Ever since I swapped over to the off-road H, it has been really noticeable that the car is running rich. We're not talking the typical exhaust smell that you get when you're running a catless mid-pipe...it's really rich and seems to be getting worse. I'm not sure if it has been this way ever since I started running my Brenspeed tune and the cats were burning most of it off, or if it has just started. I met up with my brother last night who is a Ford master tech and he was amazed at how bad it was.
I emailed Brenspeed this morning and told them what was going on and asked if I could email them a data-log and have them take care of any adjustments that need to be made. This is the response that I got:
I am certain the car is NOT running rich. All AF adjustments are made and controlled by the ECM based off of O2 sensor readings. Eliminating the catts will cause the emissions of the car to be much more easily smelled. The catts are in place to filter out those things and when you remove them all the emissions are just sent straight out the tailpipes. A/F is completely dictated through the ECM and makes it's own adjustments based on the O2 sensor readings.
Any suggestions? If this is the case I'm assuming that I should try cleaning up the MAF sensor and resetting the computer.
