STILLEN 370Z Supercharger System - Announcement!!!

LateralG'z · 08-06-2010, 07:41 PM

Dyno scheduled for Tomorrow at noon. Will try to have the results posted a few hours following. So far just doing a little initial tuning to help get the car prepared for tomorrow but so far so good.

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.

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.

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.

Kastley85891 · 08-07-2010, 10:30 AM

^exactamundo dude +1 thats why I would run 12:5.1 on E85 ;-)

Id be happy with 11:0.1 to 10:8/5.1 up top on pump, depending on timing and boost, personally I have never seen an EGT guage on a Z as yet but that is soo helpful when tuning FI.

This was my exact feeling on the kit as well!!....I am truly impressed with the power/Fit/Finish of this unit....great job Stillen!

Agreed except that small tuning promblem with the cars that have this kit and tuned by stillen are inoperable. Besides that its great to look at my car with this kit installed. Sucks i cant drive it cause stillen cant figure out how to tune our cars without blowing up the engine. Cool to look at tho.

GUTCH · 08-07-2010, 02:54 PM

Chris & HP Logic

Just to be clear, are you guys saying that your cars are producing figures as per those advertised by Stillen? If so, can you please post dyno results.

I'm not trying to to be smart, I genuinely want to know.

Bad news bears, we are having some tech. issues with Uprev with my ecu. The kit is great, sounds amazing, makes boost really early but we are having Uprev software problems again with my ECU. We pulled the plug till uprev can get some answers. I don't know how Chris handles this type of BS from Uprev. This is the second time they have cost him a bunch of money for software issues. He has done such a good job only to have this derail the build.
Will keep update when find something out

I thought Stillen was using a modified version of Uprev? So not directly Uprev at fault here.

We are using the normal version of Uprev, and doing a custom tune. This particular ECU ROM has a few bugs in it.

Yes it is fine to drive DD, it is actually a little rich in open loop or non load conditions but why drive it when or if I need power I hurt the motor and things are not running correctly. The car under any load is extremely rich 9.5:1 to 10:1. We hit boost a little and it came on early so that is sweet and makes me feel a lot better about the kit, but the Uprev fuel tables and left and right bank were going hay wire and were miss labeled. Uprev is pretty much on my **** list. But on another Chris did a great job, the kit looks great, the little boost we hit came on nice and early so I am now dying to have the car finished.
