A question about ECU/Chip tuning
Hello people, I just have some questions regarding ecu/chip tuning.
I spent time searching for it, but couldn't get the answer so I thought I should ask people on this forum.
If you have some knowledge about this topic, please feel free to chime in.
1. I was wondering if it's possible to get CEL after you get the ecu/chip tuning.
2. If you do get the CEL after the tuning, what's the cause of it?
3. If this issue ever happened to you or someone you know.
I see that some people write sarcastic or non-related comments, but save that for your boss.......
Also, don't need to write "tuning does not worth the money, don't get tuned, they are not safe, and etc."
I'd greatly appreciated if you guys answer the questions.
Thanks in advance.
