brett_xr6 Member 61 Member For: 16y 11m 20d Posted 09/10/08 02:00 AM Share Posted 09/10/08 02:00 AM Hi,I have a BF XR6 and have fitted a complete Herrod Exhaust system on the car including headers and high flow cat. Before my car went in for the system the engine light was on due to failure of the old cat. Since the new system the light has gone away and the car has not been custom tuned. Given that its a BF is it odd that the engine light has not come on and put the car in limp home mode, as I have probably driven a good 500kms or so now?Cheers Brett.

Guest Guests Posted 09/10/08 02:11 AM Share Posted 09/10/08 02:11 AM Is it a XR6 NA or a turbo?It will only go into limp mode on a T if the exhaust flow is dramatically increased allowing overboost, which in turn makes the car shutdown to protect components. A NA wont go into limp mode as easy... Link to comment https://www.fordxr6turbo.com/forum/topic/50513-engine-light/#findComment-746817 Share on other sites More sharing options...
brett_xr6 Member 61 Member For: 16y 11m 20d Posted 09/10/08 10:24 AM Author Share Posted 09/10/08 10:24 AM Yeah its an NA. That does make sense with the turbo versions. I spoke to my Ford Dealership who said that given it was a Herrod system it may or may not come on.
