unpluging the o2 sensor
Ok well for you who know about it when you unplug the o2 sensor the car shifts really hard and is cool but does it hurt the car that much?? thanks
|
well we shut the o2 sensor on my header off, it keeps trippen the higher flow of the exhaust. depends which o2 your turning off. um you can shut it off or unplug it you wont know what your running then. you might be running rich or lean. why does it shift hard yours is the auto right. hey man you work that tune it i sent you i think it was you. but hmm.

Yea i have the tune but im going to il on vacation and hahn is right down the road so im going there in july and having them do it all for me but thanks for the help man and its the o2 sensor on the air intake and yes im auto.
|
well thats i think a maf sensor not o2 if im correct its totally different then whats on the header and dp. why would you have to turn that off or unplug it? what intake you running. i know when i put my gmpp intake on and just plugged the sensor right in there. and i ran it for like 2weeks b4 more parts came and without a tune till a month later with injectors. i never got a code or cel.
well if you just going to hahn for a tune and some work. then you wont even need my file. they can just dyno tune yours and itl be alot better then what i got. cuz they can fine tune it. you might want a baseline run then put all the parts on there or something i dont know whatever you want. ryan. |
Ok maybe it is a MAF then and i unpluged it one day just fucking around and the car has alot of balls now it shifts hard and i can spin them into second but i think it might be bad cause it shifts so hard. And yeah hahn is doing it all
|
well plug it back in is a stock airbox it shouldnt have any problems. and if its a gmpp intake shouldnt have any problems either. i just know the aems, injens threw a couple cels.

its stock and i unpluged it cause i was making my own intake but put the stock back on and i unpluged it to show my friend how hard it shifts and i liked it so i just keeped it unpluged
|
well i would plug it back in, it doesnt seem like it should be shifting hard for an auto. autos should shift easy and smooth, your car might actually throw a cel or something cuz its unplugged but i doubt it. yeah i would plug it back in for now. probly not good for it. anyways youl have to plug it into something anyways. better not ruin the car b4 you work on it lol.

haha thats the truth cause it would be my luck i would get all the way up there and something will brake.

Im a little confused by this thread. I could be wrong, but I think if you unplugged your maf the car would run like a bag of crap if it ran at all, since the maf senses how much air is coming in and then tells the injectors how much fuel it needs. also harder shifts with an auto are better for the trans because the number one killer of auto trannys is heat, and smooth shifts are done by way of clutches slipping which causes heat. but it would be harder on driveline parts after the tranny cuz theyd be getting shock loaded.
|
yes with the maf is plugged into the cai which senses the air flow thats right. yeah i thought that if you unlugged it it would run like crap thats why i said plug it back in. i dont know much about autos. yeah i know heat is the killer. just i thought a easier shift for an auto is better but i dont know.
ryan. |
i would plug it back in immediately, and don't ever drive around with it unplugged again.
|
yup i agree.
ryan. |
i already did, thanks for all the help.
|
hey man hows that ride runnin. get that dyno and those parts on yet.

Its not the MAF, its the IAT sensor. GM has the TCM set up to vary tranny pressures according to air temps to keep shift quality consistenst, so the car always feels the same shifting even if its really cold or hot. When the car looses the signal the TCM commands full line pressure all the time, making all shifts really hard and fast. NOT good for the tranny and will cause reliability issues down the road from the extra wear. I guess it would be a cheap mod when you are at the track though.
