Description

This design is loosly based on pazi's design but made custom for the corolla 4EFE DIS (that is the engine moidel wich has thetwo coils on it's side instead of the classic distributor found on most starlets 4EFE's) it SHOULD fit inside the original ecu casing but it hasn't been tested nor has it even been produced yet! Feel free to tell me anything wrong with this design as it's my first ever attempt at ecu design!
