Evo 5 rallycar: Can I replace my GEMS ECU with an OEM ECU?
Posted: Sat Sep 20, 2014 10:34 am
Hi
I am new to Evos, and pretty new to engine management systems. I recently bought a -98 Evo 5 RS rallycar. Left hand drive and in pretty good shape. It is currently mapped for racefuel and runs very well, allthough pretty rich. But I assume that is quite normal for a rally car built for going full throttle through the woods. I would like to have it registered for road use. That means I need to put it back to stock to get it approved by the Norwegian road/car authorities.
I took out the ECU last night and opened it up. A yellow sticker on the eeprom inside says LANCER7 G2.41.
I would like to keep the GEMS ECU for later trackday use.
Is it possible to buy a JDM original and unmodified ECU from an EVO 5 or 6 at the breakers yard, plug it in, replace racefuel with ordinary fuel and make it run like stock?
If not, what else needs to be done?
Thanks in advance.
