7. Plug in the connectors from the OEM Loom into the Syvecs 911 Ecu.
8. If using on a 996, wire a Syvecs Cal Switch for map switching into the 26way ACC connection on the PNP Ecu; on the 997, use OEM Functions on the Cruise level for map switching.
9. Refit the Ecu Cradle, Carpet and route the Syvecs Ethernet Cable down the side of the carpet.
10. Re-Connect the Negative terminal of the Battery.

Firmware and Module Coding Setup
Depending on the firmware version, follow specific module coding setups for Porsche 996 and 997 models as outlined in the manual.

Torque Control
The torque control process differs based on firmware versions. Older versions use M BT Torque Estimate table for adjusting torque values sent to the Transmission ecu, while newer versions can automatically calculate torque for improved drivability.

FAQ

Q: How do I switch maps on my Porsche 996/997 Turbo using Syvecs S7Plus PNP Ecu?
A: For Porsche 996, wire a Syvecs Cal Switch into the 26way ACC connection on the PNP Ecu. For Porsche 997, use OEM Functions on the Cruise level for map switching.

Installation

1. Remove the Negative Terminal from the battery on the Vehicle which is found in the front trunk of the car as shown below
2. Pull down the back seats in the rear of the cabin
3. If a subwoofer is present, pull off the Bose speak cover clips and using a torque fitting unscrew each bolt on both sides. Then lift out the Subwoofer and unclip the electrical connector
4. Lift the carpet to reveal the Ecu Cradle which is removed by 3 x M6 nuts
5. Remove the OEM Ecu by unclipping the 5 x Connectors and unscrewing the 4 x M6 Bolts in each corner
6. Next Mount the Syvecs PNP ECU onto the Factory bracket, it will bolt straight into the OEM Location
7. Plug in the 5 connectors from the OEM Loom into the Syvecs 911 Ecu
8. If using on a 996 then you can wire a Syvecs Cal Switch for map switching into the 26way ACC connection on the PNP Ecu. On the 997 its done via OEM Functions on the Cruise level which are explained more below
9. Refit the Ecu Cradle, Carpet and route the Syvecs Ethernet Cable via down the side of the carpet.
10. Re-Connect the Negative terminal of the Battery
11. Contact Support@Syvecs.co.uk for a base map and Software basic Manual

996 Module Coding Setup

CarCode 1 is Transmission Type ———————————
0 – Manual
1- TipTronic

997 Module Coding Setup

• CarCode 1 is Car Model –
• Cayman = 64
• C4S = 66
• Turbo = 67
• GT2/GT3 V1 = 70
• GT2/GT3 V2 = 71
• CarCode 2 is Trans Type
• Manual Trans = 128
• Tiptronic = 129
• CarCode 3 set the Module Coding ———————————————-
• Most Cars = 255
• C4S, Cayman = 229
• GT3 V1 = 234

Examples
Turbo Manual – CarCode 1 = 67 , Car Code 2 = 128 , Car Code 3 = 255 Turbo TipTronic – CarCode 1 = 67 , Car Code 2 = 129 , Car Code 3 = 255

S911 – 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 1.42 on older S6 kit 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 on S6 and any S7 now have the ability to automatically calculate torque which from in-house testing significantly improves the drivability of the kit as 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 different base Fuel Pressures

• 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.

S911 – 997 Map/Calibration Switching
Map/Calibration Switching on the S911 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.

First pressing the cruise cruise button the end of the stalk will put the car into map switching mode which flashes the cruise control light on the dash. When in this mode pushing the Resume button on the steering wheel up and holding for 2 seconds will make the calibration switch go up by one value each time its pressed and held. 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.

Pushing the stalk button down towards the Off Symbol and holding is used to go back down the Calibration switch positions.
The Boost gauge will display the Calibration Switch Change in Bar format i.e 0.1bar is Cal1, 0.2bar is Cal2

Pulling the lever towards the driver (Speed/Set) activates the Calibration Override Switch in Scal which as default in the base maps jumps to Calibration Switch 9 for activating Rolling Antilag. By pulling back the stalk 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.

Limp Modes

The Syvecs S911 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:
Cycling the Ignition on the 911 Resets the Limp
