How do you tune a Z-car?

nobody is putting his dirty hands on my futur 370Z apart from NOVIDEM...

he is THE specialist tuner for 350Z in Europe (supercharger kit, free exhaust,...)

I can vouch for Cobb. I used to drive a 2005 WRX (which I had to sell unfortuntately) and I bought the AccessPORT to accomodate my modifications, commonly known as Stage 2 (turboback exhaust + AP) in WRX.

It is of good quality and functionality, especially, with the new 2nd version of AP (it used to be a size of a huge brick). You can bring in your car to a professional tuner authorized by Cobb (simply means they tune using the Cobb AP). They upload the custom map in to the ECU via AP.

Another feature I love about AP is you can store multiple maps; load and switch in to your ECU, whenever you need to.

It's quite a useful, very convinient device. Cobb offers "off-the-shelf" maps which is very conservative. But, at least, once you install the modifications to your car (within the parameters of the description of Cobb setup), you can take it for a spin safely, for the glimpse of what is to come after the custom tune.

If you want THE BEST results from a tune, nothing can beat a dyno tune. These hand held products are a great idea but they have been pre-tuned with estimated changes according to your mods.

UpRev Osiris is an amazing software that should be released for the VQ37VHR very shortly.

The Cobb AP has this feature also. Sure it comes with preprogrammed tunes but you can also take it to any dyno shop that has AP software and get a custome tune for your car. What most Suby guys do is run the stage 2 tune from cobb and then later take it to a dyno shop to get a custom stage 2 tune done. So the this particular hand held has the best of both worlds. For those who don't want to fuss you can just run the predone tune from Cobb and for those with other mods or looking for more power you can use your Cobb AP to get a custom tune. Also people forget that the cobb AP is more than just a tune, it has many different features that most car guys would like to have.

dang it skaterbasist lol you beat me to saying about uprev. lol but honestly uprev will give you the best bang for the buck at 700$. Just recently they got up the vqhr support and a stock 07 nismo made 15hp (not sure it whp). Which is amazing ill say. so i wonder how much i can make with test pipes and just a cat back

doc

wow RCZ,

i really am a noob at the whole mod thing. excellent post.

^^^ It just takes experience. The more time you take to research this stuff, the more you will learn.

Anyway, I am not a fan of N/A. If you guys want real power, go F/I. There's nothing like feeling the onset of full boost. You go from to after mashing the pedal.

BUT... Not everybody can void a warranty and not worry.

If you decide to tune a car on a chassis dyno make it one that will load the engine. Otherwise you are tuning in a very narrow load range.

Cobb should have an Access port out for it soon.

What's available for the person that wants to tune everything on their own? Is there some software and a diagnostics port cable of some sort?

I know UniChip is coming out with a piggy back that has two settings one for everyday driving and then a setting for track days. You can also DL updates if you install aftermarket exhaust and what not.. Looks pretty good to me not sure what you all think tho. If anyone has used this let me know how it worked out please..

Technosquare INC just finished the initial tune of a 370z prototype.

results are pretty good. i want to wait a few more days and have them run some more tests until the program has finalized before i post dyno sheet... the only modifications this car has is a set of JWT pop chargers. peak gain of just around 10 rwhp. with nearly 15-17+ in the midrange for both torque and hp.

initial release of the program is very soon.. Technosquare also has high flow cats, a stillen exhaust, and other modifications that they are using for dyno testing and tuning variability..

stay tuned.. heh..
