hey everyone ive looked around and havent seen anyone place any mpg gains for reseting there ecu, also i havent seen in pictures or info to unplug which particular fuse in your fuse boxe(s) either. Anyone have any info on any LS,GS,IS,ES pictures as well? let me know as i have a 90 ls4 and would love to know the diy for that as that i just purchased my car

 

just disconnect your battery for like 30mins. should be good then.

 

what if i want to use by the fuse method? where would the fuse be located? under the hood or in the cockpit?

 

that i dunno about, just check the covers, it should label what is what. still think dcing the battery is better but i know u just cant lose your radios memory...

 

iirc it is the EFI fuse in the engine compartment (drivers side)

 

If you disconnect the battery you loose all your radio presets and it only has to be for 10seconds aswell.

Here is a picture of the fuse you want to pull in the engine bay, same deal rip it out for 10-15 secs and presto your done and still keep your presets in place.

I always reset my ecu after any kind of modification/parts replacment.
