Anyone tuning with the LM-1 WB O2 sensor?
Anyone tuning with the LM-1 WB O2 sensor?
Have you hooked up your LM-1 yet? I've got the LM-1 and have been using it as a wideband for a couple weeks. But now I want to tune and not sure if I should connect the LM-1's signal ground directly to the grn/blk O2 sensors signal ground on the ECU harness. Because the grn/blk wire into the ECU is shared by a number of sensors.
