Cheapo Opti?
I remember a post awhile back indicating that AutoZone or somewhere had optis for under two bills. Anybody remember where that was?
Has anybody taken the Optigrab down to the point of failure? Every time I chase one of these down, it winds up being the result of some horsecaca attempt to cut manufacturing costs. Example; 1996 Sonoma ZR2 electronic transfer case control craps out, told shift unit must be replaced at mega-bills, turns out to be a $0.05 pot metal collar on the stepmotor planetary gear reducer output shaft that disintegrated. $0.10 copper pipe fitting and Mr. Dremel make a replacement that's more forgiving and working just fine thanks. I've got a crackload of examples just like that.
My job is making complex electrical crap work while it's being hit with a fire hose. The Opti should not be a problem, but has anybody already done the legwork on reengineering this ill-conceived piece of refuse?

:yesnod:
In food-processing environments the FDA requires washdown where they hit literally everything with a hose that would knock you on your ***. Add caustic and corrosive chemicals, solvents and what-not to that, the electrical stuff has to be protected. Don't even get me started on high-temperature, severe-duty, or explosive environments where a spark takes out the whole building. The fact that GM took a standing nap on the Opti really chaps my ***. Inexcusable. No problem, I feex...

Re: Cheapo Opti? (rocketfinger)
there has been much talk about a system to replace the opti... and there are things that can be done to improve the present parts.
but the killer for replacement is the requirement that the opti provides a low res signal for the fuel injection...
now... to improve... the later versions had a vent system, that with some work, is adaptable to the earlier caps... and the idea of placing a bead of RTV on the seam between the cap and the body seems to work great!
so... yes... it could be improved. Why did'nt GM use a lost spark system??? I have no clue.
