Let’s start off with something I would suggest pretty important, you can fully adjust the
Torque Actual and Torque Demand Maps live which Syvecs have mapped to copy as
stock presently. Syvecs did some testing increasing and reducing actual torque
and the difference was brilliant. (See link for logs below) Can make clutch
pressure apply more and less properly without having to increase touch
points which can make low down driving not nice. Can also adjust the slip
and shift point by changing the torque tables.
This made power go up and clutch temps to drop!

On other ECU’s available you can only increase the clutch Demand which is not the
right way of doing it for more clamping and why many have experienced
issues.
Features which are stand out for the GTR:
- Ability to use any throttle body for example if a big power vr38 wanted to
use some ls7 TB units.
- Fit any sensor to monitor and have trips from anything like crank case
pressure to damper positions (great for monitoring down force) etc
- Trips on important parameters like if oil temp gets too hot or oil
pressure drops at a set rpm
- Fuel pump control of both main and sub pumps
- Configurable Individual cylinder closed loop knock control, to suit any
cylinder modification with adjustments to frequency, windows for listening
and gains for each cylinder. Also in event of Severe knock full cylinder
shutdown.
- Monitor and trimming of 6 egts
- Built in data logging which can capture data at up to 1000hz and log for
over 8 hours
- Adjustable boost level, traction levels, launch levels and engine maps
through steering wheel buttons
- antitheft and valet modes
- pit lane limiter strategies
- ability to control any external items like having adjustable rear wing
linked to parameters like G force or exhaust valves etc
- fully adjustable traction control which links into lateral g or steering
angle from abs unit. Up to 8 different maps for level of control adjustable
on either steering wheel or external Pot.
- ability to change torque levels or demand levels sent to 4wd unit and tcm
Ecu for changing up shift and down shift points, Clutch pressures and diff
tightness.
- change torque reduction levels on shifts, very useful on big power gtrs as
the max amount on stock Ecu will not provide enough torque reduction on
shifts and overtime damage components
- change blip request amounts
- Run up to 7bar map sensors
- Change injector deadtimes based on voltage levels for proper control
- Change injector end angle to ensure injection point is proper suited. Very
important especially if using big injectors.
- 4 different pedal to throttle angle maps with multipliers for different
parameters like speed etc
- Fully adjustable closed loop boost control with launch level adjustments
and trims for turbo speed, act, ect, egt etc
- live tuning of any map
- Full VVT control
- Full Control over Fans
- super fast connection using rj45 Ethernet connection so ability for live
tuning anywhere in the world or even on Track if connected to wireless unit.
- Connect any race series dash or even one of our partners small can
adjustment /display units
- control up to 12 injectors so on big power vr38 engines ability to run
staged injection
- Wet and Dry nitrous control with ability to drive solenoids directly and
control n20 heaters via pressure monitoring
- control high or low impendence injectors
- view any input live with built in scope up to 1000hz
And much more which they are still working on.
