So the Evo 8 ECU work with the base lancer, as long as the ecu is reflashed and retuned. So would the Evo 9 Mivec work with our Mivec lancers?
Just something to ponder.

Don't think anyones tried. Would prob make it more tuner friendly though

Our ECU has 141 pins the EVO 9 ECU has 100 pins, also the EVO 9 does not have an electronic throttle. If the sensors are compatible however one might say there is a possibility to switch to another throttle and manufacture a plug and play harness to swap the ECUS this might be interesting

Yes, I have looked into the electronic throttle problem, as mine has giving me plenty of problems. I found a universal delete kit, that might be able to adapt.
OR
if we go turbo we may be able to steal the evo throttle/ throttle body set up, and since we are going turbo may help delete alot of the hassel.
I think I will be contacting my tuner when I get off work.

doesnt one of the galants throttle swap perfectly? and its a wire throttle?

Yes but the EVO computer does not control the throttle YOU DO

I know I'm late to this, but something needs to be made clear - the MIVEC on the Evo != the MIVEC on our car. They operate different and the ECU from one car wouldn't likely be able to control it on the other.
