Misfire on cylinder#2 5/5

Sent my ECU in for assessment for a misfire in cylinder #2. I was kept up to date with progress. and was informed the ECU needed repair. ECU fixed and returned promptly. The fault is now fixed and the car runs well. Would recommend this process if you believe ECU is at fault or you have exhausted all other options.
