New Guy with TPS failure Code - Help
 

I picked up a 2005 C50 in decent shape for $1200 but it has an FI error code.
I shorted the dealer diagnostic plug and got a C29 code. I replaced the TPS with a used one but the error code is still there. I triple checked the connections. How do I make this go away? The bike starts and runs although it's not terribly smooth (a little jerky) at low speeds. Should I unplug the ECM?

Help me here, I don't know what to do and I want to avoid going to the stealership.
