That makes sence with the headlights.

I run what is called a powercard, it is a piggyback system that works very well with the supercharger.

I would gain maybe 10hp or so with a megasquirt etc but this system works perfectly. (maybe one day)

Phew, from what I read I thought you were running boosted on the stock ECU and only just got a wideband! :oops:

It is not that brand but I would guess to say it is the same way of installing it.

So I will take out the standard ox sensor all together and install the wideband one in its place, looks like this is the way to go.

If that does not work I have the bung to weld in if I have too.

If you are using the standard ecu you wont be able to feed it the wide band signal since it uses a 5v output and a narrow band uses 1v.

Wideband controllers like Innovate have two separate configurable outputs so you can use one with a linea 5v output to go to the gauge and a 1v
narrowband simulation to go to the ecu.

If you are using an ecu that can take a 5v wideband signal, you can configure the ecu output on the wideband controller to wideband.

If you are using the likes of a G1 FlyinMiatalink wich uses a AEM nonlinea wideband input you can configure the output curve to match

Hope this helps
