Stillen FI Kit Review

wishihadnav

actually it believe its anywhere between 390-455 whp at this point..

It is amazing how the info people provided gets twisted. I believe from reading the posts and seeing the kit that it is nicely built, but just requires a custom tune to get the max out of it. The day of bashing this kit really needs to come to a end. There are customers now driving there car with this kit and stillens tune, and they are happy with what they have. IMO thats all that matters, so please lets move on from this.

Nope, just keep the boost low and drive her like I want to. There is too much BS about turbo's that too many in here run their mouth about! When most of it could not be more wrong, but thats ok. If anything I would like to keep the head count of turbo boost 370's low so I stay a rare breed! Hahahaha

Edit: You have to remember, with the GTM kit the tune is good to I think like 16 or 18 psi. If you have a boost controller you can dial in how much boost you want. So if you have a stock clutch, 99% of the time just run low boost unless a superchagred 370z pulls up, than boost up a notch or two so you can leave him in the dust like I do Dreamer hahahaha!

Edit 2: Dreamer 335's won't help you muahahahahaha! Sorry homie, I had too, if you don't remember you were the one who wanted to race!

Im curious what our numbers will be with the eighth tune. Like everyone has said before the only way to get decent numbers out of this kit is to custom tune it. Which i know now but not what stillen advertised as a turn key. The only person getting stillens "turn key" numbers is RCZ which he has custom with lots of supporting mods and the original pully. Everyone that has customed tune their kit is still no where near what stillen advertised. JUst seems kinda shady to me and i feel ripped off.

sigh, this is why i didn't want to post my latest update. i knew you will get upset one way or another.

tomnavone

no worries man its been a long battle with stillen for both of us. CUSTOM TUNE! Its the only way



After eight tunes and almost five months i dont care about the numbers as much as my car just being drivable. If i could do it all over again i wouldnt.

I bought this kit as a somewhat inexpensive upgrade compared to turbo and also more reliable than a turbo and with a simple flash tune i could get awesome numbers like the stillen test car with their tune that advertised in their press realease

Weiboy and myself are now on tune eight 5 months later and the only way for this kit to work is to custom tune so their goes your warranty and stillens off the hook. I just feel cheated and theirs nothing i can do about unless i want to give stillen $1000 back as a restocking fee to return it

Im going to stillen to get a dyno it seems to add a good 30 - 40 hp to your numbers.

look Tom, i simply don't care about what kind of numbers i'm making, i got over that **** and just as long as my car drives fine i don't really care if it's making 410 or 375 period.

wishihadnav

the problem is that you guys are on tune#8 and it still doesnt drive very well...detonation of any kind wouldn't be acceptable imo...please just go and get a custom tune like RCZ and be done with it..

Engine knocking
-----------------------------------
Knocking (also called knock, detonation, spark knock, pinging or pinking) in spark-ignition internal combustion engines occurs when combustion of the air/fuel mixture in the cylinder starts off correctly in response to ignition by the spark plug, but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front. The fuel-air charge is meant to be ignited by the spark plug only, and at a precise time in the piston's stroke cycle. The peak of the combustion process no longer occurs at the optimum moment for the four-stroke cycle. The shock wave creates the characteristic metallic "pinging" sound, and cylinder pressure increases dramatically. Effects of engine knocking range from inconsequential to completely destructive. It should not be confused with pre-ignition (or preignition), as they are two separate events.




Abnormal combustion
------------------------------------
When unburned fuel/air mixture beyond the boundary of the flame front is subjected to a combination of heat and pressure for a certain duration (beyond the delay period of the fuel used), detonation may occur. Detonation is characterized by an instantaneous, explosive ignition of at least one pocket of fuel/air mixture outside of the flame front. A local shockwave is created around each pocket and the cylinder pressure may rise sharply beyond its design limits. If detonation is allowed to persist under extreme conditions or over many engine cycles, engine parts can be damaged or destroyed. The simplest deleterious effects are typically particle wear caused by moderate knocking, which may further ensue through the engine's oil system and cause wear on other parts before being trapped by the oil filter. Severe knocking can lead to catastrophic failure in the form of physical holes punched through the piston or head (i.e., rupture of the combustion chamber), either of which depressurizes the affected cylinder and introduces large metal fragments, fuel, and combustion products into the oil system. Hypereutectic pistons are known to break easily from such shock waves.

Detonation can be prevented by any or all of the following techniques: the use of a fuel with high octane rating, which increases the combustion temperature of the fuel and reduces the proclivity to detonate; enriching the fuel/air ratio, which adds extra fuel to the mixture and increases the cooling effect when the fuel vaporizes in the cylinder; reducing peak cylinder pressure by increasing the engine revolutions (e.g., shifting to a lower gear, there is also evidence that knock occurs more easily at low rpm than high regardless of other factors); increasing mixture turbulence or swirl by increasing engine revolutions or by increasing "squish" turbulence from the combustion chamber design; decreasing the manifold pressure by reducing the throttle opening; or reducing the load on the engine. Because pressure and temperature are strongly linked, knock can also be attenuated by controlling peak combustion chamber temperatures by compression ratio reduction, exhaust gas recirculation, appropriate calibration of the engine's ignition timing schedule, and careful design of the engine's combustion chambers and cooling system as well as controlling the initial air intake temperature. Knock is less common in cold climates. As an aftermarket solution, a water injection system can be employed to reduce combustion chamber peak temperatures and thus suppress detonation.

I think it's our fuel over here. I might wanna try using some Octane booster and see if that helps.

Regardless of the minor knock I'm having the car is running well, it doesn't drive like crap as others have stated. As you can see Stillen is getting very close in wrapping up their tuning issues cuz their tunes are getting better one after another. I have no complaints on Stillen's customer services whatsoever. I'm able to reach someone anytime of the day or night. Giving them an A+ in my part and thanks to Josh@Stillen for hooking me up with the AP Racing BBK. Them bad boys brakes very good!

They should account for the octane you will see in CA, which should be perfectly easy since they are located in the heart of CA to begin with and deal with our 91 octane gas every day. It should not detonate or knock regardless of the fuel you fill it with, granted you should fill it with the highest octane available to you in my opinion.

I always fill it with 91 Octane. Nothing less! THey're getting close to fixing it

christian370z

Very nice, is this supposed to be the final tune #9 at this point?

i really hope so!
