I have an LM-2 I'm having some troubles with. They seem to have disabled their forums so any google searches for info turns up the first two sentences of a solution and then a dead link.
Sorry for the double post from the other forum...
I have the O2 sensor that came with the unit and a brand new one I picked up today and I cannot get either one to calibrate. I updated the firmware to the latest release. What happens is after power-on with the sensor in free air (according to the instructions), it will start the Wxx counting where xx is percent of warm-up. It gets to W65 and just hangs, gets to W65 and then throws an E8 error code, gets to W65 then to CAL (good?) and before I can push and hold down the MODE button to access the sensor calibration screen it will throw the E8 code or do it right after I start the calibration.
Any LM-2 gurus out there who can help out a padiwan tuner?
