As the title states. I'd like to have a spare so that I can have a couple different tunes to compare back to back on a local dyno day coming up in May.

Do you have a plan for defeating the immobilizer?

I have a second ECU and am pretty sure I know how to do it, but it involves copying the EEPROM and I haven't gotten around to messing with it.

^^^^^^^ Ditto this.

I have two ECUs that are interchangeable.

Be sure you start out with stock ECUs too. Certain tuners will lock their code to the serial eeprom.

In short, if you buy a tuned ECU and want to get it to work with your car, the dealer can't do it, as it changes the SKC code.
