The firmware on it in the first place was incorrect so I found a firmware download from A older post and it worked and the car ran. Do you have the right firmware so I can reflash it to fix all this.

those units tend to use custom firmware written by Rev himself.

BUT if you're going to flash it, you need to select the 3. microsquirt (including DIYPNP) option and not the typical ms2 option.

Reflash using whatever firmware you used. When asked which ECU variant you have, choose 3.

Ok so I reflashed it to the right firmware and loaded up my settings from before i reflashed it and now it won't start.
I get a signature do not match and when I load it i get aot lot of errors, the car cranks but does not start and ithe says not rpm synced.
