In my quest to further improve my emissions chips I picked up an Allen Smart Engine Analyzer with 4 gas exhaust gas analyzer and need a little help with it. The pc boots up okay in the engine analyzer portion (the top box) and has been updated to the version 12.something database of cars. Haven't hooked up to an ignition system yet but I assuming (yeah, yeah 
) that this part is okay. The serial cable is in place to the exhaust gas analyzer (the real reason I bought it) in the middle box, and it turns on and blinks the front panel lights through some sequence for a few seconds and then settles into two lights lit, the local light (top left) and the warming up light (bottom right) and then sits there forever. My understanding is that until it finishes warming up it won't go into network mode, and the SEA can never find it and just waits forever. Some net digging informed me that both Bear and Allen (and I think OTC) have been bought by SPX, and SPX no longer supports these units (it dates from the mid 90's). Their web site points to Superior for support on these, and somewhere in there I found a FAQ that said that the most common cause of this is a dead oxygen sensor. Apparently they have a finite life (guarranteed for 36 months by Teledyne, the manufactuer), and when they go dead the exhaust gas analzyer refuses to finish warming up. I invested $75 in a new sensor and installed it last night, and after 15 minutes it was still not warmed up, sigh.
There seems to be good flow through the sample hose, and I put in a new filter anyway just for luck. Right now I do not have a cylinder of cal gas connected, but I believe I only need that when I am actually calibrating the unit. Does anyone have any suggestions (besides either give up or call SPX for a service call)?
