Yeah! I feel you! Driving down there not knowing what kind of risks you're taking in damaging your engine is not a very good feeling at all. My butt kept on squeezing together whenever I felt the lag and hesitation lol.

It's weird how you're having issues and you're an 6mt also. Most of the people are 7at that is running into problems.

Sorry that you guys are going through all these headaches.

have you gotten an independent dyno after the fix?

Not yet, my local tuners dyno is down and I'm waiting for him to fix it then I'll get it dyno

Stillen was much more active in this thread before kits started shipping..

Is Stillen and their dealers still selling kits? They should have a freeze right now on any new kits while these problems are worked out. I hope this is the case.

weiboy718 · 08-06-2010, 11:24 AM

I'm pretty sure they're gonna come up with something very SOON.

LateralG'z · 08-06-2010, 12:38 PM

The kits are on hold I due know that, which is BS because the kits can installed and the tuning can be sent later.

LateralG'z · 08-06-2010, 12:42 PM

It does sound like Stillen is getting things handled correctly with the Uprev people involved. I like uprev but i have my complaints about it so when christmas comes, this guy is looking at Haltech or something else that gives me a lot more control of the ecu.

Phimosis · 08-06-2010, 01:44 PM

I think it will all be sorted out in due time. The lag, bog, black smoke and unburnt fuel
smell are no accident. It's from setting the mixture rich.... Mine was running at 11.1:1. Ignition retard is also involved in that bog/low torque output setup and sends unburnt fuel into the exhaust. When a car runs like that, it runs cool and without detonation. It's "safe", but is low on power and has poor throttle response. If you leaned it out to 12.5:1 and advanced the timing 5 degrees or so, the car would spring to life and be a lot closer to emissions targets, make more power, have better throttle repsponse and get better gas mileage. Independant tuners are tuning the car this way and having good results. Like RCZ, right? What that tells me is Stillen either has evidence that damage is occuring under high rpm + high boost conditions when mixture is leaned out and timing is advanced, or they just suspect it and are afraid to lean it out for fear that someones engine is going to blow up and they get blamed. That becomes a PR disaster. If someone 's supercharged Z blows up with a stillen kit, but a tune from someone else, they can easily deflect blame and say it was improper tuning and say that none of the cars that they have tuned have had problems.

Thanks for the update seems stillen is being very quiet about this problem and when I should expect a new tune. They told myself and my shop its safe to drive but I decided last week just to garage my car and not drive it till they figure this out. Is your car still down there at stillen?

LateralG'z · 08-06-2010, 03:09 PM

I agree 100%

Looks like its supporting mods only for me this year

Hopefully all is sorted out soon.

Kastley85891 · 08-06-2010, 07:04 PM

Are there people tuning FI Z's at 12:5.1 at WOT? on pump gas?

or was the comment in bold based of the timing advance thoughts?.
I agree the timing would make a difference to drivability where able to add it in, but 5 degs on pump gas with a lean mixture would generally cause problems, even as boost builds.

Personally Id be happy on E85 to add in 5 degs and run 12:5.1 flat

Not knocking any of your post but a little surprised.

Any one got some logs yet of these cars they could email me so I could graph them up, Id be interested to see the timing curves and fuel targets etc, I can post up data in seperate thread if anyone is interested in seing it.

Seb@SZ · 08-07-2010, 01:55 AM

12.5 A\F would be way too lean for a forced induction engine especially one with high compression like our engines. I can see that mixture if someone was running C16 race fuel.

Phimosis · 08-07-2010, 06:29 PM

I didn't mean literally that is the number that tuners are sticking with throughout the entire rev range and under any boost condition. My biggest complaints have been about driveability at low rpm range where not much boost is being made. At 3,000 rpm my car, under boost is making 30 lb/ft torque less than stock and it's running 11.1:1 there. If it was leaned out in the midrange, it would act civil, make more power and get better mileage and be closer to emissions targets.

My car does make 422 whp at 7,500 rpm. That part is ok. I'm not suggesting they lean it out at redline. It's under 5,000 rpm where the tweaking with Stillen's tuning needs to occur. If you look at their press release, they are getting 340 lb/ft or torque in the midrange, where my car is only making 280 lb/ft.

Thanks for clearing that up as it did not seem resonable as originally stated.

I can understand you fruastration dude on your performance.
I would take control of the tune and not run Stillens although, must agree a 'turn key' package should be closer to dialed and more repeatable.

I can not comment farther on my own path to fix this as I am running a bone stock Z and for that reason I am sick with envy of all you members with FI.
Good luck with it, interested to see final fix.
