If I wanted to add an EGT guage as well as a wideband A/F ratio guage would that require 2 extra holes in the DP for a total of 3? 1 for the stock O2 sensor. 1 for the EGT. 1 for the wideband. Is that correct? What order should the sensors go on the DP?

Thanks

Depending on how far down the o2 sensor bung is placed, you may be able to use that for your wideband sensor bung and just have the wideband controller send a simulated narrowband output to the ecu. Otherwise, you want the wideband sensor bung at the bottom of the downpipe, where it flattens out.

You want the EGT as far up as possible, ideally it would be mounted in the manifold before the turbos.

 

Thanks, That's got to be a pain in the *** to mount the EGT bung up there. Anybody put one there, better yet any pics?
