LC1 TS and gauge mismatch
Posted: Tue Dec 28, 2010 12:44 pm
Hi, looking for some guidance please.
I have my car idling with the LC1 WB connected. The gauge shows AFR~13.5 which seems about right. The TS read out shows AFR9.5-10. There is ~0.999v ground to signal on the LC1 signal wire and the MS2 O2 input pin. There is ~2.1v on the Innovative Gauge input pin.
Both the LC1 and Innovative gauge share the same ground which is the same as on the OEM NB 02 sensor.
I cant leave the car to idle with the WB control active as it tries to lean out an eventually it dies.
Both devices (gauge and TS) is reading right based on their input voltages (?), hence the difference in AFR, but why should the two outputs (wires) show different values from the same sensor?
Any help would be appreciated!
