I was wondering if any has used the AEM wideband gauge with a haltech. I know I have used them before and they work great, but I never used it with a haltech. I'm using a e8 with the patch harness to use the factory wiring.

The AEM is the absolute worst unit on the market. I have never, ever, one time, EVER, seen one of those things be accurate. I don't mean to frivolously slam your product, but that's what the deal is. My recommendation would be to not take the time to wire it in to the Haltech (which is easy, by the way; just grab the 5V O2 output lead and send it to the Haltech's O2 input lead).

I recommend using a wideband that utilizes an NTK sensor.

You have the patch harness, so the easiest way to connect the wideband is to use the Spare A/D 2 input. That is the 3-pin Weatherpack aux connector. The output wire from the AEM will mate to the center pin of the Weatherpack.

I have to disagree with Brian. Innovate is the worst of the lot.
