Tuner Pro RT ECM flashing

[kenh397]

I've decided I'm NOT going to rebuild the 5.7 small block in my 90 C1500. Instead I plan on swapping a LS into it.

My question is... Will Tuner Pro RT directly flash the ECM (OBD II) of choice or do I need another piece of hardware? Looks simple enough to turn off VATS and sensors you don't need. Tuning may be another issue but at least I can get the engine to run.

Thank you!
