STILLEN 370Z Supercharger System - Announcement!!!

Phimosis · 08-07-2010, 07:29 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.

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.

Thanks, I hate being a guinea pig. I do believe all our issues can be blamed on Uprev, that is why they are at Stillen. These sort of things make me really iffy about doing this. I am hoping Haltech has something for the 370 soon. Any updates on your car?

not yet im hoping they will figure it out next week i miss driving my car. We should do a meet with all the failed stillen superchargers.

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.

Lol not a fail, just technical issue that are kind of out of Stillen and definitely my hands. Typical stuff when being some of the first to buy the newest stuff. Software can be a pain, I deal with it all the time at work.

RCZ · 08-07-2010, 09:41 PM

Hmm, starting to wonder if this is actually Stillen's fault or if Stillen is covering up for Uprev and not throwing them under the bus..I'm sorry guys, but making a tune for this kit should not be a difficult task, specially so when you've been tuning cars forever like Stillen has. I highly highly doubt this is a problem due to the incompetency of Stillen Engineers. Do you all think they just forgot how to tune cars all of the sudden?

seriously? you only made 280lb/ft of torque?

Why wouldnt you do a custom tune specifically for your car? It seems that all successful projects have been done that way. Im ordering the kit without the tune so that Jack at HPlogic can tune ir right. Thats the same thing RCZ did...

no warranty if someone besides stillen tunes your car and it blows up your **** out of luck. i believe its a 3 year 36,000 warranty. I beleive RCZ is the only one on this forum that has successfully tuned his car from an independant party. RCZ has the golden kit its the only one that works. Im curious if RCZ changed out the old pully for the new pully and gotten the same dyno results with the new pully that they are shipping with the kits now

Chris is it a particular ROM ID #? If so which one?

thanks

I dont think its the kit... I think its the tuner knowing whats right. I believe he has the old pulley.

If my new Sync Navigation fails in my new Raptor - do I call up and blame Microsoft or take it to my Ford dealer?

Stillen designed and sells this kit. They SHOULD HAVE done enough testing on different vehicles to catch any tuning related problems. This is 100% on Stillen - don't even try to place the blame with someone else.

I am almost 100% sure it is Uprev with Stillens canned tune which is why they are there, I know Uprev is all F*** up on my ECU and I am not using the canned tune.
