Stumble on start

Hi, can anybody update X type ECU to cure hot start issue? In Nottingham or Sheffield are?

The car shows no fault codes, I think it’s known as a stumble on start. There was an update to relax the fuel pressure requirements and lash voltage at start up. The fault started immediately after i changed the injectors putting old injectors back in cured the fault immediately, I did reprogram the injectors.

Intrigued…what do you mean when you say you had reprogrammed the injectors…?
