With just over 1,000 miles on the odometer, my wife and I took her EVO IX SE to have it custom tuned and dyno'd. Aside from this custom tune, the car is bone stock. Here are the dyno graphs:




The green line represents the baseline numbers, while the red and blue lines represent the results of the custom ECU tuning (back to back runs). The timing and fuel maps were altered, the cam angles were changed, the fuel cutoff was increased by a few hundred RPMs, and the launcher limiter (don't know the exact term) of 5500 RPMs was eliminated. The butt dyno tells you there is a distinct difference from this tune alone. Big props to Shawn Church!

The next performance mods will consist of the following: AMS 3" down-pipe, AMS 3" test-pipe, AMS 3" TBE, and Hallman MBC. The car will be retuned (probably up to 22 psi or so) once these items have been installed.

Note: Let's please not talk about the type of dyno this was done on. We all know that dynapacks read higher than dynojets and there is no need to start any arguments here. Instead of focusing on the dyno itself, let's focus on the results from the custom ECU tuning: an increase of 23awhp and 26ft-lbs at the same boost levels.

 

Good deal, what did you use to tune?

Also that's crazy, I had no idea Evos ran that much boost stock!

 

Shawn had some program on his laptop that he used.

 

i think the question was asking for a type of engine management

 

Understood. There is no aftermarket engine management system. The stock ECU was reflashed with the custom tune.

 

noice!!!!

 

I want my wife to drive an Evo... the day that I do get a wife that is

 

 

Nice improvement from a bone stock car. Evos are fun
