STILLEN 370Z Supercharger System - Announcement!!!

Z eliminator

Detonation = new 4.5 stroker block. Its only $$$$$$$$.
stock stroker block 11.1 compression with bolts on's would make 375 rwhp easy.
No sc issues, no tranny issues. and i bet that it would sound great.
7 At + stroker, 4.08 gears 3200 stall conveter and a VB. That would be one fast Z.

Different mode? wonder if your car is going into that phantom limp mode from MAF location..yikes. One piece of info though that might be useful is that my car was idling high a few weeks ago and threw a code. I just reset it and the code went away and so did the high idle. Problem never came back.

So the high idle is because of the issue and not part of it.

Well, this has happened multiple times. Engine knock, high idle, cycle engine power and it's gone. Then it crops up again on no apparent pattern. And the knock is very audible....in traffic, i can hear it echoing off of the other cars! it's very embarrassing. And the kit with it's unique sound and the high idle, it sounds like an airplane when it is idling high and you're pulling into a parking lot. Also embarrissing.

check engine light

what code did you throw

RCZ

Car was behaving as usual so I figured it was just a glitch like a loose gas cap or something so I cleared the code and as I suspected it didnt come back. I didnt have the issues, but I figured I'd chip in a little info.

Osiris, your problem really sounds like your MAF's are getting funky readings. From what I've heard lately, it seems that those random code-less issues are most often due to this issue. I am surprised though that it's not putting your car in limp mode in the process. Instead you say it just knocks?

toner123

so in other words you didn't pull the code correct?


I gave him a list of steps to do over yahoo messanger. easier then going back and forth on the forum. I think he will find some results here. i know K&N airfilters are known for being maf sensor killers if there close to them since the oil they use screws them up. so i told him to clean them, run a fuel pressure test to verify fuel pressure is good then log files for maf voltage and a/f correction on banks 1 and 2

When my MAF sensor wasn't getting the proper voltages it immediately went into limp mode for approximately 10 minutes. I shut the car off, waited for a few minutes and turned the car back on. I find it weird that there's not a single check engine light... if the car does knock the ECU will immediately pull timing to protect engine failure.

It could also mean the MAF sensor is getting different readings then what the motor is actually seeing causing the knock issues. The MAF sensor is before the supercharger, so it will read a certain temperature, once the air hits the supercharger and pushes out through the outlet pipe to the throttle-bodies, the temperature is changed. Also, Stillen states the MAF sensors are suppose to be calibrated through the UpRev canned tune... who knows.

So this brings the list of enginen detination issues with the stillen kit to 2, is that correct? And if we are to believe the reports that stillen says themselves that the forums are only a very small part of their SC sales, whould it not also be safe to assume that there are other SC's out on the road that are having this issue but are not on this board. Art first it could almost be passiable that it was only one car and ya maybe that is it we all know there are "freak" cars out there that do weird things. But now we are on number 2. Not sure if the 2 issuesthey are behaving the same way but the question is to be asked will it need a software or hardware fix?

Wow, 159 pages. Did my best to scan but how does the stillen supercharger system work with the VDC? Any issues there?

Buzzlitonian

No VDC works just fine with mine. It may actually be squelching the power down abit to keep the tires from spinning. Z has been very stable on all kinds of road surfaces and weather.

wishihadnav

detonation isnt a problem...until it blow up..lol.

weiboy718

Anybody here running a boost gauge with this kit?
