I have started having a prob with my trudo80 , ever since i used the data lead to download settings from my fadec , I am getting the failed start error stating " Bad Start " the starter is running up to 18200 rpm , what I have noticed is that the gas apears to come on and ignite as soon as the starter kicks in .. before it used to spin in a number of bursts and add the gas ... is it possible I have currupted the settings in the fadec ? if so , is it possible to reset to factory setting using the handhelt data terminal without connecting to the laptop ? or can you sugest any other fix ...
its cold out here , so I have tried starting in the workshop with a room temp of about 24 c . so no probs with gas flow ect , I have also tried starting with a external battery pack to rule out a bad cell dropping on start up .

many thanks in advance
