First whats your setup? you will still need the std sensor unless your going to use the sim narrowband output from the wideband, but in any case they use different fittings.

I would be inclined to mount the wideband sensor further back in the exhaust, about 24" or so, although some seem to work quite happily closer to a single turbo.

So you will need to weld on the fitting boss.

I haven't got the instructions but AEM specify a distance for their sensor, it certainly isn't in the downpipe its quite a bit further back. Have a search for "AEM UEGO wideband installation guide" this is a handy guide for the job.

 

 

I ran mine in the downpipe about 6" back from the turbo and had no problems even on numerous top speed runs at 2.5 bar:search:

I have an Innovate setup, but it runs the same Bosch sensor, its strange, when i ran this on my old S14 i had it in the decat pipe, yet i still got overheat errors, so i added a heat sink.

Yet the Supra seems to be OK with it fitted quite close to the turbo, mind you i still have mine in the second decat, must get around to trying it in the down pipe.
