Yes.
The GSR ECU can be chipped to run an LS program, but you'd be better off trading someone for an LS ECU and some cash. The GSR ECU is worth roughly twice as much (street value) as an LS ECU..
Or you could throw a VTEC head/intake manifold on it and get the ECU chipped to disable the knock sensor (and be able to be tuned!).
