I can understand his methods would make it easier as a professional tuner with time constraints. But dont agree with his logic that fuel trims will mess up your part throttle & WOT tuning afterwards if you use a wideband at part throttle. If you dial in your o2 sensor switchpoints, you should be able to get your narrowband sensors to correlate with the wideband. This will stop the fuel trims from messing with your finished tune.
Joe, I believe he wants PE enabled to prevent any chance of the pcm entering closed loop. Just another way to skin the proverbial cat.

So if the PCM is in PE mode it cannot be in CL mode, as a matter of convenience...
That's the impression I get.Originally Posted by joecar

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

hmmm.....im confused.....if you put the commanded afr to stoich in pe mode, would it switch to closed loop?
so i got another one that wont go into semi close loop any help would be great
Can you post a log file?
here it is
There is nowhere on that log where you are commanding stoich. This is necessary for STFT to become active.
This is because you are commanding leaner than stoich in the cruise cells in the tune.
your exacly right but i cant find anywhere in the tune that would be making it come out of the fuel vs rpm table. thats where im stuck.
