Default ECU Tuning

I was just wondering if, for my 2008 350z, could I get a reflash, or some way of getting more power out of this car? I was just reading an article about a company, Technosquare, and they used a 2007 350z, did some pulls, and tuned the ecu to give out about 22 more horspower, and about 50 ft-torque. I have dual intakes installed on my car, and I am looking at getting some more gains. Any input would be appreciated.

Check Technosquare and see if they do the VQ35HR ECU.

yeah i tried going to their site but seems their server is down?? the article i was reading was on the 2007 350z, which is obviously the HR engine. Im in the Richmond area, and posted in the regional forum as well, but can't seem to find a reputable place nearby that would possibly do a Technosquare flash.

Dave @ Function:TUNED can do a full dyno tune using our Osiris software. He's a little over 2 hours away. None of the basic prebuilt flashes have done much on the HR cars so far, dyno tune is needed to much any real gains out of them.

22 Horsepower gain with ECU reflashing (or any sort of tuning) would only be possible if the car was running like utter crap before you started tuning. Honestly with a totally stock Nismo Edition we gained 8whp peak, and somewhere near 10 under the curve. Now if you have some mods on your car that would throw the stock ECU out of whack, say test pipes and headers, then you'd be running so lean that a tune might net you large gains, and help save your motor.

thanks for the input. Yes I am aware of Function:Tuned, I hear they're great. All I have is the Fujita Intakes that I feel on the butt dyno has some more pull, in the mid to upper rpm ranges. Would that throw the ECU out of wack slightly? Just tryin to look at any possible upgrades to get good gains.

Well this is the thing. Tuning doesn't make power. The mechanical parts you have are what make power. All tuning does is control those parts, so you can make them run more efficiently. You can obviously run a tune on the ragged edge of those parts or you can step back a notch and make it run safer.

Some cars from the factory are running unsafe. Hence the need for warranties. The more sophisticated a car becomes, the more control the ECU needs to help keep the power levels consumers want, while placating the manufacturers need for low warranty issues. The general idea of the stock tune is to make sure the motor doesn't purposefully end it's life because of a little detonation or a small batch of bad fuel. Bad part is that the ECU itself can only do so much adjustment, even the factory motor my be far enough out of whack that it runs lean or rich, too much or too little timing, any number of things.

Thats where a tune comes into play. Even on some factory vehicles a qualified tuner with a dyno can get reasonable gains in power just by helping the car run more efficiently and safer. Start adding mods that change the air flow capabilities of the motor and that becomes more true.

Base tunes became real popular on cars like the Subaru WRX/STi and Mitsubishi EVO because there was so much safety involved with the factory tune, that just by pushing timing and changing some basic parameters you could make 20-25 wheel horsepower. Thats going to be believable on a car that comes from the factory with forced induction, and those are generally quoted as peak numbers leaving nothing said for under the curve power. It doesn't work that way for a car that is naturally aspirated though. Add in the fact that your car may be running lean as it sits and that base tune may be telling your car to run even leaner... welcome to disaster. A Dyno Tune or at the very least a product that is adjustable by design and can be verified after the tune is done are going to be the safer more productive routes. You'll save money in the long run, and you'll be able to enjoy the car more.

A tune is a good idea at any stage of modifications. Pick one that can be adjusted, and can grow with your needs. Especially if you plan on ending up forced induction and don't want to have to buy it twice.
