ring damo at streetperformance there is a load of different ecu to choose from i think damo has mapping dates coming up in febuary, get it mapped asap, take it handy until then here is info on simtek ecu
The SimTek is a full Plug and Play MAP Based ECU for 1993 - 2006 Impreza and has excellent features complete idle control , Antilag , Launch Control , Full Closed Loop Boost Bontrol , Water Injection Control Switchable Maps for different Fuels or hi low boost , full charge temp compensation and the list goes on and on. This system will out perform many of its competitors which are at least twice the price in both functions and control.
Future Developments will include a small display device similar to the Apexi Commander.
The knock Detection Circuit is fully digital processing and indicates which cylinder is Detting, and rather than having to pull the timing and fueling across the board the SimTec can trim each cylinder for timing and fuel individually.
Flashes CEL light for Knock.
Full plug and play unit which allows you to discard the MAF.
3D boost map means the likes of the ACV-R Boost Controllers are made redundant with the SimTek as there is No Requirement for seperate Electronic Boost Control.
