370Z Driving with the Ferrari's.
While sound asleep at 8 AM, I got a call that in 12 minutes, twenty
Ferraris were heading to the top of the mountain then to Stinson Beach.
Although I'd stayed up till 3 AM, I decided I 'd get dressed and drive
along for half an hour. I still need to go to work at 11 AM. I catch a few
in the group, and while they pull off to look at their directions I assure
them I know the way. They follow. Well, apparently my info was not perfect
but I had a blast. Sorry for the bad info to you Ferrari guys. At least it
was a good drive, not like I placed you in stop and go freeway traffic.

GTM 370Z TWIN TURBO WITH TRACTION CONTROL THE ULTIMATE DRIVING MACHINE " NOT A BMW "
We received a phone call from AUBREY inquiring about our GTM 500HP PACKAGE,
customer at that point have not even purchased the car yet, So he went and
got him self a new 2010 370Z 40th anniversary edition and had it
transported to us from Virginia , The car was 100% stock with less 200
miles. Customer's goal was 500 to 550 RWHP and that was the beginning of a
Here is the list of the upgrades
GTM Stage 1 Turn-Key Twin turbo System
GTM 3" turbo Cat-back Exhaust
GTM 3" Downpipes w/ External waste gates
GTM Diff cooler
GTM Competetion oil cooler
GTM Stainless Braided Clutch line
GTM Stainless Braided Brake lines
GTM ECU reflash via Osiris uprev
OS Giken Twin Plate Dampened clutch/flywheel kit
HKS EVC6 Boost Controller
STOPTECK Drilled rotors
GTM RACELOGIC PNP TRACTION CONTROL
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.
