I've read people have lost power with it, in fact I've seen dyno's of it. I haven't seen anyone affirm it does make power.

I like the concept and idea of it, and Stillen usually makes solid products.

I'm looking for anyone with dyno or even butt dyno evidence of this part. With or without Z-tube is fine.

 

Brian, I haven't seen anything negative against the Stillen. It is well designed, and is better in power than the stock. I have seen dynos of it, and it does produce more power, about 10 hp I believe.

Check this thread out, this is the one that rose a lot of concern.

I have yet to hear any negative issues with this intake from any of my customers so far. Dyno's will vary depending on how the car is strapped down, tire pressure, how warmed up the car is, etc... so there could be some variance there, or maybe in the fact that he just recently reset his ECU and it hasn't been able to adapt to the changes from the intake?

Thanks, well to be honest, I purchased the intake, ironically from you about an hour before I posted this. Mainly because I like the stealth looks of it and from theory it sounds like it would work well. Your price was reasonable so I purchased it. Now I'm trying to decide whether to install it or not; most likely will.

relax guys...

he's only had two posts on FA since then. the next post states that he removed the Stillen and installed his much awaited Crawford Plenum.

Guess what, loss HP and torque again. He goes on to say that Doug @ crawford advised that it may be ChrisG35C's "custom" Brullen exhaust retarding the ECU.

At last post (11/10/03) he was considering a TechnoSquare ECU mod. Nothing since then.

He's still got some work to do. I think we moved past what ever issues he is having or had.

Justin,
You may want to consult some of your techs over there. I've heard from two different Nissan tech types that the MAF and ECU adjust to air differences in a matter of seconds, thus no need for an ECU reset. If your techs are telling you something different, I'd love to hear the explanation and get to the bottom of that one.

By the way, are your Nismo CAIs in stock and ready to ship?

I know exactly how it all works.
The MAF reading is constantly changing and will always be accurate, no matter what you change elsewhere (intake, header, exhaust, cams, etc...) However, you're overall fuel ratio (it should be labeled A/F Alpha) and some other factors have to be learned over time to fully adapt and those are the factors that I'm referring to. As long as the MAF is in a good clean airstream, there will never be an issue with its readings, unless it's being maxed out or there is a leak in the system after the MAF sensor. Usually where stuff will get messed up is in the fuel delivery.

I've been one to say that a ecu reset won't help, but I also come from the older Nissan tuning, where the ECU's pretty much instantly started adapting to changes and fully changed very quickly. The new line of Nissan's ECU's have a lot more going on apparently and take much longer to adapt to changes, but I still feel that a reset is not necessary and it'll end up in the same place either way.

We do have the NISMO CAI's in stock right now.

Thanks!

More evidence of speculation. I'd love to see some real dyno's, none of this speculation.

Thanks Justin, but I thought there was only 3 different A/F maps. WOT, normal, and safe. Thus, the ECU really didn't "learn" any A/F settings, rather, it looked at coolant temp, throttle position, outside air temp, egt, etc. within milliseconds to determine which map to operate on in the present. In any case...are we agreeing? You're saying don't bother with the ECU reset, right?

I really don't understand why tampering with intake/exhaust would have anything to do with lean/rich. If you tamper with the air intake (or the exhaust for that matter) more air travels across the MAF, and the mass of the air in grams is communicated to the ECU so it can deliver the proper amount of fuel to the cylinder within the parameter of the map it is operating under. Why would sending more air across that sensor make the ECU deliver the same amount of fuel? Shouldn't it deliver MORE fuel because it is receiving MORE air?

Why aren't our cars all limping around when it's a high pressure, low humidity, cold day? More air mass is coming in in those situations also?

This is scaring me. Do I need to dyno my car with A/F readings everytime I tamper with the intake or exhaust? CAI, plenum, headers, cats, exhuast?

Damn it. I was concerned with the stories so I emailed Technosquare and promptly received this response:

"Currently we do not have a program for the 2004.5 G35 Coupe. It is a
different program from the Pre-2003.

You should get the ECU at the same time as teh Plenum, it will require more fuel to run on the top end. Once the ECU is available it will work with 5AT or 6MT.

Danny."

Well Brian I will take it off your hands if you don't want it. Just would have to pay you half now half in a month.

ill take it. how much?

Yes, we're agreeing.

The MAF is only part of the whole equation. The MAF tells the computer the mass of air coming into the motor and because of this, accounts for any changes in weather (pressure, temp, humidity), elevation, etc... The breathing efficiency of the motor may change with different mods though and will change the way the car has to react to X amount of incoming air. There really aren't specific maps for wot, part throttle, etc.. but rather parameters to go by.
RPM x load = fuel or
RPM x load = timing adjustment
etc....

Here's some examples that I found online of someone's maps, hopefully this helps show it better than I can explain in words...

I'm not willing to sell it just yet, I'll take my chances; I do know it's a quality piece of hardware, just whether it's worth the money is the question. In the event that I evaluate that it is not I will sell it.

Everything G35, why don't you expedite my order so I can put an end to this quicker.
