Gallardo LP520 Kit
Thank you for choosing the Syvecs LP520 Gallardo kit
The kit comes with the following:
1 x Syvecs S12 Ecu
1 x Gallardo LP520 Wiring Loom
1 x 10way GT Connector
1 x Syvecs GFA Module Adaptor
Installation
1.) Remove the Negative Terminal from the battery on the Vehicle
2.) Remove the Carpet/Panel behind the driver/passenger seats
3.) Remove the OEM Engine control modules. Look like below.
Mark the Module on the right hand side of the vehicle when looking from behind the vehicle as 29R
4.) Next plug in each end of the Syvecs loom as labelled on the connectors to the correct side of the car.
29R – Right hand side of the car looking from the Rear of Vehicle
29L – Left hand side of the car looking from the Rear of Vehicle
5.) Mount the S12 Ecu in the Location shown below by removing the inside noise panel and trimming to the shape of the
S12 Ecu so it fit neatly behind the passenger seat and secure using the Double sided velcro tape
6.) After securing the ecu and associated wires head down to the passenger area footwell. Remove the carpet piece and
loosen the 4 screws shown below to expose the GFA Unit
7.) Unplug the 4 connectors into the GFA and fit the Syvecs GFA Module in‐between the loom and the GFA Module as
shown below
8.) Now remove the Terminator plug as shown below next to the GFA Module
9.) If wanting to control/monitor external device these can be wired into the 12way DTM break out connector found
coming out of the S12 Looms. We suggest wiring in the Throttle bodies direct on the 2008 models which use the Bosch
Throttle body units – Pinouts found on last pages.
10.) Refit all carpets and panels
11.) Re‐Connect the Negative terminal of the Battery
Gallardo 2004 – 2006 Wideband Connection
The 2004 – 2006 Gallardo's do not come as standard with Wideband Lambda sensors but do have wiring in place for them to
be fitted.
The 2006 – 2008 models have an NTK Wideband Lambdas fitted from the factory, the part number of this sensor is NGK
LAMBDA SENSOR LZA11-V4. You are able to use this sensor on the early models and the connectors are found either side of the
engine as shown below in the image. We recommend to use a NTK Sensor but if you wish to use an LSU4.9 then see wiring at
the bottom of this page.
If you are wanting to hook up a Bosch LSU4 sensor then the pinouts for this connector are shown below and where they link to
on the Syvecs S12.

Gallardo Throttle Body Connection
The 2004 – 2007 Gallardo’s come with internal can bus based throttles made by magneti marelli which only have power,
ground and a canbus connection. We used to support these units via canbus but found them to be unreliable. We now
suggest that users wire in Bosch Throttles for added control and safety.
The Bosch throttle - Part Number 07D 133 062 bolts directly onto the original intake of the Gallardo
These units will need to be wired directly back to the ECU, so a new Loom is required to be made and linked into the 10way
GT150 Connector supplied next to the S12 Ecu. Wiring Below
The later models LP520 (08-09) did come with Bosch Throttles from the factory and these can be used no problem.

Gallardo 2008 Lift Wiring
The Gallardo LP520 came with an option for Front lift control in certain models. When fitting the Syvecs kit this will no longer
work as certain functions are bypassed during the installation on the GFA unit. To make it work it needs to be wired back from
the GFA Patch harness to the S12 as shown below.
Cut GFA 406 - Pin25 and Connector Harness side of wire to S12 Pin 62 ( Solenoid Down )
Cut GFA 406 - Pin12 and Connector Harness side of wire to S12 Pin 81 ( Solenoid Up )
T Into GFA 406 - Pin16 and connect to S12 Pin 14 (Lift Switch)
T Into GFA 407 - Pin12 and connect to S12 Pin 12 (Lift Positon)
Frequently Asked Questions
Question : Where is the OEM Map sensor and what does it read to?
Answer: The OEM Map sensor is found in the middle of the intake manifold and it only reads to 4 psi so if going turbo you
can directly replace this part with a 3bar Map sensor - Part number 0281002977
Question : Does the kit support 20 Injectors? i can only find 7 outputs that is available.
Answer: The Kit as standard only supports 10 Injectors, if you want to do 20
Injectors you will need to move some of the Pins to different outputs
Suggestions for this:
Move Tacho Output - Pin 121 (Fuel7) to Pin 91 (Pwm3)
Move Lambda Heater - Pin 94 ( Fuel15) to Pin 108 (Pwm5)
Move OILT PWM - Pin 101 (Fuel10) to Pin 81 (H Bridge 6)
This will Free up 3 Injector outputs
Question : Boost solenoid... Can i use any existing wires for that? Variable intake is am not using, can i use this connector
in engine bay
Answer: yes can use the Variable Intake connections if you have a turbo installation - Goes to PWM 2
Question : Can i use any existing button on the car for changing Calibrations ?
Answer: On Egear models the Sport Button goes to the ECU on AN10, Manual will need a external cal switch
Question : I have lost the spare pins which come in the kit, can i order some more
Answer: You can order extra pins if the Dealer has lost these quickly from local electronics supplies like Farnell, Digikey
