SCT is superchips
SCT = super custom chips
superchips = superchips
2 totally different companies
edit:
o, i thought SCT stood for super chips tuning, my bad, i have SCT advantage, ive been emailing back and forth with my SCT dealer, and just posted on the SCTflash forum
oh ok… maybe it does stand for that (I know thats what it USED to be when Jerry first started it)… just confused me lol
but yeah… any luck with them? or any leads to go on? talk about wierd
lol… of course it’s probably something stupid causing your problem (a 2.00 fix or something retarded lol)
i dont think its tune related, the car ran great and then after my oil mishap its been prgressively worse and worse. ive cleaned everything but the intake manifold, and replaced the MAF, but still am having problems. i dont know. i hope plugs and wires solves it, but it seems load oriented, like i get really erratic load values at low throttle and low RPM
ahhhhh… I got ya… I thought the oil thing happened before you got it running right the first time.
what happened? (I missed the thread I think)
well, while i was buttoning up last minute stuff, i grabed the nearest piece of hose that fir my oil return line, and used it…turned out it was silicone and the heat of the exhuast next to it heated it to the point where it warped itself kinked shut, and backed oil through the seals and caked all my piping and my maf. so we cleaned everything out and tried getting it running right again, but then the PCV setup we designed wasnt working the way it was supposed to, and the car would blow alot of oil under boost because of that. so we ran a catch can instead, and cleaned the maf again. its just slowly gotten worse. and i dont know what the hell it is. i HAD figured we just cleaned the maf too many times and damaged it, and got a new maf, but it didnt solve a damn thing.
got the car runningthe first time
did the usualy check of everything possible
test drove w/ dataogging
did some adjustments to the tune
few more test drives and tune adjustments, while watching the open loop flag
took it out on soutwestern and did a few semi-hard pulls w/o going into open loop
car ran like a top, huuuge difference from last year
then the one day the oil return line decided it wasnt happy, and it kinked off some, allowing the turbo to fill with oil
thats when the probs started, we cleaned all the piping, cleaned the plugs, and did what we could to clean any carbon out of the engine (and there was ALOT of carbon in there to)
nothing has fixed it yet tho …
its got to be wiring related or something. hopefully new plugs/wires, and fixing the coilpack wires makes it happy again. otherwise im suspecting bad compressoin or something more drastic
hmm… I’m stumped to be honest, gotta be ignition or wiring somewhere.
yeah, ive been on and off the phone with skrapper, gonna try wires and plugs and the coilpack pigtail issue. general concensus is that should do the trick.
lol I’ll keep my fingers crossed for ya
definatley not plug wires. But TPS…hrmmmmmm.
actually… I bet ya it is especially if you said that it got all gooped up with oil
tried a TPS off my buddies spare motor, dont know if that one is shot too, but same problem only now i get my rpms stuck at 2000rpms for a few secs at stop lights and crap. i dunno.
any holes in your charge piping?
nope
and considering the maf is the last thing b4 the thriottle body, any leaks b4 the maf shouldnt matter
hate to say this
but having the maf before the TB is not a good idea… let me explain why
your MAF measures air flow… since the focus is a NA car the MAF assumes all air is at normal atmospheric pressure, and calculates its fueling based upon that
putting hte MAF in a pressured airstream will cause it to read a lower amount of air and thus a lower amount of oxygen then is actually present… thus presenting the car with a problem
i have never seen a turbo car put the maf after the turbo it is always before the turbo after the air filter
that way the air coming through the maf is at normal atmospheric pressure, and the car can read the true amount of air being taken in (all the air going into the turbo goes through the maf, thus all that same oxygen comes out and your car is much happier)
not only that but the MAF stays clean and away from the exess heat of compressed air that is probably killing it
Actually… that makes alot of sense
although it doesnt seem right that it was running good before all this though
I see your point Viper, and it makes sense…but, what about the countless DSMers that go with the 3" GM maf? That is placed literally inches before the TB. And the GM maf normally fits an NA application also. However, it is re-calibrated with a translator so that might be the key.
