition. (I've got proof of this as well from two
scanners and a dyno run.)

Hey Bernd,
I'm very interested in your contraption. I run 30lb inj. in my NA 360 and am
still having lean out problems as evidence by the wideband on a dynojet I go
to. I can manipulate fuel press,however, I don't really want to increase it
too much due to volume issues at high pressures;esp when I hit the N2O. i'd
like to try and manipulate pulse width via IAT mods,etc. to try and keep my
fuel pressure at sane levels. I assume your mod will work on NA applications?
Can I get the low down on it?
Thanks,
Tom(11s dak)
