i can chip both usdm and jdm ecus, i have the stuff to do usdm right now, you have to watch switching from jdm to usdm on a gsr, the iab circuit is reversed on a jdm ecu, if you use a usdm ecu on a jdm motor, best case is the secondarys dont work, worst case is you smoke the ecu, i am only saying because you want to trade a jdm for a usdm

The only difference is the ecu supplies +12V or GND. simply check what the ecu will be supplying to close the circuit, and make sure the IAB solenoid is wired to the other.
