LC1 not holding calibration.
 

First real issue I've had with the LC1 in 30k miles of use.

The issue manifests itself either during highway cruise OR directly after a hard pull, such as banging off the rev limiter in 2nd, snapping off a 2-3-4, during dyno pulls, or on track. The DB gauge will either read rich under moderate throttle, like 8:1, or it will read wildly exaggerated numbers, such as 18-22:1 under light throttle and 8-10:1 during moderate throttle. Recalibration usually fixes the issue, but after doing a heater calibration this weekend the issue is back after 48 hours.

Time to replace the sensor or the unit?

Quite strange, I've never heard of people having problems with Innovate's products.

maybe it's time for a heatsink on the sensor....

If its giving you an error 8 then its time for a new sensor. Those are the same issues I had. Soon it will just stop giving you readings 5 minutes after first start.

You havent been here very long.

I have had nothing but headache with this piece of shit.

Nah, but I'm no stranger to forced induction. I hear nothing but good things and suggestions about it outside the Miata world. Interesting to see people NOT backing it.

I'm curious how close your sensor is to the turbo. I see people installing them pretty much right after it all the time, which obviously it doesnt like. There isnt too much you can do to protect it from heat, outside of putting it further down the stream and a heat shield.

Also, does your exhaust rattle or vibrate a lot? Thats the only other thing that I know of that could prematurely kill an O2 sensor.

I'de say the sensor is shot. However, I'm dumb
