Thread: o2 wideband

I have recently aquired an o2 wideband and have 550cc injectors with 255 fuel pump and i need help tuning my safc. I do have a datalogger (mmcd) but i hear its better to use wideband because i dont have a fpr and datalogging fuel trims will not work with a 255+ fuel pump.
I need help tuning with o2 wideband. I live in yuba city. Anybody know of a local shop worthy of a good tune?

That would be great if i knew how or if someone gave me a o2 wideband tuning guide but that wont seem to happen so i will pay with little money i have.

hmmm. that is pretty simple. Now all i need to know is.. HOW TO F***ING TUNE!!!!!!
I know more than enough about fuel systems. thats not the problem. its using the hardware.
did i miss the memo on how to tune for 10:1 all across the rpm range at different tps positions? cause everyone but me seems to know how.

It's about two threads north.

wow. o2 wideband. NOT logger.
"S-AFC Tuning for the 1G with a Datalogger"
its becoming pretty apparent that its impossible to tune with just an o2 wideband and safc. Is this true?

Jesus, its pretty apparent that you don't know anything about anything. Did you even read what it said. Tuning with WB/AFC and logger/AFC is pretty much the same, only you won't be able to log knock. Get a knockbox or TMO chip or something. Just do what peregrine said and tune to 10:1 on pump while maintaining no knock.
