GTM 370Z 1000HP MAF CALIBRATIONN -ANOTHER MILE STONE
We would like to share a mile stone we've achieved regarding the stock ECU.
Over the last few months we've been working on developing a way to overcome
one of the limitations of the stock ECU when it comes to making big power.
While Uprev enables the aftermarket to rewrite the stock ECU in the
370Z/G37, there have been a few hurdles to jump when pushing the envelope
over 600whp. Since day one, we always kept in mind that people will only
want more power. In anticipation, we chose to use 3" MAF piping in all of
our turbo kits and the GTM Stage 2 Supercharger Kit. Doing that gives us more
headroom when it comes to MAF Voltage. It's a mechanical calibration that
allows us to get the factory MAF to read more airflow. Even at 600whp, the
MAF voltage is getting up to 4.9 to 4.95 Volts. While this is still below
the 5 Volt limit, it does not give us any headroom to compensate for
changing atmospheric conditions (such as a cold morning). The next step was
to find an aftermarket MAF sensor that can replace the factory Nissan unit
with the same physical dimensions and connector. Of course, that was the
easy part. The challenging part is to produce a good calibration that
contains a linear MAF curve so we can get the best resolution and still
plenty of headroom for more horsepower while retaining
factory drivability. This development translates into having a 1000hp car
that starts up every time and can be driven normally on the street.
Ultimately, this has greatly expanded the capabilities of the factory ECU
to the level of performance commonly relegated to a standalone EMS. While
some standalone EMS options may have some additional features that set it
apart, we've really narrowed the gap here.
To close the gap altogether, we are working on developing a system that
will enable us to retard ignition timing in response to knock as well as Boost cut. Once that is developed,
there will be no reason for a standalone EMS in this platform.

Forced Induction - Supercharger vs. Turbo Charger
This video was made to describe in moderate detail the differences between
Superchargers and turbo Chargers, as well as describing the
components, advantages, and disadvantages to each. Complementing the
speaking track is a slideshow of related pictures and videos. I hope this
video helps some of you curious up and coming mechanics to better
understand methods of forced induction. Please comment maturely, and

Pride Performance GTM Supercharged 350z
An example of the work we do here at Pride Performance. Our customer came
to us in search of turning his 2007 Nissan 350z into an exciting car to
drive. His main concerns were drivability, reliablity and the use of the
stock clutch / flywheel. The end result: A 400+ whp daily drivable/reliable
