LINK G4X Honda K20x PlugIn ECU - Civic / Integra / Acura / CR-V
Free yourself from the limitations of manufacturer control units!
Easy to install. Affordable. Reliable. G4X Plug-In ECUs offer the latest engine management technology, designed to easily maximize your vehicle's potential. This ECU fits into the factory OEM housing. Installation is a breeze, with no modification to the factory wiring harness required for the models listed below.
Designed for the K20A engine.- Please check your connector matches the header in the listed photo before purchasing.
- This ECU only works for manual transmissions
- ECU contains a 7 bar MAP sensor on board
- Most factory functions are supported
- Check the Features tab for I/O expansion options.
Note: This plug-in has a new 4-pin powered CAN connector and cannot use the old CANPCB cable for the CAN connection.
Use the CANJST4 (code 101-0198) cable to connect CAN devices.
This new 4-pin connector and cable not only provides the CAN connection, but also a protected 12V power supply and ground for powering the CAN devices.
The power supply is protected by a self-resetting fuse with a continuous rating of 3A.
Suitable applications (manual transmission only):
Honda Integra Type R DC5 2002-2004 with K20A/K20A2/K20A3 engine
Acura RSX 2002-2004 with K20A/K20A2/K20A3 engine
Honda Civic Type R EP3 2001-2005 with K20A engine
Honda Civic Si/SiR 2001-2005 with K20A3
Honda Civic DX/LX/HX 2001-2005 with D17A1/A2/A3 engine
Honda CR-V 2002-2004 with K24A1 engine
Installation is possible without costly modifications to the original wiring harness. Additional connectors or pins provide expansion options such as oil pressure input or anti-lag/logging switches.
Most of the vehicle's original functions are supported. Exceptions can be found in the data sheet.
The new Link PluginX control units are the second-newest version of the LINK control units. This generation is more responsive and has a higher bandwidth than its predecessor, the G4+.
G4X offers 8x faster communication speed, allowing you to download data logs 8x faster and quickly transfer the entire log to a new and improved PCLink software.
G4X has 512 MB of 32-bit integrated data logging with up to 250 channels, each limited to 1000 Hz per channel (by the operating system), with a maximum combined 100 kSamples/s.
Do you need additional inputs/outputs?
The Maptec or Link XS additional wiring harness offers the possibility to use additional inputs/outputs of our PlugIn ECUs.
