subiru66 Posted July 19, 2023 Report Share Posted July 19, 2023 Hello Link Community, I recently purchased a G4X WRX11 ECU for my 2008 STI Hatch. I am beginning the arduous process of installing and tuning on an extensively modified vehicle. Sufficient to say, I am nowhere near a tuner or a dyno, therefore I have to handle this process myself. I noticed that basemaps are supplied with this unit but I dont see a V11 WRX map for the STI. The supplied maps seem to be just for the 2.0L WRX. Is the expectation I use this as a starting point or is there indeed a starting map for the 2.5L WRX STI ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 20, 2023 Report Share Posted July 20, 2023 Our test car which the maps came from is a JDM sti which use the better 2.0 engine. The maps use modelled fuel equation so just change the engine capacity and injector size and it will run. Some of the 2.5L also have a different MAP sensor calibration so confirm that reads correct and you shouldn't need much work to make it drivable.
