My tuner just called to give an update on everything, and I brought this up to him. He said in most tunes you are right, which is why he bypasses a few things to avoid it from appearing. Apologies for not having more specific description of what he is specifically bypassing. He was talking quickly and throwing around a lot of terminology.I do not believe an ECU flash eliminates the record of the tune being done. If their is a major engine problem and hey look at the history you do risk Maserati blaming the tune whether you reflashed it or not. Since you are changing their recommended tune you would need to show the tune didn't cause the issue. It is why people have tried the plug ins instead, since it doesn't change the original tune.
