CAN based Lambda v Voltage Based Lambda Controllers.
You either know CAN based Lambda Controllers are better or you don’t.
Here is 5 good reasons to use a CAN based lambda over an old fashioned analogue one.
1. CAN based lambda controllers are not reliant on analogue to digital converters inside the ECU allowing for a faster reading; see the graph in the photo this shows a Haltech Lambda over CAN (blue trace) and an analogue AFR gauge connected to an Analogue input and clearly shows a typical delay. (Both sensors were fitted in the same position)
2. CAN lambdas are immune to false readings due to wiring issues between the controller and the ECU. We often see a slightly off ground giving false AFR readings which can be disastrous to the engine. They also do not need a calibration table, we often see ECU’s setup and using the wrong calibration.
3. CAN based controllers use signals from the ECU to time the heating of the lambda sensor protecting them from condensation based thermal shock which is by far the biggest reason for premature sensor failure.
4. CAN based lambdas send controller status back to the ECU so the ECU knows if the sensor is functioning correctly.
5. You can run multiple sensors and not use any valuable ECU inputs. All communications happen over the CAN BUS.
At BHP we have helped pioneer some of this technology with our suppliers, we have the largest choice of devices so who better to choose to build you a solution that’s robust and works out the box.
