After many months of development EcuTek are proud to announce the release of RaceROM Phase 2 for 370Z. It's been two years since the initial release of our 370Z software and there has been a huge amount of work put in by the development and testing team to create this class leading product.
Check out the results we achieved with the Stillen Supercharged 370Z plus the RaceROM tuned monster 800bhp turbo charged D1 Drift car here

Map switching for the 370Z provides 4 separate customisable tuning modes, which can be changed on-the-fly by the driver using the cruise control switchgear.
These modes can be customised to provide bespoke settings such as:
Mode #1 Economy Mode
Tuned to provide the best fuel economy but with reduced performance.
Mode #2 Road Mode
Tuned to provide the best performance for regular fuel quality.
Mode #3 Race Mode
Tuned to provide the best power using high octane race fuel at the track.
Mode #4 Ethanol Fuel Mode
Tuned to run on Ethanol based fuels
Map Switching also works with other RaceROM features such as Launch Control, Flat-foot Shifting or Speed Density, enabling them to be switched on and off depending on the mode selected.
|
|
Flat-foot Shifting allows you to keep your foot flat on the accelerator while changing gears to minimise your gear change time and to maintain engine speed for when the next gear is engaged.
By reducing the engine torque and controlling the air fuel ratio during gearshifts, the engine, clutch and drivetrain are not unnecessarily stressed. This is very important on forced induction vehicles where the power output is substantially higher.
|
|
The Speed Density (SD) feature changes the way the engine load is calculated. When SD mode is activated, the ECU will disregard the MAF sensor reading and will instead calculate mass airflow based on engine speed, manifold pressure, variable valve event lift (VVEL) and air temperature. This feature can be useful in the following conditions:
- Extra large MAF sensor intakes have been fitted causing low air speed and poor air speed stability
- The MAF sensor reading suffers from air turbulence from the compressor wheel (turbo and supercharger models)
- If an external blow off valve has been fitted (turbo models)
- The MAF sensor reading hits 5 volts at high RPM
In addition, the Hybrid Speed Density feature offers a combined MAF and SD configuration, the transition from MAF to SD (or SD to MAF) can be calibrated against a range of activation thresholds like engine speed, mass air flow or manifold pressure. The Speed Density feature can be enabled in any of the map switch modes.

The RaceROM Controller is a driver-adjustable input to the Custom Maps system. The driver can select a value using the cruise control buttons and it is displayed on the oil temp gauge. The tuner can create a custom map to adjust any of the engine parameters based on the driver’s input. This could be used on a forced induction car, for example, to select a desired level of boost. It can also be used by the tuner to provide a certain amount of live tunability.
|
|
This feature allows per-gear rev limits to be configured. It could be used to improve 0-60 times by allowing a higher 2nd gear limit to just hit 60 mph / 100 km/h in 2nd, whilst preserving the lower rev limit in other gears.
|
|
RaceROM Custom Maps allow the tuner to modify the behaviour of the factory ECU by inserting additional maps into the ECU's normal calculations for parameters such as ignition timing, fuel, boost & VVT. It also allows re-purposing of inputs and outputs to measure custom sensors or solenoids not featured on the standard vehicle (Flex-Fuel, EGT, Oil or Fuel Pressure for example).
For more information on these powerful and unique features, see the dedicated Custom Maps Manual. See below a few examples of what is possible using Custom Maps.
|
|
The launch RPM is adjustable from the cruise control switchgear and can be enabled for any of the four map switch modes. Also included is an ignition retard traction control feature that can help reduce wheel spin after the launch.
|
|
Using Custom Maps we can create a fully adjustable Traction Control system that can simply be adjusted using the cruise control switch gear on the steering wheel. Too much or too little wheelspin for the current conditions? Simply fine tune the calibration in an instant. The current Traction Control level can be displayed on the oil temp gauge and the wheel slip amount can also be shown.
This powerful feature is a must on any forced induction models and Custom Maps can even use steering wheel angle and g-sensors for the Traction Control calibration.
|
|
RaceROM Custom Maps can offer a wastegate solenoid driven boost control on forced induction models. This can be a basic open loop control setup or a more sophisticated closed loop system with proportional and integral control. Additional compensations for gear, altitude and temperature can also be added. This output duty cycle control can be used on supercharged models to recirculate or vent inlet manifold pressure during part load condition when undersized drives are used. The boost pressure or wastegate duty can also be displayed on the oil temp gauge.
|
|
The 370Z can now be accurately tuned for any ethanol content ratio making it a safe and reliable flex-fuel setup. Like with the FR-S and GT-R setups, Custom Maps offers detailed ignition and fuel control for any given ratio and this can be linked to boost control on turbo models. There are already a few ‘plug and play’ kits that make flex fuel upgrades very quick and easy. The current Ethanol content ratio can also be displayed on the oil temp gauge.
|
|
The 370Z does not offer a full load closed loop fuelling control like the GT-R. Using Custom Maps we can set up a closed loop injector volume adjustment for a profiled target AFR. The AFR target feedback can come from the factory AF sensors or even better, import true wideband sensors through the rear O2 sensor to set up an accurate closed loop fuelling control. With an AFR fail-safe configured as well, this feature provides unparalleled engine safety for forced induction models.
|
|
Fail-safe maps can be created to protect the engine should the fuelling run lean at high RPM, high boost or high speed. Additional protection can be added for air, coolant and oil temperature exceeding certain thresholds.
|
|
This feature allows the tuner to repurpose the oil temp gauge to display a different parameter such as AFR or fuel Ethanol content
