Ok, so the LC-1's OK. Does the AFR respond correctly if you test the MS on a Stimulator?


Matt,

I found that the wire I was using to go from the LC-1 output to the relay board had a kink in it. I replaced the wire. I still can't get a reading using the output 1 (after setting it to output the ...

First, could you check the voltage on the LC-1's output and let me know if that is reading OK?

Thanks for the reply, Matt!

I checked the voltages of Output 1 and Output 2. Output 1 is reading 0V, and output 2 is reading 1.8V (very close to what the gauge reads. So, that explains why I am reading ...

This morning, I was going through the settings in Tunerstudio, and saw the option to calibrate the AFR table (the only option I think I missed before). So, I tried setting it to the default LC-1 output, and updated the controller. Instead of reading 14.7, tunerstudio then read 7.8 when the engine ...
