Are you doing hillclimbs or does your commute have large elevation changes in it? Since you are metering strictly with shuttle movement, you have to rig up some means of adjusting that movement with a barometer. If the fixed end of the shuttle can be accessed (its been a long time since I looked at a Lucas mechanical system) perhaps some king of screw adjustment can be added there. If that side is buried inside the fuel distributor, you have to work with the mounting points for the springs in the vacuum unit. That unit could be attached to a moveable piece that was controlled by a stepper motor. This motor could then be controlled to provide mixture control for temperature, barometer, O2 sensor, etc. Modifying the vacuum signal would be tricky since it varies all the time. Perhaps an adjustable bleed, which would only richen it up, could be added. The base setting could be set for high altitude and the bleed increased as altitude decreased.

And what is more, you couldn't *get* a clue if you stripped naked and soaked your pallid hide in clue musk, then did the clue mating dance in a field full of horny clues during the height of clue mating season! I will never get over the embarrassment of belonging to the samespeciesas you. Your life is a monument to stupidity. Try to edit your responses of unnecessary material before attempting to impress us with your insight. The evidence that you are a nincompoop will still be available to readers, but they will be able to access it more rapidly. And what meaning do you expect your delusionally self-important statements of unknowing, inexperienced opinion to have with us? What fantasy do you hold that you would believe that your tiny-fisted tantrums would have more weight than that of a leprous desert rat, spinning rabidly in a circle, waiting for the bite of the snake? On a good day you're a half-wit. You remind me of dogshit. You are deficient in all that lends character. You have the personality of wallpaper. You are a fiend and a coward, and you have bad breath. You are degenerate, noxious and depraved. I feel debased just for knowing you exist. I despise everything about you, and I wish you would go away. I cannot believe how incredibly stupid you are. I mean rock-hard stupid. Dehydrated-rock-hard stupid. Stupid so stupid that it goes way beyond the stupid we know into a whole different dimension of stupid. You are trans-stupid stupid. Meta-stupid. Stupid collapsed on itself so far that even the neutrons have collapsed. Stupid gotten so dense that no intellect can escape. Singularity stupid. Blazing hot mid-day sun on Mercury stupid. You emit more stupid in one second than our entire galaxy emits in a year. Quasar stupid. Your writing has to be a troll. Nothing in our universe can really be this stupid. Perhaps this is some primordial fragment from the original big bang of stupid. Some pure essence of a stupid so uncontaminated by anything else as to be beyond the laws of physics that we know. I'm sorry. I can't go on. This is an epiphany of stupid for me. After this, you may not hear from me again for a while. I don't have enough strength left to deride your ignorant questions and half-baked comments about unimportant trivia, or any of the rest of this drivel. The only thing worse than your logic is your manners. I have snipped away most of your of what you wrote, because, well... it didn't really say anything. Your attempt at creativity was pitiful. Maybe later in life, after you have learned to read, write, spell, and count, you will have more success. True, these are rudimentary skills that many of us normal people take for granted that everyone has an easy time of mastering. But we sometimes forget that there are "challenged" persons in this world who find these things more difficult. If I had known that this was your casethen I would have never read your post. It just wouldn't have been "right". Sort of like parking in a handicap space. I wish you the best of luck in the emotional and social struggles that seem to be placing such a demand on you.

What are the chances that Howell disabled the O2 to "ease" the conversion? Doesn't 4.3L come out to about 258ci? There are a couple of BINs on the web/ftp site (one auto, one standard) for the 4.3L. Compare the price of the chip from Howell to the cost of an eprom burner. :) At least with the OEM BIN you know whatcha got. Also..have you got the VSS hooked up? It made a big difference for me. - -greg ------------------------------ From: Shannen Durphey Date: Thu, 11 Mar 1999 17:07:44 -0500 Subject: Re: Cleanup time I have found one shareware program.

It probably doesn't help the above list member, but it's archive type info...just the same. Enjoy. Here's a little Bosch Lambda chart: Voltage curve of the Lambda sensor at an operating temperature of 600*C. 0.6 0.8 1.0 1.2 1.4 =============v============= 1000 | -------\ .

Most Bosch EGO sensors have a range of .75 - 1.2 Temp has a lot to do w/ switching times on the Bosch EGO. For example, at 350*C the switching times are about .1 second, but at 800*C they're about.05 second. That's a 2:1 change in switching times due to changing temps! Also, the switching characteristics of the EGO needs to be considered too. If you slowly vary the A/F ratio from lean to rich and graph the switching points...then slowly vary the A/F ratio from rich to lean and graph the switching points on the same graph...you'll find that the spline curves do not overlap and are not identical. This phenomenon is known as "hysteresis". You might not really need to know these things, but if you're relying on the EGO to save your pistons from meltdown...it can't hurt. Knowing the characteristics will help troubleshooting and diagnosis...as well as tuning.

I think the OLD chevy power book has some information of the various rear suspension types. I think the mounting of the bar and the bar length makes it all work correctly, just not sure if that still applies to 4 links. Also I think described is the Watts linkage (I think) which you have the center of the pumpkin with a strange piviot device that can also act as a locating device (like a bell crank) with 2 links that center around that. Most good suspension book should have all the geometry and various suspension types. Can get as complex as you want, with lots of ugly math. Try finding the Herb Adams book, I think it is called Chassis Engineering. It was written for the racer not the physics expert. Sandy At 05:54 PM 3/11/99 -0500, you wrote: >Too much coffee today.
