comparing the ez30 ecu to the 2.5i ecu. looks to be a much more complete swap then the eg33
the ez30 will allow me use all my factory fuel tank sensors, and the factory fuel pump controller, speed sensor, coolant temp gauge, fan relay controls, and the factory tach with a converter.
essentially rip out the eg33, install the ez30 merge the same wires i had merged with the eg33, then about 8 - 10 more wires. seems simple enough. now i have to find a good ez30 and harness/ecu
