The kit comes with the following:
1 x Syvecs S7Plus
1 x SGTR Loom
Installation

1. Remove the Negative Terminal from the battery on the Vehicle
2. Remove the Glove box from inside the car as shown below
3. Remove the Glove box Support
4. The Stock R35GTR ECU can then be unplugged by removing the 3 plugs. After doing this loosen the 4 M6 nuts to remove the ecu completely from the vehicle
5. Connect back the 3 ECU loom plugs into the Syvecs loom
6.  Refit the Glove box support and fit the Syvecs Ethernet Cable via the side holes
7. Refit glovebox
8. Re-Connect the Negative terminal of the Battery
9. Contact Support@Syvecs.co.uk for a base map and Software basic Manual

R35GTR – Torque Control Notes & Tips

Depending on the Software version (firmware version) of the base map or current map present in the ecu, you will find that the torque control is done is different manners. Firmware which is pre 1.43 uses just one table for adjusting the torque values sent to the Transmission ecu for handling clutch control. This table is called the MBT Torque Estimate table and is based on Primary Load vs RPM. The table can be adjusted live to cater for shifting smoothness and clutch clamping. The Values in the MBT Torque Estimate table are not the final values sent to the TCM as friction loses and other multipliers for airtemp etc are applied so to view the actual value sent, Open up a Gauge for engTrqEstOutputTrans.
Firmware versions which are 1.43 and above now have the ability to automatically calculate torque which from in-house testing significantly improves the drivability of the kit.Before where the torque table was set manually against RPM vs Manifold pressure in certain situations manifold pressure has a filling/usage delay which we have found effects shifting in transient states.
In order for this strategy to work accurately a user needs to input a Fuel Consumption amount in the map below. This map is set in ml/s
Generally a good calculation for this is Injector Size in CC / 60 but base fuel pressure has a large effect also so ask you injector manufacture for Torque Control Flow Values if not below.
Some Values already received at the OEM Nissan Base Fuel Pressure
ID2000 @ 3.5bar = 35
ID1300 @ 3.5bar = 21
Ansu 1100cc @ 3.5bar = 17
Ansu 1650 @ 3.5bar = 25
Tip:
With Either Torque Control estimation method its best to make sure the engTrqEstOutputTrans values at idle at around 2-8 Nm. If using firmware 1.43 and above then adjust the thermal efficiency table to achieve this…. If below 1.43 then set this manually in the Estimated MBT Torque table.

R35GTR – Map/Calibration Switching

Map/Calibration Switching on the SGTR Syvecs kit is done via the OEM Cruise control Switches, when the ignition is switched on it will always default to CalSwitch = 1 in Scal which is found in the parameters list on the right hand side when connected to the Ecu. By Pressing the Res/Accel button on the steering wheel you will find that the calibration switch goes up by one value each time its pressed. As default there are 8 calibration switch options and the user can then assign many tasks to each calibration switch under the Calibration switches section of Scal.
The Engine Coolant temp display will show the current Calibration switch in the first digit upon map changing. Ie 10c will be Cal1 and 20c will be Cal2 The Coast/Set button is used to go back down the Calibration switch positions
During Calibration Switch changes the Oil Temp Display will also show the Flex Fuel %
The Cancel Button activates the Calibration Override Switch in Scal which as default in the base maps jumps to Calibration Switch 9 for activating Rolling Antilag. By Holding down the button and going full throttle in manual mode a Antilag strategy will be activated which holds the car back from accelerating but builds boost. Upon releasing the switch the Antilag is disabled and the engine will gain torque instantly to accelerate.

Launch Control

In order for Launch control to activate and allow the Throttles to open with the Syvecs Kit a Launch control mode must be installed inside the Transmission ecu. Ecutek or Cobb caters for this on the early cars but on models My11 onwards it is enabled as default.
(The OEM Ecu is required to be fitted for flashing the TCM)
Selecting R Mode on the Transmission and VDC Off is the normal procedure followed by selecting First gear, applying the brake and going full throttle on the Accelerator pedal. While doing this the Launch control strategy of the SGTR will become active and a desired RPM and Manifold pressure can be set in the Launch control strategy as shown below.

Automatic Up Shift using Syvecs S7 R35GTR Kit

First find the connector M7 which is found on the drivers side of the R35Gtr
ON RIGHT HAND DRIVE CARS THIS IS FOUND ON THE SAME SIDE BY THE ECU The M7 connector is the one which has the thinner gauge wires going to the plug Unplug by lifting over the Grey locking arm and then pull the plug from the housing Now take off the back cover of the connector by lifting the 4 tags and lifting off the cover.
The wire which you are looking for is a white wire which is the one that has the insulation shaved back in the below picture. T a wire into this wire and then direct it over to the S7 Ecu. This White wire is pin 22 of the below pinout to help if the colour is different on your model.
We recommend you always check it is the connector wire first before pinning into a spare output on the S7. By using a multimeter and check when you pull the Up shift lever this wire goes to Ground Once wired into the S7, make a note of the output chosen and then assign this to the Change Light in the I/O Config of Scal.
Then you can define the set Vehicle speed which first must be met to stop early shifting if the driven wheels spin… then set the engine speed you wish to shift at per gear.

Limp Modes

The Syvecs SGTR kit is geared around safety and many Limp become present if certain parameters are not within a set value. The Ecu Light and Gauges present the level of Limp. Levels below:
Warnings :
Limp Level 1 (no key on -off ) is Solid CEL
