(MUST READ) I have a standing offer from a family member who runs an ISP company to locate a PC at their office for the purpose of hosting the three lists+WWW pages. The only issues would be: 1) aquiring a PC for the list, 2) setting it up, 3) routine maintenance. 1 and 2 probably aren't problems, I'm sure list members could come up with cash or a machine. The only problem with #3 is that there's not a list member located at the machine to take care of problems. Their co-location deal includes some sort of timeout reboot, such that if the machine locks up it'll get rebooted after a period of time. Hopefully other problems can be handled remotely as they are now. They're right on a couple of the big pipes so throughput shouldn't be a problem (diy_efi can go back to non-digest!).

So, the Red should be the signal wire. Um... so you're saying that there is a sensor ground, a shield and a signal wire? What sort of sensor is this? Is it a hall effect sensor (which definatly require a power supply) or something I am not familiar with, like a reluctor? I've just hooked it up to my osciliscope. Between the black wire and the red wire I get quite a good signal (of the order of 1 volt p-p) by waving bits of metal in front of the sensor. There doesn't appear to be a connection between the braided sheild and anything else. Can someone explain how this sensor works? Is it just a coil of wire with a magnet through it, and when metal comes near it disturbs the field changing the flux through the coil and therefore inducing a voltage? Is this the reluctor sensor that I've heard about? - -- Tom Parker - parkert@xxx.nz - http://www.geocities.com/MotorCity/Track/8381/ ------------------------------ Date: Wed, 10 Nov 1999 16:46:23 -0800 From: "Todd....!!" Subject: Re: [admin] What next.... (MUST READ) Two quicky idears pop to mind! Since you have more than 1,500 subscribers, #1: Request each subscriber(each of us) to send in $2 per YEAR in order to maintain the list...? INSTANT $3,000/yr.... OR #2: Get a sponsor who can stick his ads at the top of each e-mail! I think a teenee tiny ad at the top of each e-mail wouldn't hurt anyone... And if it comes down to it... it would be an almost unnoticeable change to the list.... You YOURSELF could even offer sponsorship (i.e. sell advertising) to various auto parts dealers and like suppliers for a tiny contribution in return! Whatchatink? Just for example, my Dad has a body shop, brother in law owns and runs the auto parts store in his town, cousin in law works at a big car dealer right outside of WACO, TX, etc..... I'm SURE others on this list have the same kinda of friends, family, acquantances and the like.... that may want to sponsor somethin such as this list! Just a couple a thoughts! Got a 10% raise today without even askin for it! COOL? Not much but at least it's SOMETHIN! Keep up the GREAT work all! LATER!

If you build ECU6, use the Intel 80C51GB (I think I have a spare if you need one). If you want to use another CPU, then go with ECU7. > The look up table for the map/tps/coolant/O2, can they be trimmed > down to remove the TPS and coolant but add in a MAF portion? They don't yet have TPS, and Yes, the coolant temperature protion cal be removed. I'm sure you could add MAF, but this would take the place of the MAP input (and require appropriate modification to the tables). > The jumpers in the circuits are to be used for what purpose?not too sure > about that too.. They are not used - they are just for future expansion. > There are two injector drives in the circuit, are they in sequential > or batch mode? I have the injectors firing in batch mode, but this is controlled by software, so you could program them to work in sequential mode. and the variables in the BASIC program called LSB > MSB are for > calculating what? They are the Most Significan Byte and Least Significan Byte of the duration for which the injectors are to remain on for. They are values converted from miliseconds by the BASIC program. They feed the appropriate input to the EFI02 ASM routine. > > By the way, do you have any more EFI ECU6 boards I could buy? Yes, I have one left. Let me know if you want it.

