So you have the widebands in the up-pipes?

dont think you'd have 2 widebands in single downpipe.

close loop the vacuum cells and call it a day

Ya, they are different lengths.from the headers so I think it is a delay thing.

Closed loop my ***.....that would take forever to tune! Lol

closed loop, the haltech tries to target your AFR. that should be easy

I'm retarded. I was thinking open loop when I read that. Ya, closed loop is what I run with 15% correction both directions

i think raj has fine tuned his close loop down to 5% correction. with more time, you'll get those AFR to overlay

raj is a freak of nature. I'd love to have mine within 5% but then again i'd love to have a lot of things in life.

the whole map? we're talking his correction is set not to adjust more than 5% either way. I have areas on mine that are dead on because i spend time on them but the entire map to be within 5% is a long time tuning!

haha, not even close. Raj has 5% as the total correction the car can perform on ALL cells.

every cell is reachable

I have my dialed in withing 3% with correction set to +/-5%. It takes a while, but it is doable.
