with this mod , it will be easier to launch the evo with consistent 60 foot times of less than 2 seconds at the 1/4 mile.
use this mod at your own risk!
the rev limiter acts as a safety device so that evo drivers dont do any unnecessary damage by launching the car too hard.
before mod:
the limiter on a 2005 evo kicks in at 5000 rpms when the car is in gear, clutch depressed, and has no forward momentum

what you need, or what i used
1. phillips screw driver
2. small pair of needle nose pliers
3. 10mm wrench or socket
Step 1:
Disconnect the battery (just the negative side)

Step 2:
Remove this piece that is located below the steering wheel. Behind it is the fuse panel. This hole is what i used 2 look through

I also opened the lower dash (using the phillips screwdriver on the 2 screws), so i could make it easier for me to fit my left hand with the pliers toward the plug that needs to be disconnected.

Step 3:
Locate plug

Step 4:
Disconnect plug
using the phillips screw driver, push up on the white tap that holds the plug in place

while pushing up , pull the plug out using the pliers

Step 5:
just let the plug dangle.

then close up lower dash and reconnect battery

however, this mod does have a strange aftereffect..........
{when shifting at high rpms, the rpms will drop much slower than before}
example: Both of these videos are while accelerating in 2nd gear and then i fully depress the clutch. The second video doesnt look like it, but the clutch was fully depressed for the entire time.

so after you do this mod, your evo will act a little different. this is a normal occurrence for evos with this mod. just be advised that it will happen and dont freak out when it does
now this slow rpm drop can be either a good or bad thing. depending on how you look at it.
Good -makes rev matching easier
Bad -when coasting in gear it will feel like you still have your foot on the gas.
-making it more difficult to slow down before a turn. especially on a road course
Finally, this mod can be easily reversed by simply disconnecting the battery and reinstalling the plug
