Default Map switching

When I was reflashing, and tuning Suzuki ecu's they had A maps for fuel and ignition. I was able to switch between them by grounding, or un grounding a specific wire going in to the ecu. That was the wires only function. Grounded would be map A for exampe just running on motor, and switch (unground) (switch time aprox 60ms) and your in map B (for a dry shot nos map, more fuel and pulling timing as nos was applied). It worked very seamlessly when configured properly. The early ecus ran the SH7052 chip. I'm shure the Subi ecus have this, but I don't know how to switch between the two. I'm shure somebody out there knows. It would be nice for tuning.
