Someone have information about the ODEGA system (On-board Diagnostic Exhoust Gas Analyzer). I readed about a proyect and Ford, GM and Chrysler want to put a small gas analyzer to comply with poullutant norms. Thanks.

If so all use for OBDII, a 2nd o2 sensor after the cat to measure cat efficiency and log error if bad. If not , there are in development, solid state gas sensors that will measure multiple gases. Dr John Gland @ UM is a major developer in that area. frank parker > > ------------------------------ From: Troy Bryant Date: Sun, 5 May 1996 23:19:30 -0500 Subject: Re: L-jetronic info I currently have a 85 SVO Mustang, which is modified a great deal, the problem I am now facing is the air volume meter, which is a Bosch unit. Has anyone ever converted one of these engines to run a mass airmeter which would increase the air flow to the engine. Other people have done it in the past, but does anyone have any ideas or inforamtion. >Troy At 09:58 AM 5/3/96 +0200, you wrote: >Werner, > >I am not sure if you have got an early or a late L-jetronic, but take a look >at http://proffa.cc.tut.fi/~k124775/ which is the hompage of a Finish Alfa >Romeo nut.

Date: Mon, 6 May 1996 14:03:45 +1000 (EST) Subject: Variable cam timing Hi everyone, I've been thinking about the subject of variable cam timing, which seems to come and go on this group. The idea of electromagnetically actuated valves may be prohibitive in the amount of power it would use from the electrical system, what about a synchro-type system where the amount of slip between the driving motor (driven from the crank) and the driven motor (connected to the timing chain / cam gear itself) can be varied, giving a variable cam timing technique? it could be extended into having different timing for intake & exhaust, for dohc engines. The motors I thought of using would be some sort of induction motor, to eliminate the use of brushes. It may sound a little vague at the moment, what I wanted to do was to "throw the cat among the pidgeons", so to speak. Any more that I may add will come later. I wanted everyone's ideas on this for now. Thanks very much, Bruno.

We've blown a couple and SSI is supposedly on backorder -- have to race Formula SAE in one week. Please help, will pay cash.

Use 2 flappers and 2 controllers, each handling one cylinder bank.
