From the initial descriptions I found, it was a solenoid, pulsed rapidly to shuttle the valve open and closed to meter air. Now I've found some descriptions that make it sounds like it's fed a pulsewidth modulated signal that varies the voltage, pulling the solenoid only partly open as needed to meter air. Using it like a shuttle valve would be easier in software; using it pwm would be harder since you could never know exactly how much air the valve was passing, since there would be no feedback from the solenoid's position. ------------------------------ From: "Randy" Date: Thu, 11 Feb 1999 09:17:13 -0400 Subject: Re: Going to unsub Check out the FAQ at www.f-body.org I'm not sure what tips you're looking for but there's a lot of stuff there.

I think most of the additional expense of a mechanic's gauge is the fitting attachment for the schrader valve. I bought a mechanical liquid filled gauge for about $40 that threads into the port that contains the schrader valve (you have to unscrew the valve). It's very accurate, at least for my tuning purposes (within 1psi). I assume the schrader valve attachment has to be pretty failsafe, thus the added expense. Just my $.02. BTW, I don't know if my previous post got through, but Jegs lists a digital electric fuel pressure gauge with sender for about $80. It's a 20-100psi unit.

Set the frequency high enough to not pulsate the thing. 200 Hz should be fine. Basically you want to increase the pulse width when you want it to speed up and decrease the PW when you want it to slow down. I don't know which way it operates - if it bypasses more air when alot of PW is present or when none is present so you may have to reverse the PW correction.

In short, everybody who's not GM or almost that big, sit down. Essentially an OEM comes to them and pays $$$ to have the chip put into a custom housing, something convenient for the OE, say that bolts right where they want it to. Since the OE paid for the tooling, Moto won't sell you or me any of those units, and, at least for the IPS, there is no "generic" version. (There were other devices mentioned in that web site but the story is similar for most or all of them.) Not to say you can't get 1 or 2 from your fave Moto brownnose, if you have one, but it's unwise to design in on that basis. I asked about the MPX (air) pressure sensors, they're made by another division and are not really related. Also there was apparently quite a bit of R&D to make the units work in contact with hot pressurized fuel or oil, just a word to the wiser DIY'ers who might be having what we call Thoughts. ;) The good news is, at least the IPS is apparently used in the '99 Mustang, some '99 Escorts, and perhaps some other Ford apps. So you should be able to get one from yer friendly Ford parts counter, if you don't mind that it only fits (conveniently) onto a certain fuel rail and (perhaps) intake manifold. The situation is similar with some or all of the other devices mentioned, i.e. they're used in various high volume domestic OE apps, so if you can find out who uses one where, you can buy one. So that's what I know 'bout those. ... The better news, for me, is the variety of fuel-rated pressure sensors that people have posted about in the past few days. That's all I needed, really. I can already measure MAP, and I can subtract - so PWM fuel pressure system, here I come!

When I back off the accelerator and put in the clutch to shift, the engine RPM stays the about the same 1-2 sec before dropping, and it doesn't seem to drop at a very predictable rate. Now a while back I drove somebody else's FI manual transmission car (but for the life of me I can't remember what it was) and it seemed about the same. This condition is very annoying to me because it makes it difficult to achieve a smooth shift by letting the clutch out as engine RPM matches with the next gear. Any clues on what causes it and what I could do to avoid it when I build my next project? I suspect it has something to do with the engine management being more built for an automatic, where such a condition would not be noticable, but what do I know.

I recall a statement made some years ago about not being able to get a Vette in CA with a 4 speed because of a momentary increase in HC or CO during the upshifts. carburated cars used a dashpot or dampener to slow down the throttle return for this reason. just a thought, but it might explain it.

I've never seen such a pump. Liquid N2 is delivered in a presurized container (like propane). We just open a valve and pour it out of the hose into the container we need it in. It lasts for a surprisingly long time before evaporating. What's your application?

UPAC=union of pure and applied chemists Toluene for example is methyl benzene, geez, I hope I'm remembering that right :) Or a chemical formula, might help. toluene is C7H9 at least it will tell me if there is any oxygens or nitrogens in it for example. Problem is, if it's significantly different it's octane rating will be different as well. Flat aromatics like benzene, toluene and phenols aren't the greatest octane boosters. They tend to be the culprits when we talk about a 'gummed' up carb. or injectors. Is there something about methyl t-butylether (MTBE) that you don't like?
