I just had my autometer cobalt a/f gauge installed and was wondering what kinds of readings u guys are experiencing at idle and driving. Im not experiencing any lean or rich issues during driving or spirited driving. A little at idle but thought that might be b/c of the cam and when it shows lean or rich its for a brief moment with the 8 green lights on (rich) and the 8 amber lights on (lean), and then a showing of the stoichiometric range which is perfect in a perfect world. Im assuming the bouncing around of the rich and lean reading is due to the cams and that I believe it to be ok. What do u guys think

At idle I am usually 14 something then it bounces to 15 something. Driving, it will bounce to 16 something then drop back. I was told the only true reading is WOT. It really is all over the place but when I get on the gas it sticks to a number. WOT throttle I am in the 11's. My tune is still not 100% there, it'll throw signal stuck rich every few weeks and even throw the blinking o/d light now and then.

Your a/f will bounce around at idle and under part throttle. But still should remain within a roughly 14-17 range.

WOT is what you really want to watch, making sure you're not too lean.

yea mine seems to be what yours is. I kind of thought that most tuners had the o/d light thing figured out. That kind of sucks for ya. Who is your tuner. Hopefully they will get that figured out.

thanks man for your input

thanks buddy. I'll have to check that out when the air gets a bit warmer

JDM did my tune. I really am gonna try to datalog with the sct this weekend. I got all the cords and think I may have decifered the instructions. Jim has asked me me to data log so he can determine whats going on etc......

You guys that live close to a tuner are quite lucky. I hate reading all these directions, making custom cables etc..to datalog. I feel like I am in school all over again. That sh#t was decades ago. I would rather just pay somebody to tune it and be done with it! LOL
