Air/Fuel Ratio
I have a LC-1 with db gauge on my Mitsubishi Evo. The gauge reads from 13.8 to 15.9 at idle. This morning after the car was sitting off over night I turned on the ignition and the gauge read 22.4. Then when I turn it on the numbers climb to about 15-15.1 then its strarts .from 13.8-15.9. Do I have to do the calibration again? From the lc-1 plug to the free air cal? When doing the calibration both plug and sensor Do I have to reset it with lm programmer? Please help. Thank you in advanced.

Sounds normal to me, when the engine is off and has been off it will read 22:1. It will also read 22:1 under decel as the injectors are shut off. At idle or low load cruise it should hunt between high 13's low 15's

one of the problems you may have could be determined by looking at the fuel trims.
buy yes something is wrong with your closed loop idle it should bounce in a smaller range than you have. I'd do a recal just to know for sure if something is wrong there but in the mean time log short and mid trims. they may be called something else in your log program.

Like I have been telling you man. You have done the heater calibration and free calibration a bunch of times and its still not right. It doesn't remember your settings. My money is on the wiring. Innovate products are very finicky about the wiring and grounds.
