Ramantanis Dimitris Posted September 4, 2015 Report Share Posted September 4, 2015 Hi, I'm looking to connect my stock 4agze 1wire knock sensor with my i88. Do they work properly with this ecu or I shal replace this with a two wire knock sensor model? Quote Link to comment Share on other sites More sharing options...

Simon Posted September 7, 2015 Report Share Posted September 7, 2015 The Bosch 2 wire do tend to just work on just about all applications.But no reason not to try the stock sensor. Quote Link to comment Share on other sites More sharing options...
Davidv Posted September 20, 2015 Report Share Posted September 20, 2015 Generally speaking (newer vehicle knock sensors seem to be fussier) the Toyota knock sensors are filtered inside the sensor, as in, they only pick up a particular frequency.Which is great except for if knock starts happening outside of that narrow frequency range (Which can happen if bore or stroke changes, or you've got a knock sensor from the wrong motor)The bosch ones are wideband knock sensors that pick up everything, then you can use the ECU to filter to the correct frequency of knock.From previous experiences (troubleshooting a factory ECU'd car with the wrong knock sensor) I'd be inclined to use the bosch ones all the time for aftermarket ECUs where it's configurable.
