PERRIN/ECUTEK EVO X ECU reflash, gain 40WHP and 80ft-lbs
The ECUTEK product has been around it the Subaru world for a long time and with the recent release of the EVO X, they were the first to market with and ECU reflash product. Like their other products we are allowed to tune the ECU to its fullest potential.
One a Stage 1 reflash (stock EVO X) we can get significant power gains by increasing boost, and maximizing fueling and timing. These changes net 40WHP and 40-80ft-lbs more torque! All this while significantly reducing the BLACK SMOKE cloud out the back of the car.
The ECUTEK reflash is just that, a reflash of the stock ECU. This is a great way to tune a car as we are changing the maps the ECU uses to run the car, not tricking signals to make more power. Changing the actual maps in the ECU is a much safer way, and accurate way to increase power. We can use the safety features built into the stock ECU to control overboost, or knock or any number of things that keeps your engine happy! There are many behind the scene things ECUTEK does that the end user doesn't see. Their great logging software makes for high resolution data collecting to better build maps for your EVO. Along with clear and concise maps, and great dealer support, this allows us to create safe and powerful maps for the end user.
The only thing is we need your ECU here in our hands to flash it. While this can add to the delay of us making your car faster, it WILL be worth it.

PERRIN ECUTEK Test and Tune
We did our test and tuning a little backwards compared to most people. Since we started with the ECUTEK stuff a little late in the game compared to others, and we started our first test and tune session with our EVO X in stage 3 form. We spent a lot of time playing with the variable cam stuff, and a bunch of tables that most people wouldn't normally mess with. We learned a lot about how the ECU works, and what makes power on the new X. We have taken what we learned and applied it to the Stage 1 tuning.
First off we did our initial tuning with the Unichip and while we did get great results with it, we got even better results with the ECUTEKFlash. Being able to control cams, and do some other mapping and not having to trick the ECU in any way made for a better more powerful EVO. PDXEVO (Chris P) was one of our candidates for helping us outwith proving the Unichip on his stock EVO. We did have it installed and working, but we pulled it off in favor of the ECUTEK flash, then did a whole tuning session on his car.
Like we said, we learning a lot from our Stage 3 tuning and applied this to his Stage 1 car. Just like we found on our Stage 3 EVOX, we gained lots of low end power over the Unichip. Below is the car after we were done tuning it. The overall HP numbers were a little lower(like 5-8WHP) from the Unichip tune, but this was done an 80 degree day, compared to a 64 degree day. So slightly less HP is expected.
I think Chris was pretty happy with his car, and with his new found low end power! And to verify our mapping we have a couple more cars lined up that are bone stock. One of them is another local customer who has been on the verge of selling his EVO because of how slow it is compared to his last car. He bugs us all the time about how, if we don't make his car faster he is just going to sell it! Well we got our hand on his car, and did a few base runs to verify power and torque. Compared to our shop car, and the above X, it made less HP and TQ overall. But again compared to the last day we dynoed an X, its now10-15F hotter(90-95). After a few base runs, and 256 seconds off lashing later, we got virtually the same results as our last stock EVOX. The overall gains were almost exactly the same, but the peak numbers were a little lower. Again this could be from heat, or from a motor with less mileage.
I hope that Tad( the customer) finds his car is now fun to drive and doesn't sell it! Again the biggest change is down low. The difference is so huge that it makes it feel like its got an extra .5L of displacement...........hmmm STI??? Wait, no EVO...
Finally since we have some good dyno data to back up our maps we can better compare the different levels of HP. First and most important one is the different boost curves. This below shows the stock boost curve versus Stage 1 versus Stage 3. We felt 25PSI is safe for Stage 1and 27psi for Stage 3 does just fine. EGT's , knock and air temps are all in place.
And the HP graphs that go with those boost curves...
At this point, its fair to say the EVO X, IS a contender to take over and become a more desired car than the EVO 9. And just likethe EVO 9 and 8, INTAKES DO SCREW WITH THE MAF SIGNAL!!!!!!
WE have been seeing tons of guys putting on filters with no tuning, and even drop in filters that "make 25HP". Well on that note, on a stock,unturned car, I am sure there is gains had by these, but its not because the intake is restrictive! Before we were done with both the above cars, we tried our panel filter and saw the exact same thing, 2-3degrees of knock retard. But the exact same power?? Also they ran a little leaner?? Well the panel filter alone caused a pretty large change to the MAF readings and at the same RPM and boost the ECU thought it was seeing about 5-10% less airflow. IF the ECU was not tuned, this would have leaned it out (making power) and added timing(making power) and ran just fine. But on a tuned ECU, this is not a good idea!! Then add in the cone filter! Forget it! These are sooooofar off, there is no way I would put one on a car that is tuned unless there was a custom map for it. This process will take while and it is something we are working on. The proper way is to make a new MAF curve and this isn't something that can be quickly accomplished on the dyno with the time it takes between flashes. So over the next few weeks,keep an eye on us releasing maps specific to intakes.
That's all for now! If you are ready for a PERRIN mail in EVO X custom flash for you 92 octane or better EVO X, give us a ring!
