The case of the red-hot glowing header pipes...

I should have my LM-1 by next Monday. In the meantime, can somebody tell me a good way of knowing when you're actually adjusting the enrichment screw (when it's actually engaged)? It's kind of awkward because it's spring loaded and you have to insert a 3mm allen and push down (approx 18mm) to engage the wrench. Clockwise for rich and anti-clock for lean. I tried to just richen it up a tiny bit, but don't know if I actually did it. For a screw that is supposed to be as sensitive as they say, it's got an unsensitive feel to it!!!!!!!!!!

S-man,
When I enriched my car I eased the allen wrench down into the hole until I felt the wrench engage the allen head. Then I pushed down as firmly as I could without useing excess force, and then turned the screw about a quarter turn. I then let the screw spring push the wrench up and I turned it again to feel the difference. It was different from the engaged feel. I agree though, that the Porsche engineers could have done a little better job. LOL

just a word of reinforcement to the wise... and you appear to be Sand_Man going so far as to get the LM-1 unit.
DEFINITELY put a meter on it after adjusting. I played around with that studip 3mm wrench adjuster thingee for a few months trying to find the best place. well needless to say, I was all over the map: too lean, not so lean, lean... never right. I was always afraid to turn the damn thing to much. the car always had a little surging feel at steady pedal... 3000rpm... most noticeable in 2/3rd gears.
Finally went to the wrench who set it at 3.5% and pull the O2 sensor off-line.
I don't have any power mods to speak of, running 0.8 bar spring and don't track it. so I'm not worried about on-boost enrichment... yet.

I agree with Gino. Get your LM-1 in and then adjust. Also, when you initially set your CO you need to do with engine warmed up, adjust, drive a little, then recheck. You'll also need to record with LM-1 for a while (maybe a minute) and then take avg reading because little change in AFR are pretty big CO jumps --> AFR 13.2 = 3.5% CO, AFR13.38 = 3.0% CO. Below is link for conversion chart. btw -- nice pics. were you camera man?

There are a couple of options...I'm just going for the stand alone test unit...not permanently connected.
