Default Wideband 02 heatsink...?

I regularly get error code 8 with my LC-1 which according to the manual is overheating...

A friend has mentioned a heatsink you can make for it.

Anyone know anything about this?

Cheers



Mel

I doubt that you need to add a heatsink, try downgrading the firmware to version 1.0. I had the same problem and it turns out that there is a bug in their firmware (that they wont admit to). I had my LC1 sensor in the stock location and it ran fine like that after updating the firmware for several months before going turbo..

I've been running the LC-1 sensor in the stock downpipe bung for over 18 months, which includes several thousand street miles and about 10 track days and it's perfectly fine. You don't need a heatsink on a stock Miata. When you start burning a LOT more fuel is when you need to worry about moving it farther downstream and/or heatsinking it. Your problem lies elsewhere.

make this out of copper or aluminum:



screw the sensor onto of it, angle it so it's inline with airflow.

Innovate also sells a "heatsink bung extender" that spaces the sensor a little farther off the pipe.

Im SC. I actually removed my copper sink when I kept getting error 4's. In the end that was down to too much cranking. Removing it has caused no over-heat errors.

Stock location FTW without a heatsink, it's been like that for a good few thousand miles now with zero issues. Albeit the NB o2 bung is slightly more downstream that the NA.

Thanks Craigo, after a bit of play with my AFR targets it seems to have stopped giving me the error code.

Now on to the next problem :(..... https://www.miataturbo.net/forum/t43236/#post512592

Does anyone get error 8 with the latest firmware? My lc1 w/v1.0 is installed in the begi dp and lately im getting e8 every time i drive. I've tried different fuel maps and afr targets including the base pnp map.

I grounded the lc1 separately from the ecu ground and error 8 appears less often. I'm still paranoid about tuning if it is really damaged.

Switching the firmware from v1.10 to the older v1.00a fixed my e8 problem. The sensor was not overheating.

Bringing back a dead thread.
Where did you guys get the 1.0 firmware? I'm getting E8s after literally 30 seconds of driving. Trying to eliminate variables.

Awesome, thanks. Went 15 minutes without E8. Hopefully this fixes it for good though.
