Low 30s at what speed?

Lol, semi legal speeds, not real speeds.

And, obc indicated, not calculated.
(But I assume the obc is the same level of optimism on the 328i as M3)

I just have trouble seeing the S54, the most polluting and highest specific output engine BMW ever offered, getting significantly better fuel economy than it does stock, when stock it's already better than the e91 with N52... an engine build in the efficient dynamics, government mandated corporate average fuel economy era.

But, I also wouldn't have thought current power output levels were possible 5 years ago, so maybe I'll be surprised.

Don't think a fuel saver mode would really be too worth it. The valet mode would be definitely handy tho.

Default Re: map switching

efficiency? LOL that not gonna happen and it will be waste of time i think. if you want efficiency watch your right foot.

GM Flex Fuel Sensor tied in with Bigger injectors, and a switchable e85 tune, I can only dream of this to happen.

I remember a member(forget his username) running a tuned Cam'd N/A on e85 making close to 400whp.

Great Work guys!

This project became much more complicated than anticipated, but I have all the bugs sorted out !

Available at http://www.msstuning.com/

I've also finished a decent Valet tune

Wow, simply amazing paffy!

Will be a customer if/when you implement on mss52!

Fantastic work!

One last question.. Can you implement the "always report readiness pid" in mssflasher?

I could probably do MSS52, but it would require soldering larger EEPROMs.

"always report readiness pid" is not something that I feel comfortable putting officially out there, even if for off-road use only.

I don't think there's enough room to switch between 8 tunes on the MSS52/4. Should be able to switch between two however depending on how large paffy's switching code is

Soldering 400s on the mss52 are not a problem. I'll be anxiousy awaiting that implementation!

I totally understand your stance on the readiness topic.

Again, very nice work.
