You have said that a 90 degree bend is a tool the filter designer can use to cause a separation. Look inside the part which is under scrutiny. All engines need good air filtration, the more the better and I agree with you. The Pacific is an ocean while the Gibson is a desert. How do Mercury outboards filter their air? http://www.turbofast.com.au/crazy.html Think you have to be crazy to get in one. The alternator? Knowing the lay out and other built in safety systems, I can most assuredly state :- "Ray's engines came in 1st (Aust), 2nd (UK) in the World Final in Spain. A third engine also won one other major event at these most recent World Championships. The kind of danger you have in mind does not cause a problem in this formula. I think I would be more worried about the danger posed by a LOW FLYING DUCK or being smashed to pieces or drowning or both. These would be high on my order for concern. Thanks for the dialog. I will not be building my Lucas boat FI system. If some one would pay me I would build both. It would however be committing the sin of omission to accept such a job without first predicting the out come. Ken has told to keep out of his Outlook Express 5 and dumped my little email folder that I was accumulating, which I stuck on his desktop. I'm on Linux. With the $50,000 we will save this year by not giving it to Bill gates, I might be able to dump the Commodore and buy that BMW you mentioned.

Hmmm, some new folks coming in since the rebirthing of the list by our intrepid administrators. So maybe time for an EGOR update, eh? We're getting VERY close to being able to officially announce both the module AND our first meter (a marketing decision was made some time back to wait on offering the module, until the meter was also ready). You wouldn't believe the number of logistics/parts/packaging hurdles we've had to hop over; but I'll spare y'all the pickyune details. Suffice it to say, whenever you need to package something to look pro, there gonna be dragons there. Wait till you see the meter; pretty snarky, IMHO. For those unfamiliar, "EGOR-the-module" is an interface for a current-pump-style NTK-Honda 5-wire wideband sensor, basically it's a black-box with pins, around which you'll be able to build a WOT/wideband-O2 engine manager; and "EGOR-the-meter" is a hand-held precision AFR meter with large digital and bar-graph display (and an analog out for logging, of course), useful for tuning/cal work. I can't tell you much more until the official announcement or it'll be the firing squad for both of us, but I can say both the module and meter are indeed going to be VERY affordable. And I mean VERY. This should bring precision wideband O2 sensing within the reach of every proformance afficianado, even those on a tight budget, without sacrificing accuracy or function one bit. Believe me, we're as anxious to get the roll-out underway as those who've been waiting patiently. So just stay tuned to the list, and we'll have an announcement and a web-page you can go to and have a look, shortly. Ole EGOR's comin, and we trust he'll be worth the wait. What hump?, Gar P.S. ION's in the wings, right behind old bug-eyes, and since she is only in module form anyway, we shant keep you waiting so agonizingly long to get your hands on her. - ---------------------------------------------------------------------------- To unsubscribe from diy_efi, send "unsubscribe diy_efi" (without the quotes) in the body of a message (not the subject) to majordomo@xxx.org ------------------------------ Date: Wed, 22 Mar 2000 13:18:18 -0700 From: "Chad" Subject: Re: O2 sensor question I don't know the exact engine, but it's on the 1999 model.

The "fattest" I guess would be StarOffice which is a free "replacement" for the Micro$not bundle-o-bugs. There are quite a number of lighter options for email clients which you have similar capabilities. I stay in the "ChUI world" for email; much less likely to import virii, worms, etc. so elm does the job.