Im getting ready to drop a tpi engine in my car and i need a prom. Im going to run a 350 flat top with 24# injectors, Tpis big mouth intake, slp runners, lt4 hot cam, 1.6 roller rockers, and sportsman II heads. I have the 165 computer. I need a prom with no cold stat injector with a mass air. So i guess i have to run a 89 prom right? Will a stock 89 prom work or will i have problems with vats? Also im eliminating the egr valve. thanks Mike ------------------------------ Date: Wed, 10 Nov 1999 21:24:56 -0500 From: "David A. Cooley" Subject: RE: [admin] What next.... (MUST READ) John, As far as the list traffic, have you checked into onelist.com? It's a free mail list hosting service. I'm on several lists thru there and get quite a heavy load. As far as web space, how much disk space etc is needed to host the web sites? Fortunecity.com gives you 20MB free, Geocities/yahoo give you 10MB free, XOOM gives unlimited, but their servers are really slow.

(MUST READ) I sent a reply to diy_efi but it looks like most of the discussion is on the other lists. I'll summarize, if we can scrounge a PC and get it configured I can get a free co-location at an ISP that a family member runs. Only problem is not having a list member "on the spot" to kick it when necessary, but I think that's a minor problem. They're on one or two big pipes, so throughput isn't a problem (diy_Efi gets OUT of digest mode!). - --steve Orin Eman wrote: > > > As far as web space, how much disk space etc is needed to host the web sites? > > Fortunecity.com gives you 20MB free, Geocities/yahoo give you 10MB free, > > Neither would be big enough due to the mailing list archives... > > My local copy of the web site is 130 MB and the ftp site is another 140! > (This was as of the end of August.) > > Orin. - -- Steve Ravet steve.ravet@xxx.com Advanced Risc Machines, Inc. www.arm.com ------------------------------ Date: Wed, 10 Nov 1999 20:38:44 -0800 From: Mark Romans Subject: Accell DFI Hello all: Kind of interesting. I went to SEMA show and spoke with an engineer at the accell booth. Asked him about DFI, he wanted to show me the latest version. WHOA!! Talk about "If I had a wish list!!" The basic computer has all the switches in the software, you can add modules depending on what you want to do. Software switchable, plug in your choice of wide band, 1-wire or heated o2 sensor. It will run in closed loop just like the Speed-Pro at WOT. Up to 16 injectors, staged. Distributorless ign. Up to 8 cyls. Plug in your injector size, and hook up the nitrous, plug in the nozzle size, pressure and bottle temp and the ecm adjusts the pw to work with up to 3 stages of nitrous. Normal, and 1-3 bar map sensor, set the software. More I can't remember! It was Windoz, 95,98 & NT friendly!

My server is a dial-up server with a dedicated IP address, utilizing two 56K modems in parallel, using somethign called multilink, which in a nutshell, means the two modems appear on the internet as one modem, sharing an IP address, combining the bandwith for a pitiful 112K max baud. I currently use NT for my firewall, my exchange server, my web and ftp, and my linux majordomo box quietly hides behind the exchange server, using exchange as a relay (from the inside only), so it doesn't need DNS information. It assumes the exchange box can figure it out. Anyway, I did some preliminary testing of performance this evening, and found that Linux, with its magical ability to have the OS/programs talk directly to the hardware, can offer 30% gain in ability to use bandwith over NT 4.0 with any service pack release. Exact hardware. So if Orin & Steve run out of options, or cannot find a service that will host the list(s) for a reasonable amount of money, maybe we can do it here at Xephic. Hardware is clearly not the problem. Even though most of the boxes are not new spiffy pentiums 400's (they are actually much older clunkers), I do have tons of disk space available, have a tape library system for proper backups, several CDROM towers, UPS power, and "data center" like floor mounted racks mounted in an airconditioned basement that could be used as necessary. I can even configure majordomo, however what kills me is the ipchains/ipfwadm firewalling, sendmail, dns, and other configurations, which would be necessary for "My" stuff to remain in place. I can do this all in NT exchange/proxy with my eyes closed, but not in Linux, at least not in a very short period of time. I can offer the hardware, hosting, storage space, but I'd need a few hands helping me set all this stuff up properly, and reliably.
