Default Cobb econo mode DYNO'D! (1st ever?)

Got my stage 2 saabaru dyno'd at ALLASPECTS in chesapeake VA.

Took two runs on econo mode (wife's daily driver, she left it in econo and didn't realize it). We were really confused at first, but figured it out in no time.


So heres the dyno






And here's the correct map.

TXS cast uppipe, PDE long downpipe, samco Y-hose, stock catback, stock everything else.

Econo mode rules

On a trip to eastern washington we got just slightly over 27mpg on Econo. Not bad for climbing some mountains, and using the A/C on the way back.

I hit max boost (7 psi) on econo mode going over Snoqualmie pass. Cruise Control set at the speed limit.

The Econo mode is more than just limiting boost, it uses agressive engine timing to get the most fuel mileage possible.

well my buddy with 100k miles on his wrx, stage 2 cobb map, up/downpipe, stromung dual tip catback, power/underdrive pulley, and APS intake made 218whp on that dyno. You can see it here:
http://forums.nasioc.com/forums/show....php?t=1038438


So for his mods, my car did about the same or slightly better.


They still haven't got a stock wrx on it yet. They have only had the dyno for about a week.

It doesn't turn it into a prius, but you can drive it however you want and basically get the same mileage as if you were on a regular map and trying very hard to drive conservatively. Consistent 27/28 mpg on the highway without trying. Not too bad.

Plus you can run lower octane and cheaper gas. So its nice to have.

However, the car feels dogslow in econo mode. How in the wolrd my wife was driving it that way for 3 weeks without realizing it, I just can't figure out.
Made for a very interesting dyno experience though

the new econo map is NOT worth it,... the way it's set up now. The old econo map was WAY better, at least it went to stock boost levels when you put the pedal to the metal. I used to use it fairly often ,... now I can't stand it, this limiting the boost to 7 PSi is not do-able on a "sports" car. You are better off to keep it in stage 2 and just use some restraint ... you "CAN" get the same kind of gas milage... and still have the HP when you "NEED" it.

So you live in the Chesapeake area and haven't posted in the Mid Atlantic Forum where all us locals hang out? Talk to locals buddy, that's where you get all the information. No they don't protune and no one locally does.

I get worse mileage in econo mode than regular stage II. Averaged over 3 tanks of gas each for each map with cruise set on the highway on the same vacation trip. Almost 2 mpg better with the regular map.

If you look at the graphs, the a/f on the stage 2 is actually a little bit leaner. :shrug:


Miy saabaru is the only cobb car on that dyno so far that haven't bottomed out on the A/Fs @10s. Pig rich.

No, you can't, the aggressive timing the economy map runs will get you lots of knock on low octane gas!

I think someone else dyno's the economy map before, but still interesting none-the-less.

What you call gas in cali would get knock here if I tried to use it in my moped


It is designed for at least 91, although I recall something about it taking 89. Both of which would make it cheaper than what normally we run here.

If you search the Cobb forums, you will see a note that while Trey considered tuning an economy low octane map, the end result was that it was more economical to run 91+ with the economy map and the additional timing the higher octane allowed.

If you run 89 it will knock. Try it.

Default Does the crank to wheel hp loss seem right?

I'm new to AWD cars having mainly owned American muscle RWD prior to this, but it seems like ~40% power loss from the crank to the wheels is a bit steep, even more so given the manual tranny. Are these numbers in line with other results people have seen?
