Ecu no response

Everything is hooked up and running fine. Manually timed with timing light.

I followed their instructions and was able to get the basic program set up. Engine runs fine, but after the first time I now have no connection from the hand held and the ecu. just get the no ecu response.

trying to check all of the parameters. No response. All the wiring is running and connected properly.

any help would be appreciated.
