Just the upstream. Cobb stage 2 tune shuts off the downstream.

I guess I should have known that considering aftermarket downpipes only have one. Upstream is the one closest to the midpipe then?

Upstream is on the exhaust manifold. It's actually a wideband limited to reading 11.2:1 on the rich side. Very accurate while not in boost.

Misfire is gone, so far. I drove around 2800-3200 rpm uphill and in 85* heat and slowly accelerated to 80 mph on 6th.

The car feels good. It seems the ecu is adjusting itself in a good way. I guess a bad O2 sensor will not throw a CEL specifying a bad O2 sensor. Good enough to not throw an O2 sensor related CEL, bad enough to make a car run poorly and throw a P0303 #3 misfire code.

Don't you hate it when your gas cap breaks right when you're about to fill up?

I fixed a leaking lower radiator hose. It's been leaking for about a month. It was hard to spot the leak but the smell of coolant was there. It finally was visible when the leak spread further covering part of the aluminum header wrap. So far, it's not leaking and the temps are more steady. It even feels more peppy. Maybe the old coolant had cleaned off the sensors, I don't know. Or maybe the Motul Mocool is doing its job helping with the heat transfer.

From what I've read on Delicious Tuning's website, the flex fuel kit is the ideal set-up for someone who transitions between 91 octane and E85 on a regular basis, yet it eliminates the need to swap back and forth between maps. It almost sounds too good to be true, so I'll be interested to read your reviews of real-world/daily use. Cheers

I had this thing sitting for almost a year and I decided to install it now.
