Just a curious idea... Could the CZ ECU mod by any chance change when the air ducts open? I mean, could we possibly achieve a "turbocharging" effect by just opening all valves roughly @ 5000 RPM's? The only problem I find with this idea would be that you would drastically lose power for roughly 500 RPM, but then have a huge flying curve of power. Also, I'm no engineer so I wouldn't even know if you could possibly change when the valves open.
Just an idea, maybe I'm not yet fully understanding the basics of this problems to comment on it yet...

If you did that I think you would have to stagger the valves like one at 4.8k, one at 5k, and one at 5.2k. I would have to look at the dyno charts for the real lag time after the port was opened. That should really decrease the loss of power. With your solution though at least you wouldn't have to worry about hitting the 2nd port in 6th gear on the highway.

Sounds awesome. I didn't know they had come out with a new re-flash....? Does this one alter a/f maps like the "L" re-flash?
I'll be interested in seeing your dyno's, too, Canz, specifically because I have the SP2. :D

There is yet another flash out this week.
I am going to the dealers to have it done Thursday, and after that we will data log, tune as needed, and so on.
I am planning some dyno sessions next week, as we are testing our maps for the new flash, plus ones for the various combinations of our midpipe, and with the Greddy SP2 cat-back.
So, about a week from now I should have some dyno runs to post.

Got the flash updates done last Thursday.
Turns out there is no "M" flash. This flash just included some regional updates, and a couple of minor fixes for small bugs.
No change to things that affect power or mileage.
