RaceROM Updates

Turn launch control all the way up to 11

Our newly updated Boost Off The Line strategy gives great response, it has closed loop everything, it works well out of the box but remains easy to tune for big turbo installations. Mappable Launch RPM Overshoot to get big turbos on boost Closed loop ignition control to keep boost on target Ignition limits to prevent RPM from bogging Throttle compensation for retard Throttle integral correction to keep RPM on target 3D randomised fuel cut for maximum effort cars No more OEM fuel cut interference You can still live adjust the launch control RPM and boost with your iPhone or Android device using ECU Connect, or by using the cruise control switchgear. The advanced control “just works” to keep your launch control on target.

Custom Sensor Inputs

You no longer need to define third party sensors using custom maps, as we have added purpose made sensor definitions for commonly used sensors such as fuel pressure or coolant pressure. These custom sensors have their own dedicated live data parameters which can be logged, used in Custom Maps, trigger a failsafe condition or they can be used by our new compensation maps. Boost sensor input problems have been addressed by using one OEM boost sensor to supply the ECU with both boost sensor input, leaving one free to be re-purposed for custom sensor inputs.

Injector characterization and fuel correction

To support the latest trends in large injectors we have added maps for injector latency and low pulse width compensation. OEM strategies provide only a linear latency which is correct over a narrow voltage range. Now you can use plug and play data from your injector supplier to correct properly for the full range of battery voltage. Using a third party fuel pressure sensor added via our Custom Sensor Inputs you can also calibrate injector latency and non-linearity for fuel pressure.

 

Closed loop clutch slip control

New for Phase 6 is Clutch Slip Protection . To meet the increasing demands of higher and higher power levels being achieved on a reprogrammed factory ECU, ecutek have added a strategy to adjust the power output to control and prevent clutch slip. This can be used to both impose a torque limit and/or retard the ignition to temporarily reduce power to halt clutch slip to acceptable levels. This strategy will cater for instances where the TCM does not send a torque reduction request after a launch. The Clutch Slip Gain map is used to change the overall torque reduction response to clutch slip, the Torque Limit Gain and Ignition Retard Gain determine how that torque reduction is achieved, this is detailed below.

• Log clutch slip from the ECM using ProECU or ECU Connect
• Prevents damage to the clutch without shutting down power completely
• Closed loop slip control using controlled torque reductions
• Instant reduction in torque using ignition retard
• Sustained reduction in torque using boost target adjustment
• Control activation using Mapswitch Mode, Load, Input Shaft Speed, Vehicle Speed, Shift time, Clutch Slip RPM and Clutch Slip time
• Extend functionality to suit your needs using Custom Maps

See how the slip encountered after shifting is immediately reduced and then controlled in the below example:

 

 

Failsafes

Failsafes are not only essential for remote tuning but also for dyno tuning big power cars as things can go wrong and destroy an engine in the blink of an eye. Keeping engines safe is easier than ever with the introduction of purpose made failsafes. A limp mode style torque limit is activated when any of the following are out of range: Short term fuel trim – Pick up on tuning or fuel system problems Knock retard – Highlight fuel quality issues Fuel pressure* – Eliminate lean conditions before it can occur Air/Fuel Ratio – Catch injector problems Engine oil pressure – Prevent bearing failure on circuit Engine oil temperature – Let the ECU Engine coolant pressure* – Prevent catastrophic head gasket failure Custom Maps Failsafe channel – Create your own satefy measures These can be individually enabled per Mapswitch Mode, and ignored at low load and RPM. Optionally the torque limit can be delayed until cornering force is reduced to an acceptable level, to prevent sudden power loss mid-corner in circuit use. Once triggered a failsafe condition can auto-heal after a configurable time delay, or be reset by keying off and back on. * using an additional sensor configured through Custom Sensors   Limp Mode Stored Flags RaceROM now records the last limp mode so you can check it afterwards, even if the ignition has been switched off, although it’s theoretically possible to trigger more than one at a time I’ve not seen it, but as an example a flag value of 10 would be 2+8 so Low oil pressure and High STFT. For reference the flags are as follows Knock Retard – 1 Low Oil Pressure – 2 High Oil Temp – 4 High STFT – 8 Low Fuel Pressure 16 Lean AFR – 32 High Coolant Pressure – 64 Custom Limp Channel – 128

Enhanced Datalogging

Knowing what’s happening inside a 1500hp GT-R with just 25 logging channels is arguably impossible! RaceROM Phase 6 live data throughput has been increased by up to 50%, the default logging returns 60 parameters at over 40Hz. This can be even be extended to over 100 parameters while maintaining a logging rate of 20hz. Using ECU Connect to combine TCM logging it’s possible to log a massive 245 parameters at a useable 10hz, enabling data capture on a scale not yet seen with OEM GT-R hardware. We have added live data to support the new features in Phase 6, but we have also responded to tuner feedback and added New ECM parameters include: AFR Internal Bank 1 AFR Internal Bank 2 AFR Target Final Bank 1 AFR Target Final Bank 2 BOTL Active flag Clutch Slip Clutch Slip Error Clutch Slip Timer Clutch Slip Exit Timer Clutch Upshift Timer Coolant Pressure CSP Boost Target Limit CSP Flags CSP Ignition Retard CSP Torque Reduction Desired Gear Failsafe Flags Failsafe Stored Flags Failsafe Timer Fuel Temp Compensation Fuel Pressure Fuel Relative Pressure Fuel Pressure Compensation Injector Effective Pulse Width Injector Lag time Injector Low PW Comp Launch Control Active flag Launch RPM Base Launch Timing Base Launch Timing Proportional Launch Timer Torque Limit Final Torque Limit TCM Torque Limit VDC VVT Target

12 Injector Updates

12 injector activation can now be controlled based on ethanol content to prevent secondary injectors from being employed with low ethanol concentration and reduced overall fuel demand.

Boost Control Updates

Phase 6 offers even better closed loop boost control that can be live adjusted from ECU Connect or the cruise control switchgear. Now we’ve added individual base wastegate maps to make Dedicated wastgate base maps for high and low atmospheric pressure makes tuning boost for different altitudes easier than ever Atmospheric pressure dependent boost level for integral activation Throttle threshold for integral activation RPM threshold for overall wastegate activation Gear and IAT based wastegate duty multiplier

FlexFuel Updates

FlexFuel has had further refinements: Ethanol specific boost limit (fuelcut) with blend map Ethanol sensor smoothing Manual Ethanol content override per Mapswitch Mode for premixed fuel

Ignition Timing

Minimum load threshold for Gear/IAT corrections

Speed Density Updates

To help correct airflow calculations for the effects of atmospheric pressure we’ve added simple compensation map to our speed density strategy.

Custom Map Updates

Inputs

Gear Desired Upshift timer Clutch Slip Coolant pressure TCM torque Limit VDC Torque limit VVT Angle

Outputs

New outputs have been added to further extend the capabilities of custom maps including: Custom Limo Mode Torque limit VDC

ECM Updates

In addition to our work on RaceROM we are continually updating ProECU to add more functionality, streamline tuning and make it even easier to use.

EcuTeK Phase 6 costs:

Contact us now to arrange time to upgrade to Phase 6.  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 6 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
