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

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.

 

Sorry guys i didn't make it clear, i'm supercharged and have only just started my logging/autotune...

You could try reading the manual....the heatsink is detailed in there

 

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.

 

My Lc-1 was fitted and calibrated for me Mr Slow but that was my next option....

All sorted now.

Cheers all.

 

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.

 

is the big fat connector thing near a heat source?

 

the lc1 controller is in the interior by the console. the sensor has worked fine for a year. im going to try a different ground.

 

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.

 

Or just buy the darn thing here:

Thanks.. that's much cheaper than the bung extender.

 

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.

 

Try this. Change extension to *.DLD It wont upload the .DLD format.

 

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