Are you telling me that with this map I can get 34-38 mpg? Cause, that's kind-a difficult for a 3L engine that has to haul around close to 1.5 tons...

Just saying...

My old 325i would get 46mpg (UK) on a cruise, so it's possible I think. The turbos really drink the fuel when the accelerator is applied.

This feature will be nice but just for the fuel that you consume. I'll like to keep performance the same. What I would like to see is when we pull up to a valet and before we handing them the keys we can just triple press the DTC button to put any maps we are in to cap he Rev to 3000rpm and speed limit to 40mph.

Your old 325 had a smaller engine and it was MUCH lighter car. Besides, the turbos don't kick in until you want to accelerate, so at cruising speed, you are running a 3L naturally aspirated engine.

Is that true? I thought the turbos would be spinning all the time...

It was 100kg lighter - I wish the 335i wasn't so porky

No it's not true. Even with the wastegates open, exhaust pulses are still spinning the turbine. Remember these usually spin around 100,000 rpm under load, and obviously aren't just going to stop once the wastegates are open.

Also, even under very light acceleration the turbos are 'working'...which can be seen/proven by a pre-tb boost gauge.

The idea I believe is that because even a small portion of boost on the highway when changing lanes or accelerating is possible, it is wasted fuel sometimes.

As you might know, boosting 1-2 PSI uses almost double the fuel as opposed to a n/a near full vacuum with good ignition.

So I believe that if you can keep in vacuum and never touch boost EVER, over-time on the highway, you should see a MPG increase.

Some people cant transition off throttle and on throttle without touching a little boost as this car is pretty sensitive. I try to do my best to stay out of boost as much as possible but this car is quite sensitive.

As you might know, the smoothness of the throttle input and the least amount of boost is what is going to yield good MPG at the end of the day. Some people control it better then others.

Ive talked to many people that can barely break 20 MPG average on this car, its not the car its the driver. I yield about 22-23 MPG, driving conservative a majority of the time but having my fair share of WOT a few times a week.

The thing is, how do you not use boost on the 335? Maximum torque is at 1300rpm so the turbos must be boosting even close to idle revs...

saferisk · 09-09-2010, 08:05 PM

Here's hoping to see this sometime soon! *hint hint*

Only when under load.

If you can control your right foot you can stay off boost. I've been doing it for the last 2 days for a little test. I'm seeing ~26mpg city driving over the last 30 miles. Peak recall on boost gauge confirmed car never saw boost.

Papajim · 09-11-2010, 02:24 AM

With the maps changing so easy, now its the time for a valet without boost!
Let's just hope shiv is working on it!

dbjb · 09-11-2010, 11:13 AM

I really like the idea of this for long highway trips or bumper to bumper traffic.

The question would be is this another map that can be switched on/off the fly?
If so, that would be awesome.

I agree, on the fly switching would be extremely useful.

dadgar · 09-11-2010, 08:21 PM

Can Shiv give us an update as to when this will be available for public consumption. It is a great idea and if it gives us an extra 3-4 mpg, I cant wait to start using it. Please have it be a separate map as well because map 0 is great for dealership visits. Thanks.

2 3pair · 09-11-2010, 10:26 PM

I like the idea of this too. I'm curious how it works switching between maps, though. I usually run on map 2, but say I'm headed to work in the morning and switch it to this no-turbo mode, then all of my autotuning in map 2 is lost, right? So every time I switch, the PROcede is having to go through the autotuning process again? Is there a way to avoid this once this feature becomes available?

34 mpg?? Really?? Do you calculate at every fill up? Or is that based on the computer's average?

elim11 · 09-12-2010, 12:22 PM

I would love to see this option also. Now with the autotune completely finished, the car/throttle is ULTRA responsive (which is a good thing). Light applications of the throttle would normally result in rare boost in the past, however now the response time has greatly shortened so boost is "always there"

I've noticed this impacts the MPG on the freeway, as it takes more attention/skill to keep out of boost.
Just my 2cents.

dbjb · 09-12-2010, 01:34 PM

I also commute 90 miles a day, mostly on the highway. If I reset on the highway, I can get 28-29 mpg. Occasionally, I'll hit above 30 buts it's hard to keep it there.

I can only imagine the benefit from switching on/off throughout the commute. I figure once I'm at highway speeds, I don't have the need for 300+hp. IMO, this Procede function is similar to cylinder deactivation. When there's no need for all that horsepower, cut off boost and improve mpg. The gas savings alone make the case for buying a Procede.

Once this gets implemented, I'm switching camps for sure.

Calvin@Vishnu · 09-12-2010, 02:10 PM

I hear rumors of some such stuff being developed right now

Jake@MOTIV · 09-12-2010, 02:18 PM

Wow. I am excited to hit 17mpg a tank

But i do 14 miles each way and its about a 60-90 minute commute on 395 in bumper to bumper the entire way
