How do I reset the ECU?

[dorin]

I was thinking of trying to experiment with different octane gas and I'd like to reset the ECU in order to get a good feel of what's going one. How do I do it? (Dave, any hints?)<BR>

Hello, sorry i aint dave but i got an answer..<P> If you disonnect the battery for about ten minutes or so that should do it.. Some say to do it overnight but I think thats a little on the long side.... <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by dorin:<BR><B>I was thinking of trying to experiment with different octane gas and I'd like to reset the ECU in order to get a good feel of what's going one.

Even easier than that:<P>Pull the fuse marked BTN in the main fuse box under the hood and then step on the brakes for about 15 seconds.<BR>Then put the fuse back in.<P>That's it.<P>------------------<BR><B>Jeff Abrams</B><BR> jeff@mazdamaniac.com <P><B>SUPERCHARGED</B> 2.5 liter 1993 Mazda MX-3 GS <BR> <A HREF="http://www.mazdamaniac.com" TARGET=_blank>http://www.mazdamaniac.com</A> <BR>Normally aspirated 1997 Mazda MX-5 Miata
