Do I need to get wideband o2's to get a decent tune? I've been having problems when she is cold like bogging and won't start right away. When she warms up she is fine. Don't get me wrong It is much better then is used to be. As long as it is warmed up.
wideband o2's assuming you have a wide band air/fuel ratio gauge to go with it, comes in really handy when tuning. you don't need one, but you need one to get the best out of tuning is how i look at it. You can go buy the seat-o-pants meter, but thats just never accurate enough to tell you if your running lean or rich. as far as cold starts, the o2's don't start working until they get to certain degree. i think its over 200*. So they aren't functioning properly until then.
I mainly use my wb for OL tuning. You have kamrf & lambse values to use for CL tuning. CBAZA has several fuel tables and they all have their own purpose. Here is enough info to get you started btw, there is some stuff on my site about adjusting the tables for starting probs and I know for certain I've posted here about this issue Stabilized is for normal temps wot Base is for start up until normal temps Start_up is an adder to the values of the base ... like a choke Grady
Could 19 lb. injectors cause a little tick or lifter like sound in my engine? It might be an exhaust leak also, I having a little trouble tracking it down. Thanks, Tom
