How easy is it to install a AEM wideband AFR

Apologies mate, I stand corrected.

 

I must say that it doesn't sound like a very good bit of kit in that case. For a start the reason for an ignition live and a battery live in every gauge I have seen/installed is to keep the current draw at an absolute minimum from the ignition. It is neither fused nor gauged for anything other than switching. Sounds like a massive howler from AEM IMO. I would be selling it and buying a decent one.

 

No worries we cant be right all the time.......

I have always used Innovate LM-1 and LM-2, and they have just ignition live and earth, whether as a fixed, or hard wired via cig lighter, they have a calibration and settings memory, but have no need of a battery feed to retain them.

 

I've got the innovate lm1 and the gauge has B+, Ig+, earth and illum. My gauge dims when I turn the lights on. Fitted it myself other than the welding.

 

Edit: I think it's the LC-1 I have actually. The small unit with the 3.5 mm jack. I'll check how I have it wired when I go in. I did all 3 gauges at the same time.
