Well CPE should have a tuning solution available in a month or so. Here is a link to protege forums, on what they have learned about the speed6 with some useful info about the speed3. It seems the speed3 throttle plate is a problem and they are trying to figure out a way to control it, so the power won't cut out in the higher rpm's. Stupid throttle telling me how fast I can go. Anyway I can't wait until they get the speed 3 on the dyno, to show us what this can do.

I know, I mean we all understood that it was practical to limit boost in 1st/2nd and I think most of us figured we could live with it. But now we find that Mazda was pretty much playing word games. Sure, maybe the wastegate only gets tipped in 1st/2nd, but CP-E puts it on the dyno and finds that throttle reductions in 3rd/4th are effectively limiting boost in those gears also. Per what Mazda told the mags the power limitations above 2nd were only supposed to based on wheel angle. I don't think CP-E had the wheels turned on the dyno, so that's apparently not true. As a new Mazda convert, I had hoped that the stuff I'd heard earlier about their overrating the output of the RX-8 engine and their attempts at bogus viral marketing of the 3 were behind them. I figured that they'd learned it was important to be straight with consumers and gain their trust. Oh, well, I guess I learned my lesson. It's too bad, b/c they have good products so I don't know why they are so afraid to let them stand on their own.

Anyway, I hope CP-E can find a way to deal with these hidden issues. They're saying about a month or so, so it'll probably a couple of months, which is okay by me. That allows more time for them to procure a PnP harness and more time for me to be able to afford the unit when it comes out!

Yeah I don't need it now I just wanted people to know there will be other options soon enough. Do you know if the xede controls the throttle plate?

I would like to know because cpe claims that is what is limited power in the higher rpms.

Alot of information in that post!!!

I want to know more about our car and the "raining parade" now....

I love this comment:
"And truth be told (please don't take offense to this), big horsepower numbers isn't really how we operate at CPE. Obviously horsepower sells, but we're more concerned with the versatility and robustness of the unit. Let me explain. The amount of power one can extract from an engine is pretty much based on your fuel mixture, ignition timing, and boost pressure. How you go about controlling these parameters isn't important as long as they function correctly. In other words, it doesn't matter which tuner you use, so much as what you change. So, we maybe could in theory produce a map for a stock SPEED6 that makes 290hp, but at what cost? Should we increase boost, timing advance, and lean out the mixture just to post good power numbers?

Tuning a car is a black art in that there's no real right answer. We would like to create a base tune for a SPEED6 that makes a lot of power because that's what everyone is here for, but we're going to make sure our tune is safe, but still a lot of fun. If you want to push your car harder than we will, well then have at it and let us know how it goes!"

That is why i have been waiting for CobbAP, now i will wait for CPE also, as they have jumped the Ms6 and already know tons about Ms3, so im sure they will work on it soon

You can see the Throttle % for the MS3 from the AMS data logging post. I even comented about the TP % in regards to the boost pressure:

So, did AMS. It apparently creates a pressure differential that causes the BOV to vent and reduce boost. The unit CP-E is using for the MS3 does have the capability to control the throttle, so they should be able to get a handle on it. The unit for the MS6 is apparently not able to do this, so they have to rig up some solenoids or something. Less of an issue for the 6, though. http://www.msprotege.com/forum/showpost.php?p=2944313&postcount=22
