Reid, no difference - that's what Smiths called them when they came out. That's a reconditioned gauge as used in Triumphs. I liked it instead of the current one Moss sells because of the vintage look.
What I am thinking is to use the LM-1 to setup my BJ8 to get it to run better.
I overhauled it and went 60 over on the bore and it seems sluggish. My thought I’d to use the LM-1 to get readings at idle and through the cruise and power range and if needed buy special needles for the carbs. I will only be able to get readings by making two or more runs and inserting the probe in each side of the exhaust. My BJ8 is running the same exhaust setup as original, left side for the front three cylinders and right side for the rear three cylinders. The readings would be downloadable to my PC for viewing. I don’t want to add bung holes in the downpipes if I can help it.
The LM-1 isn't listed as a current product on Innovative Motorsports website. Typically, oxygen sensors have to operate at higher temperatures than the end of the tailpipe; that's why bungs have to be installed.

John, pretty sure this isn't the case. The MG tuners in the thread referenced above are using LM-1 or LM-2 with a 2-foot extension which goes far enough up their single straightish pipe so as to eliminate the possibility of outside air mix. IIRC, Gunson makes such a probe-type AFR sniffer.
Any thoughts on a DIY version of the Gunson insertable probe (and having just had my annual physical, kindly avoid remarks about colons and prostate checks). Doug

I'm using a Innovative LC-1 on my EFI car to help with the tune. It's great having real time A/F ratio numbers when your looking at the various combinations.

Patrick, I've never tried one on an SU car so can't say for sure. But, I it would certainly seem to be good info to have on any tune... real time A/F ratio info. After all, it's all about the gas/air mix and how well you are burning it (okay, ignition comes into it :tennis… but you get my drift.

HP - your video with the AFR meter shows a flat spot at the beginning of a rev.
Am assuming the EFI computer programming can take the info from a data logger and write an AFR curve which will offset the ups and downs for a variety of driving. This is the stuff that drives the SU tuners nuts when they're modifying specific parts of needles for specific needs.

Steve, yes as I mention... the video was about 15 minutes into it. While it started up amazingly well with little adjustment to the mapping tables in the ECU, there is much to do. The engine, as seen in the video, goes super lean at throttle tip in... all that can be adjusted out with the fuel maps... harder to do with SU's but a key piece of information nonetheless.
