BMAN1113 Posted October 5, 2004 Share Posted October 5, 2004 About four years ago I had an Acura Legend. Over the years it had become increasingly sluggish, etc. I spoke with an Acura mechanic who recommended unplugging the negative battery terminal overnight. He said that it sort of refreshed or rebooted the brain of the car. I was pleased to find that it did improve the way the car performed. Have you all ever heard of doing this with the SC400. I wasnt sure if that was just something unique to the Acura or if this would be beneficial to all cars. Could this do any harm to the SC400?

jbarhorst2 Posted October 6, 2004 Share Posted October 6, 2004 You should be fine, and yes you will probably notice a difference. When you disconnect the battery you erase the computer's memory. The car then has to relearn everything and during that time the performance will be different. Quote Link to comment Share on other sites More sharing options...
JDOwen2 Posted October 6, 2004 Share Posted October 6, 2004 Or you could pull the fuse for the ECU. Quote Link to comment Share on other sites More sharing options...
TMaxxTim Posted October 6, 2004 Share Posted October 6, 2004 Does this work on a 5spd too, or does it not really affect anything? Quote Link to comment Share on other sites More sharing options...
sc_toy Posted October 6, 2004 Share Posted October 6, 2004 This isn't really nessesary... All you're doing is making the car relearn. It will be slower (I have the time slips to prove it), until it learns how to perform again. Best thing to do is just drive it at WOT in various temps to teach it how to make the best power. When I went to the strip, I got an O2 code on the way down, so when I got there I pulled the EFI fuse. First run was in the 16's, and every run dropped about .3 seconds after that (back to back runs) until it hit 15.420 in stock condition. The computer is always learning, so just drive the way you want to drive, and it'll learn how to adjust to you. My car was a turtle when I picked it up, after a couple hours she was a rocket ship. :D Aaron Quote Link to comment Share on other sites More sharing options...
soarer479 Posted October 6, 2004 Share Posted October 6, 2004 well there is also a little trick where you disconnect your battery then run your car hard for awhile till it relearns every thing and supposidly it makes your car a little faster once its all said and done Quote Link to comment Share on other sites More sharing options...
SC4Million Posted October 6, 2004 Share Posted October 6, 2004 I personaly would not. I just did this mod and acctually lost some low end torque, and did not see any power gains. your best bet is to do as above, just drive the car hard...and it will lean to run hard.
