Does aftermarket Catback Exhaust require computer reset?
I have read that if you install an engine-back exhaust you should disconnect the battery for 30 minutes to allow the the computer to adjust to the new system. Should I also do the same for just an install of a catback muffler? Its a Topspeed on a 2002 S.
Thanks in advanced. :cheers: |

Any engine will make more power when operated in colder more dense air compared to hotter and more dry air. Air inlet temps are a determining factor to engine output, just like humidity and elevation, all things combined create the relative air density.
From what we have noted, the Motronic ECU is VERY SMART and can compensate and "Learn" alot without reprogramming or flashing. I have seen much bigger engine changes than an exhaust with no need to reflash the ECU... More power might be made, and it might not... Bolt on the exhaust and see what it does. |
Ok, so I bolted on the exhaust and went for a run. It sounds amazing, with just a little bit of resonance only when I punch it while I am in the 2k to 3k range. If I am just giving an even amount of throttle in that range, I really dont hear any. It does seem like the car is a little bit slower and not as responsive. I am going to run it for a week or so and see if the computer adjusts. If I dont notice a difference, I will reset the computer and see if it can adjust to the new changes. Has anyone else noticed this?
