12 min tune

[Powder Monkey]

Can it be done with the stock o2 disconnected. I ask cos running Pcv and a blanked off o2. Haven't dynod yet will do but trying to find time. Am thinking it takes feedback
from o2 sensor during 12 min tune?

You can it wipes the fuel trim adaptations, it just won't be adding any more.

Wondering if that might be a good idea as new exhaust just been fitted

I think it would be a waste of gas. It is not going to help anything in that regards. Do you have autotune with the PCV? Or a canned tune for your setup?

There isn't a pcv tune for my setup so I'm running the standard roadster map at the moment. I have autotune and it is fitted bus as I think u know mate it isn't as simple as plug and play unfortunately. Having read through you have to set some kind of afr as a bench mark for it and that's where my knowledge fails me. In addition I'm about to put a tune ecu map in which is sorta kinda close to my setup. I think then I'll remove the map from the pcv and switch off the autotune until I can get it dynod. My concerns being the changes the autotune and stock
roadster pcv map may make to the tune ecu map could snafu things completely. What u reckon?

As long as you have a zero map loaded into the PCV, it won't hurt a thing loading a TuneEcu map that has fueling changes. It's up to you whether or not you leave it in when you dyno. Either way the dyno will make corrections to get the proper AF ratio. I would just make sure you are running something close for the time being so you don't cook anything.
