Howdy, After getting over the feeling that I was borrowing someone else's car to take to the demo derby, I managed to give the old diy/332 website a going over. Well, maybe major remodel would be more accurate. I would like anyone interested to stop by and have a look. WARNING: THERE IS NOW COLOR... LEAVING YOUR MONITOR ON AT NIGHT WHILE TUNED TO THIS WEB SITE MAY PREVENT YOU FROM SLEEPING. Here is a list of what was changed or added: Added some simple logos. Added background colors. Changed some of the navigation. Added global navigation to most of the pages. Created links for FTP access for use from your web browser. Created some new directories for efi332 files. Zipped up and moved everything out of the pile in the incoming directory. Put all of that stuff into the appropriate outgoing directories. Fixed several potential HTML syntax errors. Added several new HTML syntax errors. Made extensive use of tables to give more of a formatted look. (browsers that don't support graphics or tables should still be ok) Here is what I still need to do: Create 00_INDEX files for each of the FTP directories... the file names themselves give a pretty good clues as to what the files are, but I would like to make it a little better, and this would help with "version control" also. Give the generated archive search result pages the same new look as the rest of the pages now have (relax John, you'll get used to it). And above all, fix everything you guys tell me to when you go check it out and find broken stuff. I am not able to test with every browser. I use IE the most cause it is picky and interprets most of the specs very literally... it don't cut you near as much slack as Netscape. I also use an old crusty "doesn't support boo" no-name browser so see what the "Unix World" sees. ;-) Now just a quick reminder then I'm outta your faces; Neither of the mailing lists will support file attachments over 40k in size. To submit files to the FTP site, please put them in the efi332.eng.ohio-state.edu/incoming directory. I haven't looked at the FTP config for permissions there yet, but that directory should accept anonymous uploads... if it doesn't I will fix it. If you would, please .zip or .tar.gz the files first. If you really want to be nice to me, you can include a brief description in a file that is named the same as your uploaded file but with a different extension. That way I can quickly and easily place the file, with description, into the appropriate outgoing directory. Otherwise I have to tear it apart and try and figure out what it is and where it needs to go. One last thing; I would like to extend an open invitation to everyone to feel free to contribute to the site. The content has to remain focused on the efi332 and diy_efi mailing lists. IOW, I am not going to add a bunch of outside links to it, but there is still more that can be done to extend the service these lists provide. If you have an idea, or some HTML you want to add, just mail it to me: allnight@xxx.net I can tell you that sometime in the future, our friend and kind sir, Mr. Bruce Bowling will be adding some useful Java to it (now you have to do it Bruce) and any ideas are welcome. Since some of the navigation has changed, you might want to start at the beginning and update your bookmarks to where ever you used to hangout. http://efi332.eng.ohio-state.edu/ enjoy! - -j- ------------------------------ From: neilaura@xxx.com (Laura & Neil Powell) Date: Sat, 14 Dec 1996 09:27:13 -0800 Subject: Re: oil pumps (not efi) You wrote: > > > >On Fri, 13 Dec 1996, George M.

If you increase the performance of an engine, the engine will generate more waste heat. And as the secondary purpose of the oil is to remove this heat from the internal components, if you increase the volume of oil ciculating you get rid of this heat. Hence the high volume pump. Also if you check most dry-sump setups, they carry a lot more oil than stock for this very reason.

Pin D is where the information comes out, in the form of a lamp level voltage (zero to twelve volts). Your check engine lamp will oscillate with the digital data. If you use a 20K resistor instead of the 10 K resistor, your car runs in "normal mode" instead of the diagnostics mode, but provides the 20 byte data stream anyway. The 3.9 K resistor puts your car in limp-home mode with a backup spark and fuel control map. Give that a try. -- Dan ------------------------------ From: Clint Corbin Date: Sat, 14 Dec 1996 20:46:30 -0700 Subject: Re: oil pumps (not efi) >I have come into this thread about halfway through, so someone may have >already raised this point. >If you increase the performance of an engine, the engine will generate >more waste heat.

It takes a finite amount of time for heat to transfer from on thing to another. The greater the temp difference, the faster the transfer, but it is still a finite about of time. If you get the oil going to fast through the bearing shells, it will not have enough time to pick up the heat it needs to. This can lead to over-heated bearings even though the oil temperature is remaining low. The same thing can happen to the water running through the heads and block, as well as the air flowing through the radiator(the last one is not as big a problem for cars, but water cooled aircraft generally slow the air down with an expansion chamber before it gets to the radiator). To much oil pressure can be a bad thing.

This is the one I was working on right before I down loaded the lightning bolt. Weather's calm so I'll try again. First off, I would not do this unless you want a very quick, easy, extremely cheap, and reliable TB EFI system. I dont know any thing about the 22R. If the CID of the 22R is near 2.5L, and it's not a two plug per cylinder or a 16 valve engine you will not have a problem with the dist. interface. I've used GM HEI modules in Datsun 280Z's for years and I think Peter Fensk was doing it before then. All you need to do, is to connect the 22R pickup coil wires to the GM HEI module. Mount the module on the fire wall or where ever it's convienent. Beware that some engines are not symetrically fired, some GM V6's for example. This will complicate things. I know for a fact that almost any signal will trigger a GM HEI module. I had one connected to a coil on my bench. It even fired with a Ford pick up coil. I've even seen the HEI module inside import modules. If you really want to sleep good at night, hook one up to your 22R and see if it will fire a coil. Let me know how you come out. Check the DIY archives I have talked about this on several occasions.
