just making a point that you obviously pay attention to how your car is running to run as well as it does. IMO experience with the wideband, it will not show lean cylinder to rich cylinders. my six pack has jetting all over the place. i do what i have to do to make all cylinders look equal. a wideband just wont tell you that unless you have bungs in all cylinders.
as for guys washing down cylinder walls, sure, i know many bracket racers that slap something together and as long as they can run consistantly thats all they care about. that makes me crazy. puffing black smoke driving around the pits and they dont care. then i see other guys times pickup as the weather gets hotter because there car is so lean.
i'm not saying not to have one, i have one in my car and its ON every time i go for a drive. but can it fine tune a crossram or tunnel ram? it may help a little but you wont get your tune right unless you look at plugs. if you only use an wideband to tune, you could have lean cyl and rich cyl and not know what is going on at all
Actually a good point. A wide band looks at the average, and not each cylinder and obviuosly you want to stay within a range, but there are those of us that have intakes and carb set-ups that not all cyclinders are equal, and this is where more work is required. I try and stick with intakes that don't require a tone of work to get the plugs to look even. For the most part, on a single plane intake and only one carb, the plugs should be farely close...If not, there is more work to do than just tuning the carb for best average A/F. There is more to it than that. Most bracket racers are not satisfied with "runs ok" and we like all our plugs even, but a smidge lean. Our temp swings here in one day can be too much to want to change jets every time the weather changes.
