wideband / e manage

[daveeclipse99]

can i just buy a aem wideband o2 sensor and tune it with my new e manage ? or do i have to buy the controller and gauge too ?

thanks

You must at least have the controller. You cannot simply just connect a WB sensor up and expect it to work. You may not need a gauge if you can input the AFR to emanage. It still may be wise to have one just so you will catch it if the car goes dangerously lean under boost.

For the AEM wideband the gauge IS the controller. The gauge has an output wire that then goes to your e manage.
