The kit comes with the following:
1 x Syvecs S7Plus
1 x GDI12 Driver
1 x MQB Wiring Adaptor
Installation
- Remove the Negative Terminal from the battery on the Vehicle
- Remove the OEM Engine control modules found in the engine bay next to the battery
- Remove the OEM Ecu Holder which is held in place with 2xM6 nuts
- Replace with the Syvecs kit
MQB Specific Software Options
Due to the number of Cars that the MQB Engine is fitted to, an ECU Coding
setup needs adjusting in Scal to suit the model of your VAG Group Car.
This is found at the bottom under I/O Configuration Car Coding4 Values
Golf R7 DSG – 0
Golf GTI DSG ‐ 1
Seat Leon Cupra DSG – 2
Golf R7 Manual – 3
Golf GTI Manual – 4
Seat Leon Cupra Manual ‐ 5
Audi S3 DSG – 6
Audi TT – 7
Golf R7 DSG Other Regions – 8
DSG TCM Logging
The Syvecs kit allows logging of the Clutch pressures from the DSG Gearbox. To
enable this Set Car Code1 = 1
IMPORTANT – WHEN DOING GEAR RELEARNS OR COMMUNICATIONS WITH THE DSG ECU
VIA VAGCOM SET THIS CARCODE1 = 0
Injector Size is set in Fuel Consumption – Injector Consumption Scaling for
Torque Control
Injector Size / 60 = ml/s value
OEM DI Injectors are set in the Base map @ 16ml/s
MQB Kit FAQ and Help
Q) Do you control the OEM Intake Flaps
A) Yes, This is set in Output Functions – Fan7 (Intake Flap), Its controlled Based on RPM vs Manifold Pressure IntakeFlapP_U01 is Position sensor 100% is Closed, 0% is Open
Q) Do you control the Exhaust Cam Lift Solenoids
A) Yes, This is adjustable in Output Function – Variable Cam Control
Q) How is the Piston Cooling Oil Valves controlled?
A) This is found in Output Functions – Fan4 (Oil Cooling), Its controlled Based on Load
Q) How is the Electronic Blow of Valve controlled
A) This is found in Output Functions – Fan5 (Turbo Recirc) , Its controlled via Throttle Angle, Manifold Presure and RPM
Q) Does the Different Drive Modes from the Car comes into Scal
A) DriveMode Comes in on Slave AN22 - Comfort = 10%, Normal = 20%, Race = 30%, TC Off = 50%
Q) How is the Electric Wastegate controlled on the OEM Golf 7 Turbo
A) Boost control is on Supercharger Bypass Strategy, (SBV = 0 is WG Shut, SBV = 100 is WG Open) . If changing to External WG need to change to Custom Can - Transmit content Frame 2 Slot 2 to WGTarget1
Q) How is the Electric Thermostat Controlled
A) This is Controlable in Output Function – Fan8 (Coolant Flow Control ) - Coolant Thermostat Position (CTP) at 0% means Thermostat is Open Fully, 100% means Closed Fully
Q) Can I install different in tank pump?
A) Yes, the Syvecs communicates with the OEM Fuel Pump Ecu to allow PWM Control of the Pump so it can be adjusted to suit your new pump. This is found in Output Function – Fuel Pump - Fuel Pump PWM 1 Control
Q) What of the original features will no longer work?
A) All original features will function properly
Q) Can we use the OBD port still to Log, Read Codes and Clear them on other ecus on the car like ABS?
A) Yes via the Use on VagCom
Q) How do I adjust the Port Injector Sizing
First set the Secondary Injector Opening times in RunMode Fueling – Corrections After you need to set the Secondary multipler difference between the DI and Port under Run mode fueling – Correction – Secondary Multipler OEM DI Injectors flow around 650cc.. So do 650 / (Port Injectors cc) to give a good starting point on Secondary multiplier Ensure that the Secondary Injection Opening Time values are correct from your manufacture. After Start the engine up and monitor the Lambda1 Value and FuelMltCll1 Value. Now go to Injector Split1 and increase the values up to 50% in the area and around that the tracer is showing the engine is current at. As the Ports start to blend in and you have the Split at 50% you need to be monitoring the Lambda1 and FuelmltCll1. If the values are different compared to before when split was at 0% then adjust the Secondary multiplier live until they are the same with the split present.. Once that is good, set the Split back to 0%, When the OEM DI Injectors now reach their limit the Syvecs ecu will automatically bring the ports in to maintain the desired fuel requirements, If you wish to bring the port injectors in sooner then set the split table as required.
