'Odd' engine noises after replacing battery?
Perhaps I'm just being oversensitive here... Praying something doesn't go wrong with my SVX and I'm creating boogiemen.
However, I just swapped out the battery today and the engine seems to have a different sound to it now... She idles so quietly it's difficult to tell it's running over the ambient noise outside, but it just seems... Different somehow, when driving. I think I read somewhere that the ECU gets reset when you cut power to the car? Do I need to do something? Will it auto-adjust? Am I just seeing phantasms and being a hypochondriac? Keep it mind I also have an ECUTune 1 v.3. As always... Any advice is appreciated.

It's not a specific noise, persay.. The engine just seems to 'purr' different at typical driving RPM's. ...and again.. I could just be making problems where there are none.. Listening more closely than I had before or expecting to hear something different.

Strange noises aside, you should upgrade that ECUtune chip to v4. Preceding the performance enhancements, wasn't there a "bug" in the code? Upgrading now could rule out any troubleshooting factors in the future.
BTW, I believe that the upgrade is free for v3 owners... It's either v3 or v2. I can't quite remember. Last edited by deruvian; 12-28-2004 at 10:27 PM. |

I believe you are hearing a slight change in engine sound... but thats just because, like you said, when you take the battery out, the ECU clears its memory (depending on how long without a battery it sat) this will give you a slightly different fuel/timing map at first. so it may sound a bit different before the ECU re-learns your driving habits, and "best" maps.
basically. yes it sounds different, but i realllly don't think its anything to worry about.
