Check what fuel settings? I am not sure what you mean.
Check what fuel settings? I am not sure what you mean.
The LC-1 has fuel type settings for gas, diesel, ethanol, ect.
Make sure it is set to the fuel you are using.
Sometimes these will change for unknown reasons.
Mine happened to do this today actually.
It was set to custom 1750:1
You will need a USB to Serial RS-232 Adapter
if you can't connect it to your PC directly.

Oh yah, I checked that. It was on gasoline. I am just going to try the free air calibration in the morning and see if that fixes it, if not, I will do the full heater/free air again. How would I tell if the O2 is bad?
Mine will drop connection and give Error8 or 9 under load
or AFR will read unreasonably lean @ WOT if the sensor is bad.

When my WBO2 was fried, I also got lean values (though it started out fine right after turning on the motor), I also ha occasional/frequent warm-up errors ... if you know anybody with an LC1, swap sensors and see if it works again ...

Well now my question is can I do a free air calibration with it in the exhaust pipe after letting it sit all night? This is also pre-cat.
You can but it's not the preferred method.
Some people rev the engine a little before turning it off
to evacuate the exhaust.

Alright, so driving today after a free air calibration it worked great for about 10 minutes of driving and LED was solid, then LED kinda freaked out and it gave error blinks, but they were sporadic. On the way home from work it was pegged at 20:1 AFR and fluctuating in that range, until again, about 10 mins into driving the LED started blinking again. This time it gave the actual error code of 3. So, this is saying pump cell short. It says could also mean overheating. What is weird is the the whole time it gave me this error LED, it would read the correct AFR. I am thinking since it is happening about 10 minutes after I have the truck running, it is overheating and that's why I am getting the code, but why would it not work before that? I am at a loss. I think I may do another heater and then free air cal. Any ideas?
