GT-R RaceROM Phase 7 – New Traction control, Launch control, 12 injector updates and more…
Ecutek RaceROM Phase 7 is here
Linney Tuning and the team at EcuTek are delighted to announce the release of Nissan GT-R RaceROM Phase 7, available for all GT-R models.
Ten years in the making, Phase 7 puts the EcuTek GT-R platform at the cutting edge of what’s possible with the stock ECU. Read on to see all the great features in this new release.
RaceROM Phase 7 update has the following feature updates
New Advanced Traction control system
Traction Control can play a vital role in the handling and dynamics of your GT-R. The OEM Nissan system is simply not suitable for higher than 600hp power and high level of wheel slip, it can be too intrusive harsh closing throttles or throwing an awd clutch overheat limp. Running in VDC-R mode can be more effective with stability control but can still suffer from the delayed response and throttles closing at the worst moments, sometimes dangerously so if in an overtaking situation. The driver is then faced with a 3rd option of turning the VDC off raising further the threshold for limp/throttle close but at the expense/risk of excessive wheel slip in many cases very high wheel slip causing tire wear, damage to drivetrain/FWD clutches.
The main principle behind slip based traction control is that a tyre provides the best load transfer when experiencing a small amount of slip. the simple way to look at it, is the ideal amount of slip is the one that gives the best result. As a simple guide for maximum straight-line acceleration in dry conditions, 10% slip is somewhere close to what we want, and for hard cornering, it’s closer to 2% and will vary between those depending on how hard the car is cornering, the surface, the tyre type etc.

Custom maps – adjustable user control
custom map 3 is Traction control wheel slip…. minimum on slider allows more slip, i.e dry / straight line …. maximum allows less slip for wet / corners
custom map 4 is traction proportional ….The Slip Error is multiplied by this gain to calculate the Traction Control System Torque Reduction. increase gain from min to max you would get increase the torque reduction for any given Slip Error, lower values of TC Integral Sum mean that TC Torque Reduction is reduced, meaning less traction control interference. Gain is configurable against gear position.
custom map 5 is Traction control integral gain…..Integral correction is added to the proportional correction to give the overall Torque Reduction. The gain value is multiplied by the slip error to give an integral step value, which is added to the existing value of TC Integral Sum. The result is that the integral correction can ramp down and up to try and keep the slip closer to target.

Contact us now to arrange time to upgrade to Phase 7. If you have Bluetooth EVi or ProEcu cables we can schedule an appointment to start calibrating your GT-R remotely, or we can also set up in person.
To upgrade to Phase 7 if you are a returning client with the same spec GT-R we tuned previously the price is £300 / $400. Update price is the same if you have an older Phase 1 or 5.2 cal file as it’s a brand new fresh ROM file from scratch. New Clients without Ecutek will need to purchase from us the EcuTeK Bluetooth EVI and licences. Linney Tuning Tuning products
