I've spent a few hours looking through SOME of the archived references to the ION project. I could not see any significant reference to ION in 1999. In fact most of the interesting information came from 1995! So... 1. I's there still interested in ION? 2. Did anyone decode and post a schematic of the SAAB ION sensor PCB (with the quad comparator)? 3. How can I get hold of SAE950003 & 4? Anyone got the essence of these articles in print (or are the original articles available somewhere via FTP)? I'm really interested in this project but the most I've seen is patent 4,648,367, (and I'm trying to look at some of the others but does http://www.patents.ibm.com/ ever actually work for more than about 10 minutes at a time?). - -- Peter Gargano peter@xxx.au Ph: +61 2 6251 5519 Fax: +61 2 6251 6646 ------------------------------ Date: Fri, 14 May 1999 08:58:56 -0400 From: Dave Hempstead Subject: Re: OBD_II You asked for experiences Wayne MacDonald described what he found with the seeds and the security for the OBD-II codes. This is fascinating, because what I've seen in the OBD-I codes are similar yet different. For OBD-I, it uses the same external scheme for security. You get a seed back from the PCM, then you send it a code based upon that seed. However, the difference is that the code you send back is simpy a one's complement of the seed. Now, I've only seen this on one PCM, but I've also looked at the code inside the OBD-I PCM, and it appears to match. So, it looks like they've implemented a much tougher security method, but kept the same ALDL interface. Wayne, would you care to send me the tables you've uncovered so far. I'm curious what the seed-to-security-code mapping looks like. Also, we've got a guy on the list here reverse engineering the 96 OBD-II PCM code. He should be able to describe the algorithm.

FYI, I'm in the middle of developing a tool which will allow you to dump and then re-program an OBD-I PCM. I'm working with a 95 Camaro PCM. I am curious how many others out there are working on doing this for an OBD-II PCM. Once my program is together, I'll let everyone know, and post it on my web page.

Unless you can talk someone into photocopying them for you, you'll either have to buy them from SAE or copy them yourself. If you're near a university with an engineering department the library will probably have SAE journals. If someone can scan the articles I'll post them on the WWW page. > > I'm really interested in this project but the most I've seen is > patent 4,648,367, (and I'm trying to look at some of the others > but does http://www.patents.ibm.com/ ever actually work for more > than about 10 minutes at a time?). > > -- > Peter Gargano peter@xxx.au > Ph: +61 2 6251 5519 Fax: +61 2 6251 6646 - -- Steve Ravet steve.ravet@xxx.com Advanced Risc Machines, Inc. www.arm.com ------------------------------ Date: Fri, 14 May 1999 11:58:36 -0400 From: "Bruce Plecan" Subject: Re: "ION" information - current status? - ----- Original Message ----- From: Peter Gargano To: Sent: Friday, May 14, 1999 6:01 AM Subject: "ION" information - current status?

I am also about to call the Denver TV station which airs Rosie to inform them that I will be boycotting all products advertised on ANY of their shows that I happen to watch until such time as they stop airing Rosie's show on their station!

US patent 05704321 abstract: ! ! A plasma injector for an internal combustion engine, in one embodiment, ! includes two spaced apart and parallel donut shaped disk electrodes, ! between which a horizontally outward moving plasma is formed via a high ! voltage applied across the electrodes. The present invention is ! characterized by its efficient use of input electrical energy via electronic ! circuitry for driving the plasma injector. An ignition source provides an ! ignition plasma kernel which is several orders of magnitude larger than ! that produced by conventional spark plugs. Use of very lean combustible ! mixtures, in which the dilution of the mixture is achieved by use of exhaust ! gas recirculation, is made possible by the present ignition system. ! Considerable improvement in engine efficiency, and a major reduction in ! NOx exhaust gas pollutants are obtained via the present ignition.
