My friend just bought an Evo this last weekend and doing some homework for him I have found that our car isn't the only one programmed with "pig-rich" fuel conditions under boost. I got this information while reading an article on http://www.evolutionm.net
This is a quote from an article on their website in reference to their project Evo: "We've all experienced the amazing surge of power from the 16G twin-scroll turbo as the Evo reaches ~19psi @ 3,500 rpms. It's an amazing jolt that pushes you back into your seat. The problem is, there's not much steam left in her up top and that can really put a damper on things, especially for those of use who enjoy running through the gears or track events, where a smooth, linear powerband is essential.
So why is this the case? Well, in an effort to play it safe, Mitsubishi has designed the ECU to run the Evo extremely rich for knock suppression... somewhere in the neighborhood of < 9.5:1 in the upper rpms! Most a/f meters won't even register the number because it's off the scale rich. The good news is that with a few small modifications and careful tuning, there's a decent amount of whp that can be safely extracted."
It goes on to say that they get help from Vishnu Performance to re-program their ECU and/or use a piggy to extract maximum power and efficency, blah blah blah and that this was only one of the various upgrade packages available. Vishnu has done this for other cars as well, like the WRX and Miata.
My point is that we need someone like Vishnu to help us out. I know Perf was working on this exact type of thing, but I think I remember him saying that he doesn't have time to do it anymore. We as Mazdaspeed owners should all contact companies like this and request that they do this for our car. I have to believe that if there is enough requests for this, something might budge. What do you guys think?
