ProECU Tools are EcuTek's ECU reprogramming software for the 1999 model year onwards turbocharged Subaru and Mitsubishi vehicles. The software allows reprogramming of the original ECU, in-situ via the diagnostics port, along with serious features that allow accurate and successful mapping.
ProECU Tools have been designed with the professional tuner in mind. Those familiar with engine management will find the software intuitive, and a pleasure to use. Written by tuners for tuners, ProECU Tools is the software that we at EcuTek use to produce our performance ECUs.
This product is available to the commercial tuner only and is not supplied to individuals

Four ProECU Tools are available, supporting four different Subaru and Mitsubishi ECU architectures. The first tool (Flash99) supports the 1999 and 2000 model years of cars. The second tool (Flash2002) supports the 2001 to 2004 model year of Impreza WRX and STI. The third tool (Flash2004) supports the emerging range of fly-by-wire ECUs, as seen in the US STI. The fourth tool (FlashEVO) supports the legendary Mitsubishi 5/6/7/8 range of vehicles.
The current list of supported cars is as follows:
The list of supported ECU for Flash99 is shown below. This list is constantly being updated:

To reprogram the ECU, the EcuTek programming interface is simply plugged into the diagnostic socket of the car. Any of the ECUs listed above can then be reprogrammed in under 2 minutes !
Unlike other 'chipping' solutions, ProECU Tools, require no soldering and no physical access to the ECU - an altogether quicker, cleaner and more reliable method of tuning. Rather than spending time soldering and desoldering hair thin chip legs, the tuner's time can now be spent more productively, with less time spent soldering and more time actually improving mapping of the customer's car.
Once an effective map has been produced for a particular combination of modifications, further identically mapped ECUs may be rapidly produced. This is extremely useful for companies who wish to package a premapped ECU with their exhaust manifolds or turbo/FMIC kits.
The following ECU parameters may be altered using ProECU Tools:
Both ignition and fuelling maps may be viewed graphically to fast interpretation of map shape. This also allows errors to be quickly spotted. The example below shows a fuel map that is being viewed graphically, to show the spectrum of air/fuel ratios used by this ECU.
Whilst testing the car, either on the road or dyno, access to fuelling, ignition and boost maps may be viewed in real time to show which parts of the map are being accessed by the ECU. ProECU Tools will also colour the zones of the fuelling or ignition maps based on the knock correction and lambda values retrieved from the car under test. This allows the tuner to quickly see which areas of the map require attention.

Below is a dyno plot from a UK 2002 WRX with standard induction, turbo and intercooler. The exhaust has been improved and the ECU remapped to provide 60 BHP more power at high revs, as well as very useful mid-range torque gains.
