Seems pretty good. Cobb is 200 for AWD, only 160 for RWD. http://www.cobbtuning.com/info/?id=2965
if you get a guy who takes interest in your car & adjusts everything to be safe all around, & then tweeks a bit for a good powerful tune without pushing it to much, & get good drivability safely out of it as an end result, I'd expect to spend up to $500.. this will include a dyno session. might want to do a baseline dyno run before the supercharger install too which could be $75-$125 depending on what they charge, I found a guy that dyno'd me & charged me $75 but most are a bit more. talk to the tuner & if you get the feeling of trusting him then go with what he suggests for the most part, the more he charges the more he'll do most times hopefully, just don't let him talk you into more than you want to do either. nice to have a good relationship with a tuner...

~Definition of "Tuning" from an Internet search ~
-Tuning is the process of selecting the appropriate genetic operators and their respective parameters to suit a problem.
-The process of adjusting a radio circuit so that it resonates at the desired frequency.
-The Process of Establishing the Desired Frequency of a System
-The process of adjusting all of the working parts to their optimum positions.
-(music) calibrating something (an instrument or electronic circuit) to a standard frequency
As you can see, tuning is basically making an adjustment on something to get it working properly. This certainly applies to our philosophy of ECU tuning.
Automotive manufacturers design and tune their vehicles for general public usage.
To achieve better emissions and performance in today's automobile, the ECU is programmed to function in correlation with the stock condition and specification of the vehicle. Nowadays, factory tuning is done very well in order to get peak performance from the vehicle as its driven off the showroom floor.
However, when you start making modifications with performance parts, the ECU will continue to function as though the vehicle is running stock unless you tell it differently. Common problems are that the vehicle runs too lean/too rich at certain points or even an entire range of RPMs, or there is detonation under certain conditions.
TECHNOSQUARE ECU tuning provides solutions to these problems by making the necessary adjustments to the program and map data. In other words, we tell the ECU how to work with the performance parts installed.
As a result, in many cases, the vehicle gains torque and power from our tuning, however, in some cases, it may lose some in order to gain reliability. This is why when customers ask us "How much gain?" our answer is "We don't know".
Our objective of tuning is to get your engine running well and staying healthy for as long as possible.
The Power is not everything.
The Number is not everything.

[/FONT][/FONT]
After exhaustive research and development on both the hardware and software, Technosquare is offering ECU flash reprogramming of flash type Nissan ECUs for racing applications and performance enthusiasts.
Current Nissan ECUs come with VERY sophisticated engine control functions, such as a constant O2 sensor feed back system and torque management by an electronic throttle control system. In another words, the ECU has complete control of the engine, not you. When it comes to performance modification and driving, these systems will get in your way, as the factory ECU is set to work best with the stock configuration of the vehicle and ordinary drivers.
When you start modifying your Nissan, you will find it very difficult to gain output by just adding performance parts. In some cases, you even lose some power and torque. Since the ECU is unable to automatically detect the modifications you made to your engine, it will still try to work within the parameters set for stock condition.
The Technosquare ECU flash changes these parameters to the specification of the performance parts installed, so the ECU knows how to behave under modified configuration and fully utilize the intended capability of those new parts.
The Technosquare ECU flash also changes the electronic throttle control setting.
Even if you push the gas pedal to floor, it doesn't mean your throttle is opening 100%.
Nissan sets the throttle characteristic for various particulars, such as torque management for drivability, or Venturi effect for faster induction and more. This is fine for the average Joe content to run his car stock, but a lot of enthusiastic drivers find it very annoying.
Technosquare puts you in control of the throttle (but still maintaining VDC or TRC features), so when you step on the gas pedal all the way, the throttle opens all the way and stays open.
As the result, engine can utilize higher flow intake and exhaust system improving (optimizing ?) throttle response.
This feature is exclusively available ONLY from Technosquare.
G35 TECHNOS ECU Introduction The long awaited ECU has finally become available. Introducing G35 TECHNOS ECU upgrade. After hundreds of hours of R&D and numerous Dyno pulls, we have successfully developed this ECU, as part of a performance upgrade.

