LC1 Issues
My car has been running about 11-12ish AFRs under boost. I have an LC1 hooked up to a vgauges AFR gauge. It was displaying fine for a while and now it shows 22.2 all the time. Sometimes it will flash 7.whatever. I also hooked it up to freelog, set all the values in freelog and freelog only sees 10.0 all the time. I have a feeling my O2 is bad but wanted to see if anyone else has seen this. I pulled it out, I see nothing pluged in any of the holes. The sensor is clean over all. I did the free air callibration again on it and this didn't fix anything.

Ground is good?

Re: LC1 Issues
I'd try reinstalling the firmware and setting up the anolog outputs again.

Re: LC1 Issues
If the sensor is bad the LC-1 will throw a code.

Re: LC1 Issues
That's how mine has done everytime the sensor has went out, either pegging out to extremely rich or extremely lean...That's with the JAW and now the LC-1...

Re: LC1 Issues
This is offtopic, but I was wonderin' if you could datalog if you had the LC1 setup AND the SSI-4? Or at least monitor AFR's in relation to RPM's via laptop. Or would you need something else as well???

Re: LC1 Issues
um yeah. O.K

Re: LC1 Issues
SSI-4 can read RPM's on mostly any car. Its just that nobody whos' done it correctly has posted how-to on the innovate forums, only the failures have.
You put the plug in the serial-in port on the LC-1, connect it's serial-out to the SSI-4 serial-in, then connect it's serial-out port to the laptop. Open logworks, do the required crap to set both up (update for sure), and you've good to go. |

Re: LC1 Issues
+1 to reloading firmware and a free air calibration. LC-1's are sensitive to voltage spikes and noise. Is it wired up such that it's on with key in run AND start? If so, that's probably why it corrupted the firmware. Try on in run position only. Not sure of your engine management but with my megasquirt I just enable decel fuel cut, bring the motor to say 5K in fourth gear, let it decel for 5 seconds and then recalibrate. Works fine and I don't have to jack with removing the sensor.
