Mx5 on ecumaster black

I recently have upgraded my ecu to an ecumaster black.

my engine specs are

bp4w engine fully built bottom end

head has oversize valves and dual springs and titanium retainers and turbo cams.

efr6258 on an equal manifold

skunk2 intake manifold with skunk tb

the problem im having is one the trigger signal in the log is really dirty and having to be filtered alot….. the scope looks clean

and also im getting a missfire from idle to 3200 which i have tried multiple things including change the main cable to the csp aswell.

Hi Ashley, are you using a good shielded cable for the trigger wiring. I have found the classic had some noise if using the flying lead kit and missfires.
