E-85 Wideband?

[Tripod]

AEM has an E-85 Wideband. Is this neccessary with E-85 or will a regular AEM Wideband work just as fine?

[naucrx]

Not needed. The AEM UEGO wideband gauge will work fine for E85 or any premium unleaded fuels.

Yup, regular AEM Wideband will be fine man.

I always tune E85 cars on "pump" scale.

AEM UEGO is my favorite. They have a couple new ones out.

I don't know engines (which will be painfully obvious in a moment), but I'm curious about this. Does stoich with E85 show up on the gauge as 14.7 or 9.7? In other words, do you have to reprogram the ECU to search for 9.7 in closed loop or does it search for and find stoich on its own?

This is good news to me. I had just ordered the AEM wideband and I would hate to have to need another. Thanks guys!

I say the AEM UEGO will be your best bet. Lots of E85 cars tuned on this wideband.

when you have it set to gas it will show 14.7 with e85.

Got it. So it's really lambda plus an assumption that it's gas, allowing it to effectively multiple lambda by 14.7 for the gauge's display. Is that it?

[Golden]

Yeah, that's it.

I suppose we should all really just use lambda. But I'm not used to it.

It's just AEM trying to make that extra buck ;-)
