AFR tuning tips

first off
Mattax thanks! there is a lot of good info there.

I have the same Innovate motorsport AFR but, mine is single channel.
I couldn't get it to work vary well at all, had the controler reflashed/updated flash. had a longer bung welded in but it would only work one or two times and then it would not heat up enuff to take a reading.
Frustrated i threw it on the passenger seat were it set that hole season of racing.
That winter i had to pull the eng for a coolant leak. the bung was welded in the collector of my header. what i notes was that the hole was torched to small, and the o2 sensor was being crushed slightly. It was crushing the tip of the o2 sensor but not enough to notice. got my bur out and cleaned up/straightened up the hole.
So, i broke down and bought another o2 sensor and installed it(.I had killed 5 before i gave up) it worked flawlessly!

Looking forward to doing some o2 recorded runs this year!!!!!
Which is why i bought this one in the first place. Didn't want to try and keep a eye on my tach, shift light and a o2 meter going down the track.

Just a fyi for someone who may have a similar problem.
Thanks again Mattax. I'm going to have to re read all of them links again before i start using my LM-2
