It starts to max out around 9pis, but ANY ECU reflash system should have the ability to re-scale the MAF for a larger tube diameter or a GM sensor.

I'm sure it will be a non issue.

Jared, to what gm/s does these 9psi translates? Thanks

 

Yes, I mentioned tha earlier. I think this platform will be better suited to NA applications, unless there is an option for a MAP sensor input.

 

So what is the progress now?

 

Wow, sorry Dolva, I missed that response.
I'm not sure what the max flow is off the top of my head, but I can find out next week when I get the turbo back for one of our customer cars that is running close to the limit.

A custom tuned reflash is a great way to tune a turbo Z (if you know how the ECU works and how to modify the code). We've done a couple at our shop already w/ NO OTHER engine management whatsoever and they run like they came from the factory FI.
You don't have to run speed density to run boost. WRXes for instance only use the MAP sensor for boost control. Ignition and fuel are still based off of the MAF. Even the old 300ZTTs use a MAF to measure load.

MAF sensors also take environmental variables into account by design where as w/ a speed density system you have to have compensations for things like intake temp and atmospheric pressure which means MAF based systems tend to run better under varied conditions. There’s a reason that virtually all manufacturers use MAF based systems now.

Anyone using the Z32 MAF ~550bhp or even a late model Ford Lightning MAF ~800bhp

 

Im using the Lightning MAF housing now. Dynos to come.

Later

I'm interested

 

i like the sound of this COBB

WTF, didn't you see the first page of this thread? The release from Cobb is dated 9/1/06.

 

so what is the update on this.

 

no eta as of yet - look for it in the first half of 2007

 

First quarter turns into first half...I'm giving up.

 

that's the nature of electronic parts, or any parts that require R&D - especially ones that involve the ecu of a car.

Sony cannot even deliver enough PS3's - and that is Sony.

Maybe it will be first quarter - maybe later, but when it does come out, I am sure it will have been worth it based on my past experience with the unit on the Subaru's

 

What's the little hardware device for?

It looks like the system also requires a notebook, why not just put all the code on the notebook and go with that?

Hmm... maybe the little box is just a map switcher... easier to keep it from flying off the front seat than a notebook.

 

For a Scoobie, the little device holds up to 6 MAPS I believe, and once you performed the first install where the Cobb device installs its "hooks" into the ECU then you can switch MAPS "on the fly" (well almost, as it takes about 20 seconds). My friend has one for this STi. He'll load the economy MAP to get decent gas mileage to/from the track then load his track MAP while in the paddock to wring all he can out of his STi out on the track.

He would download MAPS from Cobb's website then he went to a Scoobie tuner who had the Cobb tuner s/w setup who could write/create Cobb MAPS for this device and got three custom tunes (one for Spring, Summer and Fall). In addition to the Tuner uploading them to his device, they also burned them on CD for his to have a backup copy.

I am waiting to see if the Cobb device for 350Z's will be only for NA applications or also support FI.

 

Thanks for the explanation!

I wondered how they "hooked" the device to a single car. They must install a key in an unused area of the ECU's memory.
