MHD N54 and Smog Help

Vicious · 02-03-2017, 03:34 PM

Hey all,

So i've been running MHD 7.1 stage 1 tune. I reverted to stock tune to get smogged, but it failed three tests (Evap, Catalyst, and O2 sensor). Guy told me to put some miles on it, so I put 150 miles on the car before going to retest. However, when they tested, it failed due to O2 sensor and Cat sensor not working. (Evap was registered by that time.)

He suggested putting more miles on the car. Any ideas why it's failing?

Thanks,
