    put it in your bunghole

    EPP had his on the drivers side when he tuned mine, but he uses EFI Live (you already know) But I would assume it wouldn't matter what program you use

    Yeah, most tuners either put it post cat because they don't want to remove the narrowband o2 sensors pre cat (and don't want to weld in a bung for one tune) or they put it post cat because they use a tailpipe clamp on the dyno. Either way it will read a little leaner then the true reading but they either just roughly "correct" for it or just run with it!

    At this point, I'm not worried about it showing a little lean.
    When I really get into tuning, I'll have it welded pre-cat. For now, I'll keep it a bit rich anyway.

    Re: Wideband o2 Placement

    I have the LC-1 on the driver's side only hot wired into the NB o2 sensor.The purple is the one volt signal line, FYI...You will have to turn off the Heater option for MIL light codes..

    So far i havent had any issues, For better balance if you are goin to hot wire in the NB o2 it would be better to do both sides, but if your tune is correct then its a waste of money for the trim wouldnt be that far off...I have about 1-4 point difference between my two sides. Not a big deal...But if you blow a fuse you will go into HEAVY enrichment on WB side. Been there done that...

    The LM-2 is AMAZIN, got one to tune friends cars as well as my fathers boat...Wow very small, can be used alone or with PC and its Logable....Very happy with this buy..

    sorry to bring up a dead thread but how did you guys feed the wire from the sensor into the cabin?

    Under the dash. Big grommet for the steering linkage. Keep in mind the crazy ground offset we have on these cars.

    Re: Wideband o2 Placement

    Where did you guys get power and ground from, i just noticed that the fuse panel is in the rear of the vehicle. And what did you mean by crazy ground offset?

    I ran an 8 gauge power line straight from the fuse block up front. Then I have that powering another fuse block under my center console which is run by an ACC relay. This pic shows all of my grounds in an attempt to avoid grounding offsets (all in one spot, different lugs).





    The grounding offsets cause different readings on your WB gauge and HP Tuners then what the actual sensor is putting out. To fix this you need to adjust your gauge and HP Tuners to match what you are seeing in Log Works which is raw data from the LC-1. Get ready for a LOT of reading and it will eventually make sense.