FEATURES:
REV limiter modification
A 7100 RPM (stock 6600 RPM) rev limit is set to take advantage of top end horsepower.
The stock rev limit was set way too low. Some of you may be having the problem of hitting the fuel cut at hard acceleration. We found this very annoying as we increased power at the higher rpm range. Hitting the rev limiter too often, could actually damage the engine since it is achieved by cutting fuel. By adding an extra 500 rpm, we can avoid hitting the rev limiter while protecting the motor.
Speed Limiter Removal
The speed limiter is removed. The stock limiter was set at 250Km/h (156 MPH), so for all practical purposes, we could have left it alone. But we decided to remove it, just in case someone feels the need to go beyond that.
Ignition Timing Map Adjusted
There wasn’t much room for improvement at the bottom end since the ECU retards a lot of timing by using a feed back system in stock trim. So, we have added more timing at the higher end to take additional advantage of higher-octane gasoline. This aids in improving torque from 3000 rpm and up.
Fuel Map Adjusted
Stock fuel was set to detune the top end horsepower. We discovered that the car runs extremely rich after 5000 rpm. Air to Fuel ratio (A/F) of 10.5 was found right before the stock rev limiter kicks in. Cleary, Nissan was trying to detune the power output at higher rpm to discourage the driver from hitting the rev limiter. For the performance enthusiasts, however, this is unsatisfactory, so we set the A/F to 12.5 all the way to redline to provide adequate power gain while still maintaining a safe margin.
Drive By Wire Adjustment
Throught our testing we found, the drive by wire system was program to never fully open (throttle flap) when you smash the accelerator pedal. In fact, it actually closes the closer you get to the rev limiter, by as much as 20%. This restricts air into the motor and causes HP and torque numbers to go down. We have remapped this setup so when you go wide open throttle, the throttle flap fully opens and STAYS open, increasing HP and torque.
Testing was done on a stock G35 6Spd

Adding to above modifications, a few other adjustments were made to other maps to enhance the feedback function which improves power, torque and drivability. The resulting achievement is a remarkable improvement in driving feel, which is more than what numbers alone can tell you. We are very satisfied with the results and are proud to release our TECHNOS ECU for this tuning-challenged ECU, blowing the lid off what was thought to be an automobile already running pretty near its maximum capability.

Changed air intake system
One of the major problems on this car was a feedback system that compensates for modifications. The oxygen sensors detects fuel mixture and will tell the ECU to richen up or lean out the mixture. This correction factor was way too wide, so some performance components upgrades (intake, exhaust) would actually result in a loss of HP below stock!
We adjusted the correction factor to reduce that compensation reaction. Our tests showed consistent power and torque improvement following installation of an intake system.
We will be conducting additional testing on various intake and exhaust systems for the compatibility of our ECU. Although we anticipate a dramatic improvement per component upgrades, some may require custom tuning to take full advantage of their performance.

This shop was recommended to me by a guy with a turboed Z. That thing looked and sounded nasyt...lol. He is about 25 miles away. There is also a shop up in Gaithersburg, not too far from Bill I think.
A flash-tune is not the only way you can tune... you can have a Unichip, UTEC, Haltech, etc as either a piggy-back that alters what's being sent from the ECU to the injectors, spark ignition, etc... and there's stand-alones (Haltech and others) which act as an independant ECU.
As for price... tuning is definitely $125-$225 / hour depending on where you go. Some places tune like crazy so they can afford to have cheaper prices because they know that's what will occupy a majority of their time. Some tuners are also performance-oriented mechanics who tune on the side. I've had plain old base-line dynos for as little as $50 for 3 pulls, and I've scheduled tuning for $125/hour and told about 2-3 hours.

Are there any chips for the 35? I see one for a 45 at unichip http://www.unichip.us/search_result...es_make=Infiniti&dhtmlgoodies_model=453055243
does anyone know if there is a way to change the shift points in our FX35 or if it's really needed. I don't remember for sure who said they were needing to shift manually 'cause auto was doing it too slowly once they were supercharged. Frankiago... did I hear that from you? I'm guessing here cause i think you had the LMS charger installed at one point.
Anyone from Vancouver who knows a good tuner in Vancouver area for our FX?
