on TMO's guide to removing the ecu it says there are 2 resistors which are used to designate different engines
"Check the ConfigID. There are two configuration-identification resistors. The existence or absence of these resistors let the ECU know things about the engine it will be controlling. In this way, Mitsubishi can build one ECU, solder one of four different resistor combinations in, and re-use that ECU for four different engine packages. These resistors are R129 and R130 (circled in yellow in Figure 5a). Please note whether or not there are resistors soldered in at those two locations."
anybody know the 4 combinations made with 2 resistors? california/49 state and 1.8/2.0L? is it possible to use ecus from different setups if you swap out resistors? i don't need an ecu, but i know some people might be willing to change resistors rather than hunt for different computers.
