Ive been reading through my install instructions and I'm wondering if you guys have used an LED or not? I bought the wideband off a forum member and the LED was not included. I would still use a push button for calibration though. Thanks in advance.

 

You don't have to, but it's helpful. The LED blinks during warmup and blinks error codes. You can use a 10 cent radioshack LED too.

 

I have an LC-1 in my corolla and FC and have never used the LED.

My rx-7 has the sweet XD-16 gauge though which displays error codes. my corollas crappier gauge still blinks when it's warming up.

I don't think you really need it.

 

i also use the xd-16 gauge...

I just have the red digital gauge. Correct AFR readings arent something I want to be worried about. Ill give it a try with an LED
