Default how about tuning with a wideband o2?

i have been playin around with the idea, lets see if im the only one out there!
ok im lookin it to buyin the innavated wideband o2 system and puttin an o2 bung into each of my exaust port, reason being so that instead of modifing the system as a whole tryin to get the air fuel mix perfect and chippin pistons why not do it like they do on the pro mod drag cars and be able to tune each cylinder on its own so that each cylinder is runnin the correct air fuel mix.
do that sound like it would work, i have thought about it over and over but i kinda wont to get a lil in put about it before i go and spend 500 bucks and get no results![/size

I have that very same wideband, and I can tell you it'* impractical unless you run and log all 6 at the same time. AFR varies too much based on conditions of the test. Doing one cylinder a day won't get you anywhere. You need to log all 6 at the same time and skew your injectors based on that.

Not worth the money.

Get your injectors flowmatched, and port-match your LIM to your heads. Then tune with the wideband in the downpipe.

You can't run a WBO2 what close to the cylinder. It can't take the heat.

It'* not too uncommon to have a WBO2 for each bank though.

If you really wanted to monitor each cylinder, individual EGT sensors would be the way to go.
