The dealership only wants to do a Consult, and it always comes up fine. What I really want to know is, does this "irregular coughing" of exhaust signify a bigger problem that the dealerships just aren't capable of handling right now?
Thanks again for asking this question for me.

Nice info......so did nissan get you a loaner car or are you out a car till you get your tranny fixed???? And also are you the same person that was told by the nissan dealer they were flying reps out to look at your car and they never showed and it was all just bull ****? Then you car had like 110 miles more on it than when you left it there? If so did you relay this on to this new contact?
My only question to him would be on the g35c regarding hp compared to the 350z? i heard that they are the same engines and that Infiniti just lowered the hp on paper to make the 350z the more sporty car.
good luck with getting yours fixed and im sorry that you have to be the ginney pig. Hope you get a quick fix soon.

Yes im the same person that was told they were coming 2 weeks ago....and since i was told that....this guy im talking to actually made it happen....so i guess they didn't lie because it end up happing weeks later.
Yes he knows all about what happened...thats how im talking to him in the first place...just call it damage control...and NNA.....HAS been GREAT....SO FAR.
Yes i gotta loaner....chevey malibu
I'll ask about the G35 and the Z...he talked about if briefly...but I personally didnt care about the G35.

Thanks, Boomer

To get best out of stock setup (320) change the timing, air/fuel mapping and stuff in the programing...and also said something about makeing the stock mass air flow system go from 20 something to 30 something....That are the future fatory mods for the Z unless they decide to change the motor by going in it...the future stuff isnt set...
He definitly gave me the impression that there is alot more power in tuning the ECU...actually he called it ECM
He said that is what nissan has done in the past to increase power in the altimas and maximas
Obiviosly I asked him to do it on my car now....he chuckled ...I keep putting a bird in his ear that we are dying for more hp and that whoever makes mods that produce gains has alot of money to make
![Big Grin](https://my350z.com/forum/images/smilies/biggrin.gif)
he remarked Nismo is coming....Geezz
He also hinted.....saying does 350z stand for the engine size (liters) or the future HP rating....he chuckled again.

Hey Ab......... A good thing to do if you can is tape record your next conversation so you can recall everthing that he says.......not being a smart *** but this will help with all the info. this guy is throwing at you, i know it is hard to absorb everthing your being told. Just an idea?

I can record conversations with my phone...thanks for pointing it out....I hope he calls on my home line tomarrow...I'll try to record it next time.
Darn didnt think of it lastnight...my caller ID says its from a Pay phone one time and private this time...weird???
I'll be talking to him a couple more times till my car gets fixed. I met him once in person...very smart and nice guy.

I know in a lot of exhaust systems, backpressure can be an enemy and a friend. I wonder if modifying the cats on the car will help with power.....I know there are ways to trick ecu's on other cars into thinking the cats are still on the car when in reality they have been removed. This could produce some significant hp gains in a car that has been "detuned." Anyone following what I am saying?

Abyss--
Let me know what ends up happening with mods. I'm already talking to Nismo, trying to find out when they'll have a turbo charger ready to go, and of course other stuff.
No such thing as too much power.

I posted earlier about getting up to 320hp, please ask him how
they might effect durability and drivability. I plan to keep this car for 8-10 years and so do a bunch of other members on this forum. I know they will be as interested as I am. THX, ABYSS. You've taken on a lot here on this topic and the rest of us appreciate you doing it.

He said that some of the Nismo parts will state FOR OFF ROAD USE ONLY....Meaning it will not be covered under warranty...
Aren't OEM ECU running rich already
Hopefully Nissan will offer a re-flash service for the ECMs through their dealers. If we have to purchase a new ECM, it could be very costly.
Of course, I need to master the 287hp I have before I take on more!

Questions for the mystery man:
Variable Cam Timing Questions:
What is the signal and range for for the Variable Cam drive? Analog or Digital? etc...
What mechanism actuates the cam timing? Servo driven planetary gear? Clutch mechanism? what?
What is the range of motion of the cam timing drive? How many degrees can it advance or retard?
ECU questions:
What inputs does the ECU look @ to determine the speed limiter?
What inputs does the ECU look @ to determine RPM limiter?
What inputs does the ECU look @ to determine Ignition timing?
Engine Questions:
What's the weight of the flywheel?
Forged or Cast Pistons?
Interference design head? Meaning is it possible for the valves to make contact w/ the pistons.
Injectors high or low impedence?
Are the crank and cam ignition triggers rising or falling hall effect sensors?
I'm going to be piggybacking a standalone ecu over the stock ecu. Allowing the stock ecu to run all the trivial bits of the car. While the standalone handles the engine management. Should be able to see the motors true potential unharnessed from the factory ecu. Expecting delivery early Novemeber, should have some result by the end of Novemebr. Info from an inside source would help things move along @ a brisk pace.

Please ask him if the G35 coupe has the carbon-fiber drive shaft. If it does not, could you ask him how much HP loss is there in the G35 to get to the wheels.
Thx.

Great post! I look forward to reading up on all the responses. Looks like there's plenty of room for serious hp gains. Keep up the great work. Thanks for sharing your insights.
RE: Bose - It just so happens I spoke with a Bose rep who just got back from a Cali meeting with NNA about the replacement amp. They were discussing the logistics for getting them out to all the dealers. I was told NNA will only be sending out notifications to all those who have registered a complaint/problem regarding the Bose system with Nissan Consumer Affairs sometime in November. Eluding to the fact that, if you don't register a complaint, Nissan will assume you're happy with the system. Make sure you let them know, or you may be left out of the loop in getting a fix. I would assume the amps are already being replaced on the factory assembly line, since they are manufactured on that side of the world. They delay is logistics at this point.

I GOT MY CAR BACK!!!!!
THANKS NISSAN FOR THE EXTREMELY FAST SERVICE!!!!!!
Brand new tranny installed and TROUBLE FREE....
clutch fixed
brand new tranny runs perfect.
new pedal sensor installed.
Total time without car....3 days
Now if they can finally get my value stem caps and bose fix... my car will be perfect.
Well I just washed her and waxed her....gonna go for a spin.....shifts are smooth and redlining is no problem...now where are those f bodies at??? JUST KIDDING

What is your source for the ECU? I'm sure we would all be interested in an ECU mod.
