I know that the evo did not meet side impact standards for 2007 that is why they still run 2006's. What I want to know what changes did they make if any at all?

 

Evo X

?

 

I read that non-USDM Evo IXs got a slightly tweaked turbo and ECU map in 2007.

 

Here's the article:

Cliff's Notes:

When variable valve timing was adapted to Mitsubishi's intercooled, turbocharged, DOHC 2.0-liter inline-4 for the 2006 Mitsubishi Evo IX, it became a lot easier to put the power of the famous 4G63 engine to good use in everyday driving. For the 2007 Mitsubishi Evo IX, the peak output of this latest engine calibration remains the same as before at 286 horsepower at 6,500 rpm and the torque rating is also unchanged at 289 pound-feet at 3,500 rpm, but a number of tiny tweaks have delivered the kind of throttle control that pavement racers want.

To begin with, slightly revised turbine and compressor wheels help the turbocharger spool up quicker, building boost lower in the engine's rpm range than before. With a slightly different spark curve and a new fuel delivery profile burned into the engine's electrical control unit, the result is quicker, cleaner throttle response at low rpm plus improved fuel-efficiency.

 

I believe he was referring to the 07 IX. Though was never brought to the U.S because of the crash test ratings?

 

yup thats why they just sold them under 2006 instead of 2007

 

i thought it was cause 07 cars and up needed side impact airbags

 

I'm confused.

 

I'm not sure about elsewhere but in Japan, IX MR was introduced in 2007. Only changes were - 16G to 155G (downsize but supposedly higher flow), Ti-Al turbine wheel with Ti-Mg option, slightly changed MIVEC map, Eibach springs, the rest are pretty much cosmetic.
