Our Classic Fuel Injection systems are E10 fuel compatible
Classic Fuel Injection Wideband Lambda Controller for Bosch LSU4.9 Sensors
Our CFI Wideband Lambda controller is based on the industry leading products from 14point7
It is designed to use with the Bosch LSU 4.9 Wideband O2 Sensor
We have custom designed the PCB and fitted into a waterproof enclosure for engine bay mounting.
Wiring interface is per the sealed IP67 Molex connector
Compatible with all fuel types ( E0, E5, E10, E85 )
Lambda Range: 0.68 Lambda linear to 1.36 Lambda
0.01 Lambda accuracy without the need for free air calibration
Linear output allows easy interfacing with gauges, fuel management systems, and dataloggers
Linear Output:
0v @ 0.68 Lambda to 5v @1.36 Lambda
equates to 10 AFR to 20 AFR equivalent for gasoline
Simulated Narrowband Output allows you to install a Wideband O2 Sensor in place of your Narrowband O2 sensor
Switch point @ Lambda 1.0 - 14.7 AFR equivalent for gasoline
Designed for use with the Bosch LSU 4.9 Wideband O2 Sensor or Bosch compatible parts with the correct calibration resistor fitted
( The cheap clone sensors tend not to have the correct resistor fitted so will not display accurate results )
All sensors that we stock are Bosch geniuine or a proven and tested
compatible products and do not require the Free Air Calibration Mode

IMPORTANT INFORMATION RELATING TO OUR COMPLETE FUEL INJECTION VEHICLE KITS
These kits are only suitable for vehicles with a Negative Earth electrical system.
If your vehicle is the older Positive Earth then you must convert the vehicle to Negative Earth before fitment.
Many older vehicles have already been converted but if you need to convert this is normally a simple process often cost free.
The full vehicle kits will normally be supplied with the ECU pre loaded with an initial start file.
This initial start file is simply provided as an aid for
engine starting, it should not be considered a suitable final
calibration for your engine.
You must be prepared to undertake further ECU calibration work to ensure the ECU files are tailored to your vehicle.
Failure to successfully complete the calibration process may lead to poor vehicle driveability or even damage to your engine.
Our Classic Fuel Injection Kits are custom built to order and to the
customer general specification and as such are exempt from automatic
return rights under Consumer Contract regulations.
By ordering this
conversion kit you understand that further ECU calibration work will be
required and the final results are outside of our control.
We cannot accept returns or claims arising from failure to successfully complete the calibration process.
