Get ‘Tokyo Tuned’...
Tokyo Motorsports can remap your Evo’s factory ECU.
Nowadays there is almost no need to buy expensive aftermarket ECUs, and then have them tuned, unless you need functions such as Nitrous control, sophisticated launch control or some other specific motorsport feature. The stock Evo ECU is an incredibly powerful piece of hardware which is capable of being fully remapped allowing you to optimise the potential power gains of your cars’ modifications.
Mitsubishi spent millions of dollars researching and developing the stock ECU. They also spent thousands of hours perfecting the program that gives the Evo all of its excellent driveability and reliability characteristics.When you remove the stock ECU you remove all of this R&D and some extremely well refined functions such as closed loop lambda control (which gives you great fuel economy) and a knock control system which is unparalleled in accuracy (which can literally save your engine from sudden death due to a bad batch of fuel).
Our advice is: ‘Retain the stock ECU and get it Tokyo Tuned’
The stock ‘tune’ in your ECU is very conservative and allows for some good gains in power with a simple remap. Once your modification list goes beyond a catback and air intake you should be considering a remap. Each remap is written specifically for your car and during the process we typically adjust the High and Low Octane fuel maps, High and Low Octane ignition maps, speed cut, boost cut and MIVEC. The Evo 10 is a more complex process as they include boost pressure maps, torque limiters and dual MIVEC.
There are a number of different systems that can be used to remap the stock ECU. Some well know names are; ECUTEK, VERSO and OPENECU. While different in functionality they are all built on similar technology and the end result is more-or-less the same; the program in your stock ECU will be changed to give your car more power.
The software we use to remap your stock ECU is OPENECU, the Dyno we use to remap your stock ECU is our four wheel drive Dynapack Dyno.
Evo 5 - 9 from $770
Evo 10 from $880
(Please note: Some Evo 6.5 TME ECU’s cannot be remapped due to a problem with a specific memory module. Please contact us for more details).
