Some ECU's have a flash counter that let dealers know how many if any, times that the ECU has been flash tuned. The mustangs and focus rs have them and I'm pretty sure the evo x does. Just wanted to be sure. Just don't want them to see that it has been flashed about 50 times.
I could not see anything in the Data lists about rewrites being recorded. I will try to have a look on a live vehicle tomorrow. I have got a new MR Triton coming in with a trans issue.
