Hello everyone.

I understood that MHD clears the engine code for running a catless set up, which I liked because ofc I don't want to see an engine light on my dash, but if a different engine code were to throw a fault, is that supposed to show up on the dash?

For example, I haven't had a single engine light appear after tuning MHD, but I run the code reader through MHD occasionally and once and a while there would have been a code, one for a misfire and another for my fan.

I'm concerned because I would want to be notified if an engine code would throw a fault other than being catless, but not constantly have to check with a code reader just to see that.

Thanks for any help
