Cool! As long as I can still rock 80mph for those long, long trips on the 5 I am down.

Probably you're holding worlds slowest n55 record out there too.

That would be the perfect valet!!
It seems that this Naturally Aspirated Map would be the perfect time to re-introduce the adjustable Valet Speed Limit setting from the past, as it would only be relevant when the NA map is selected.

Agreed, but the valet mode should include a rev limiter to maybe 4000-4500 max? Don't ask, was once a valet and those of you guys who don't know, you don't even want to start to imagine what some of these guys do to your car.

Shiv, any word on mpg improvement in NA mode? I'm curious about how much of an improvement there would be over normal highway cruising when there would be very little boost anyways.

I could see the lowered exhaust backpressure with the wastegates open making the volumetric efficiency better.

You'll notice that the datalog channel list has been updated. No more debug byte/words but proper titles instead.
You'll also notice that the Naturally Aspirated mode is functional. And pretty slow. Still some ignition advance mapping to do before it is released. There's a lot more power to be made still. And improvements to fuel economy as well. I'll be tuning it on my car when I get back to the office tomorrow.

Other udpates include revised Nitrous control and new in-dash gauge options (intake air temp and ignition advance displays). A few other things too

Cheers,
shiv
bingo....thank you Sir!!
