2 ?'s Downsteam O2's and map tune only...

Unread post by Artisan »

Any pointers on shutting down the downstream o2's, and is a speed density tune possible deleting the maf?

Afaik cbaza doesn't have downstream o2 sensors. I swear mine didn't.

No way to run speed density with a MAF ECU.

true, no rear o2s

You can run alpha n in failed maf state.

What are you trying to do?

Is Alpha N safe to run with boost? Is it possible to run in RZASA. I had asked you a couple years ago about this in RZASA and I thought you said it wasnt really an option. Maybe my question though was more specifically about using a MAP sensor with RZASA and dropping the MAF but what I gathered was it really isnt something I should be pursuing.

I was more looking at doing it in my 57f100 that has a carb style throttle body and no boost(for a while). I wanted to be able to run a traditional style air cleaner instead of a carb hat with a tube and maf.
