Hmmm speaking of gas, seeing the very rich looking AFR, I wonder what E85 conversion can do...and what would happen with E85+supercharger :O

EDIT: actually I just looked back at the AFR, and I think it tells some of the story. AFR is going up in the torque dip range, which means it's a volumetric efficiency issue I think, so the intake tuning theory sounds plausible (Subaru boxer engines all have a manifold like that, makes sense that they'd all see the same drop like that). Below 3000rpm it runs quite rich, that looks like the extra fuel they're using to combat the internal EGR effect of advancing the intake cams. The high end being so rich is a mystery though...

This is true, but it does take away from the numbers, and though you should never compare numbers between different dynos, people do it all the time anyway, and comparing numbers between an AWD and 2WD dyno is even worse, haha.

So, no 93 gas in Oregon? Why would you dyno a car not on gas required for top performance?

Because it's a realistic street spec dyno?

Below 3000 it goes lean. Rich is lower, lean is higher on that graph.

I take it you're gonna be filling it with 92?

Um, I know that, and below 3000 the AFR is lower than it is between 3500 and 4500 or wherever the "torque dip" is at.

with the ECU being open, its just a matter of time before a free maps end up here on the forums, cracking an ECU is no longer required so the cost is not justified, I can see ECU maps floating around for free or less then 50$ with AFR, and a good map, super chagers and turbos should be a snap.

EDIT: I am wrong. Interesting that they would want 93, I've never seen anything from Toyota require 93.

Jeff

The manual actually says 93 is recommended, 91 is fine but may have slightly decreased performance.

Yes I see that now.

Jeff

I'm shocked nobody's mentioned it yet but:

WHAT KIND OF DYNO ARE THEY USING?

That makes a bit of difference when you compare it to other people's dynos. Also the altitude/air density would be useful to know, too.

Agreed, that information is good to know, along with knowing if they are corrected or uncorrected values.

Jeff

Lol, I just realized this....


Never mind, I'm glad I went to the auto show...
