hello
well iv tuned a car, and saved several maps while tuning it,
when i disconnected the laptop from the s300 and left the costumer he wasn't able to restart the car, i returned to the car with the laptop. uploaded the last map again, and it will start only one time while i'm connected to the s300, while i dissconect the laptop the car wont restart again, only after i will upload a different map start it on the different map, upload the last map again and so on.....
eventualy i didnt understand why the car didnt start, i copied the fuel and ign maps to the last skl that will start the car, and let the costumer go,
after that, i compared the last file and the file before that and suddanly i see that the parameter securitytpsenabled is ON, on the last file, but i never turned it on!!! what could cause this ?

 

I have tuned hundreds of cars on Hondata s300 & have yet to see security parameters randomly turn on.

Perhaps the customer had someone mess with the vehicle & didn't tell you about it etc..

 

he didnt mess with it,
i finished tuning, disconnected the laptop, and left the car, while i was walking away he tried to start and it didnt start,
