Frick I love MSIII, each EGO can correct each injector channel FTW!

yep, I could install an LC-1 on each runner and run ego on each injector.

Well, in theory you could. In reality, I suspect you'd probably have four O2 sensors rapidly getting flaky from being installed that close to the head. The hardware isn't quite as baller as the software.

Never had 1 issue with LC1's and OEMs use the same Bosch sensor just as close.

Bad installs cause the issues not the H/W it's self.

It's not how crappily people tend to wire up the LC-1 controller, well-documented as that trend may be. The sensors themselves are known to be heat-sensitive and that's why Innovate tells you to install them a couple feet away from the head, i.e. not in the individual runners of a turbo mani, and to use a heat sink.

I never have any issues with my LC-1 on the street either. It's only after about 10 minutes on track where it will peg on 15.1 and not move because the sensor gets overheated, and that's running N/A. If the street-only drivers really want the precision of per-cylinder EGO control and have the coin for three more widebands burning holes in their pockets, great, I agree it should work fine for them. But I suspect that the people who are going to bother with actually taking measurements of per-cylinder [anything] are mostly a subset of the track crew, and my experience suggests that <4 of those sensors will be outputting meaningful numbers after 10 minutes of manly driving on track when installed in the typically short runners of Miata turbo manis. At the least, you'd have to work out some killer heat sinking.

I have 5 widebands on my car: 1 LM-1 before the cat, and 4 LC-1s on my header, with the plain copper heatsink. No problems with overheating, either on the street (frequently doing 0-200km/h) or on the track (10 lap sessions).

If the copper is enough then that's good news for me. I acquired a little sheet of it after my last track day, just haven't gotten around to making the heat sink yet. I was kind of wondering how much of a difference it would make. How long (years, miles, track days, whatever) have they held up in your installation? Reason I ask is that I had no problems with mine for over a year, then this season it started heat-locking on me. IDK if my sensor is just going bad with age or if I'm just driving the car in a more manly fashion this season, both of which are likely.

other features I like:

LM-1: 4 years, 50k miles. Countless trackdays.
LC-1: 16 months, dunno about miles. Maybe 5 trackdays.

I'm supercharged sensor in the OEM location with copper heatsink as per manual, done 40+k and multiple trackdays. Not 1 issue
