Diesel engines use fuel delivery to change engine speed. In other words, diesel engines have no throttle plate, and instead use the amount of diesel fuel thats being injected in order to regulate engine output. Gasoline engines, like the one in the MazdaSPEED vehicles use an air throttle to adjust engine output. So if engine output is regulated by the throttle, then you would surely want full control over it, right?

Mazda released the MazdaSPEED vehicles with their implementation of Fly by wire. This electronic throttle technology was intended to improve throttle precision, reduce emissions, and can also be easily integrated into advanced electronic stability control systems. Great right? Well, the auto manufacturers dirty little secret is the fact that an electronic throttle can also be used as a power governor. Since the driver is no longer mechanically linked to the throttle plate, the computer can put the throttle position wherever it decides. In other words, even if you have your foot to the floor and you think the engine is giving all its got, the computer never really opens the throttle plate to 100%. No kidding. Take a look at the throttle position graph to the right. The blue line is the stock throttle mapping on a SPEED3, and the red line indicates the throttle position after the flash.

We call our flash FullControl because it does exactly what the name implies: It gives you, the driver, the customer, the enthusiast, full control over engine output. Our FullControl flash optimizes the throttle mapping so that normal cruising is unaffected, but when you floor it, the throttle plate travels to a true 90. That way you can reap all the benefits of an electronic throttle, but now without any of the drawbacks. Normal throttle operation is as smooth as it was from the factory, but when you smash the go-pedal the mid-range torque curve swells considerably, and top-end breathing is also greatly improved. So take the gag off that otherwise potent turbo MZR, and enjoy it the way it should have come from the factory!

Looks promising. Intro price is right. The downside is you have to take the ECU out and send it in. That's a no-go for me since it's my daily driver and can't go without a car for 2 days. They don't give details on what is done to the car other than the reflash. Obviously at 272whp before reflash, this is not a stock MS3. Gains are great at 4300rpm (over 50whp).
 
Wow, great work! I gotta get this flash!! Does seem high at $400 for a flash, but we gotta think about the time that went into developing this.

Swampass, any drawbacks to the flash?

Got me. I just saw it listed.

I live close enough to have it done if they can do it that way.
 
F the dyno numbers just think of the difference it will make in first, and second taking corners
 
Sucks the powerband still tapers off up past 5500 even with the throttle plate wide open.

They've just proved what Cobb has said all along, that opening the throttle 100% wont give you power to redline (on a stock turbo).

I would like to know whats parts are on that car though as it certainly isn't stock.
 
I was just at the dealer recently and asked why the engine basically shuts down after 5500rpm and the mechanic couldn't tell me why other than "thats how the car is programed" so I'm wondering if mazda did it for fuel economy or some other dumb reason.

The only gains are in the mid-range where the throttle plate isn't the issue. Looks like a nice tune and that's about it.

I'm pretty sure at 5500rpms no one is thinking about fuel economy! I think someone said something about the engine not being able to handle that much power that high in the rpm range.....

I'm getting sick of this, too much boost down low will blow your motor, too much power up high will blow your motor, more than 300whp will blow your motor. Do I just need to upgrade pistons and rods now before I go any further?!?!

That may have been too technical of a question for the tech at your dealer. These are the places still putting 5W-20 in this car.

Has anyone thought maybe it's the cams? These cams may not have enough lift at high RPM to support the flow. This motor has variable valve timing, but does it use the same concept as Honda's VTEC with two sets of cam lobes? I had thought it just adjusted cam timing.

Out VVT is similar to the one Toyota uses. We do not use VTEC, there is no second cams.

I doubt its the cams, you have to look at the dynos from people who have another turbo.


Now as for a bit of proof. Here is Whoosh (a MS6 owner from another forum who is running a bigger turbo and rods + pistons & a few bolt ons. He just got the car tunned and is hitting near 400whp, hes waiting to get his car dynoed again. the 400 is an estimate based on how much power he is running right now.)

Notice how hes making power up to 6k? I am not sure if these are the best dynos to show, because it seems that he hes stopping at 6kish rather than trying to go to redline, but its starting to improve
 
maybe the turbo can't move the air required to sustain high RPM power.

that's right, turbos dog out at higher rpms anyway. twin turbo setups do better with full rpm range power.

it really does stink how this engine doesn't have all the aftermarket companies jumping at it with all sorts of internals, etc. you open up one import mag and you'll see upgrades for anything (rear view mirrors to piston rings), as long as it's a honda, vw, nissan, blah blah blah.

i'd keep going but i dont' want to rant too much
