Thanks for stopping in.
I bought a wideband the other day because I worry about A/F even on off-the-shelf maps. Anyway, I have LC-1 mounted and 75% wired. Question is: what is the BEST wire to tap for power? The manual calls for switched +12V. I know I could use any wire when the key goes to "ON" or "ACC" for that purpose, but from what I gather, this power will initialize the LC-1 controller and preheat the O2 sensor. Therefore, I would not want +12V switched on "ACC". Is "ON" my only choice? Is there a wire that only goes hot once the engine is started?
On a sidenote, do factory O2 sensors preheat when the key is "ON"? There's been many of times I had the key in this position while testing various electronics, starting ROMraider (connecting to ECU to configure), etc. I don't want to risk burning up the sensors! I guess I never really thought about it until now!
