Lamda's

Post by Bennyd » Mon Apr 23, 2012 11:23 am

Hi, I'm having trouble with my car and I think one or 2 lamba's are gone. As a test, is it OK to plug the rear lamda's into the front lamda connectors? And run the car with only 2 lamba's connected. I have my precats gutted so I get the related error anyway. I am currently running the car with all 4 lamda's disconnected, car run fine if a bit thirsty.

With just the precats gutted you shouldn't get any errors imo. I have de-catted mine and was going to use blanking plugs instead of rear lambda sensors. I was advised by Doug to leave the sensors in as the management system still uses them even after de-catting and a stage 2 remap.

Yep, there's a few more tweaks you need to do to the ecu binary if you want to remove the rear sensors completely. Perfectly doable though :thumbs:
