Decided to piggyback off the ecm for signal like on my truck,I just want to know when it leans out if I'm on the pipe so I don't hurt anything...this pic is at 10,160 feet and had to bust through some drifts to get here,I'm worried about the motor leaning out on the top end when I'm busting snow drifts at any elevation really...that's all I want it for..I.understand a wide band would be better for tuning purposes but I just want to know what's going on real time as I need to know ..
