replaced the factory ECU (engine Control Unit, or main computer)
with an AEM
1311 EMS (Engine Management System). The 1311 is specifically
for the 3000GT VR4. The AEM allows for complete control (via your
laptop) of all engine systems.
with this I included a new AEM
wideband O2 system (dual channel UEGO), AEM IAT and MAP sensor
(3.5bar). The widebanc O2 allows for better fine tuning than the
narrow band factory O2 sensors when in closed loop operations.
MAP sensor switched me from factory MAF control (Mass Air Flow)
to a Speed Density system of fuel/air management. Speed density
has advantages one of which is the engine will continue to run if
a turbo hose or intercooler line blows.
Serial gauges I can choose any one of 19 parameters to display
live at the touch of the button. Very handy (see gauge image below
or choose Interior Photos for actual pctures of installed serial
(Horsepower) - after several hours on the dyno in October I had
to halt further tuning above 18psi. The current clutch wouldn't
hold past 480HP (AWHP). New clutch (stage II+) and lightweight flywheel
install sometime soon and then further tuning above and beyond 18psi!
are some of my fuel map images, timing, and calibration settings.
Included are the actual calibration files (only usable with AEM
Pro Software). These are tuned specifically for my car only.
