View Full Version : AutoVE & going back to CL?

Just wondering - on the end of the AutoVE HowTo, it states not to do that step when you are using COS#3 or up ...

Why?

I was thinking of reconnecting the MAF and going CL, for one, last year a tuner who was here recommended it, and being somewhere with very varying temperature ranges over the year (10 through 30+ during the race season) and different heights, the MAF should help keeping the fueling in better ranges ...

Also, I think that even with staying in OLSD, certain values should be reset to stock, like e.g. Cat protection...

Any comments?

Temps and pressures is an old wives tale.
Afterall you already have a IAT sensor for temperature and a MAP sensor for pressure.
Its charge blend table you want to look at if things wander, not the MAF
Afterall why do Chrysler have 2million plus Hemi's out there with speed density from the factory if they dont work properly!?

Id leave cat protection off as well. Unless you do lots of racing with cats, in which case perhaps it will help protect them.

So how does the COS with OLSD effect changes when you go from say 5000 feet of altitude to 8,000 feet of alititude on the same drive? Doesn't the MAP set initially on start-up and not reset during a drive? I guess what I'm saying is there isn't a sensor that tells the computer the change in altitude during a curent drive without a restart without the MAF, is there? What does the chrysler system do to compensate? I would think they have something to calculate the changes since the last start-up.
