LC-1 Wiring questions
Posted: Sat Nov 08, 2008 2:28 pm
I was wondering if it would be OK to wire the heater ground from the LC-1 to the heater control pin on the ECU. I am planning on using the analog outputs 1 and 2 from the LC-1 to input normal O2 sensor signal into D14 and a wideband input into B6 analog input 2 on the ECU. I have modified the ECU by removing R2 and R3 as indicated by the settings menu in Smanager. I also have the option of using one of 3 grounds from a conversion harness which run parallel to A23 A26 and B2 on the ECU. The Innovate manual recommends grounding the heater to the same source but separated from the analog and system ground wires. I guess I'm a little confused about the difference between the paralleled A23 and A24 ground pins and the paralleled A26 and B2 grounds on the ECU, and also the specific function of the heater control pin. Does it open after a certain time frame? Thanks in advance for the help!
