Sterling Posted September 29, 2020 Report Share Posted September 29, 2020 I'm not sure what to do with the Lambda heater wire. I have an Innovate LC-1 that's been working fine for me with my previous system and that system did not call for a specific input into the ECU for the heater wire. I only connected the signal wire from the LC-1 to the ECU and it worked fine. Please advise, can I just hook up the signal wire from LC-1 to the G4+ or do I need to take the heater wire from the LC-1 and hook that up as well? Not sure why it matters. Thanks in advance Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 29, 2020 Report Share Posted September 29, 2020 Why do you think the heater needs to be connected to the ecu? With any wideband the heater can only be controlled by the wideband controller. The only thing that should be connected to the ecu is the 0-5V analog output.

Sterling Posted September 29, 2020 Author Report Share Posted September 29, 2020 For some reason I thought I saw the heater on a separate input, guess it's not necessary or I misread. Quote Link to comment Share on other sites More sharing options...
kaptainballistik Posted June 6, 2021 Report Share Posted June 6, 2021 Jumping in on an old thread... I too have noted the Injector 7 O2 sensor heater driver. It would be nice to have the ECU switch the Heater on when the ECU "running"... Is the ECU capable of switching (to ground) something like an innovative LC-1 O2 sensor unit, or should it ground out a relay? (or can I set it high to trigger a relay?)

Confused Posted June 6, 2021 Report Share Posted June 6, 2021 That's for a Narrowband O2 sensor, which doesn't have a controller. If you have a habit of sitting with the ignition on and engine off, your best bet is to power the LC-1 via a Relay, which is controlled by the ECU (relay coil has ignition power one side, ECU output the other), so that it only powers up the LC-1 controller after the engine has been running for a few seconds.

kaptainballistik Posted June 6, 2021 Report Share Posted June 6, 2021 That sounds like the ticket! (Especially the ability to switch on as the car starts!) Quote Link to comment Share on other sites More sharing options...
