Exhaust valve open mod - How To Video - F80 F82 F83 M3 and M4
Whipped this up today while doing the exhaust valve mod. It is so easy I don't know why anyone needs a video...but just in case.

Basically I taped up the connector with electrical tape and then looped it through on itself a couple times. Another idea would be to use a ziplock bag around the connector and harness and tape it up around the opening. I did that with a wide band sensor for a while under my Miata until I needed it.

I'm a little curious how it might affect MPG in part throttle low rpm. |

Really nice! Thanks for the Explanation!
But isn't it like the valves should be closed during cold start, that the cats can warm up faster?! Shouldn't make a big difference, but it would mean that it takes a little longer until the components have reached their working temperature, right? |

Not sure. I'm getting a 1-1.5mpg discrepancy between computer and actual mileage. My wife F80 does not have the mod and her computer/actual is only off by 0.5mpg or so.
I don't recall how accurate mine was before. I will keep an eye on this. Overall I seem to have the same average MPG per tank (indicated) as I did before. |
