Exhaust valve open mod - How To Video

Accel Junky · 11-29-2014, 04:20 PM

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.

Thanks for that, handy to see, and do, very easy, not a golf tee in sight

Who's enjoying their M3 the most!?

Very good video...nice and easy.

jim101 · 11-29-2014, 05:51 PM

Nice...what did you tape the connector to, the harness? What kind of tape did you use, electrical?

TIA.

Well...I love mine but my wife has instituted a no food/drink policy in hers and I get berated if I drag my feet on the door sills

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.

does this throw up any codes when you bring the car to the dealer or any lights?

I'll have to report back on that. So far no lights. Maybe someone else who has had the mod for longer can chime in?

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

Well considering I always drive in sport cuz I wanted the open valves, my mpg should go up now since I can drive in efficient mode and have the sound!

Thanks a lot mi amigo!

Disconnected mine weeks ago. No dash lights.

Great video! Seems like an extremely easy mod to do!

Nice! I will be doing this tomorrow!

aweso///Me · 11-30-2014, 05:51 AM

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?

Easy peasy, and sounds a lot better for zero dollars.

BPe90M3 · 01-19-2015, 04:02 PM

is it me or did this kill my MPG?

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.

Can anyone comment on whether this voids any warranty/OK to perform on a leased car? (assuming put back into place before returning)

Any issues when getting service done?

f82mw · 05-18-2015, 06:36 PM

Would also like to know if this kill MPG.. so do you end up bringing it to the dealer?

I can't say for sure but I would be shocked considering you aren't materially altering the parts.
