This morning, after thinking about it, I reset the computer, and that seemed to help my issues. Then, I started playing with the timing, reseting the computer after each ajustment.<br /><br />My problem now, is even with conservative timing adjustments I'm getting a little detonation at WOT. At the moment, I don't hear it until I reach 3rd gear, and after a little experimentation this morning, I've settled on 13*, for now. As long as I don't lay into it, I don't hear any pinging.<br /><br />My question is in the threads topic: What I really want to know is, can anyone make a call on what brand of fuel is superior to the others when it comes to detonation. Up to now, I've been running 91 octane ARCO. I realize it's a cheaper brand, but the car has run great on it up to now.<br /><br />My only other engine mods are Steeda's pulleys and a C&L 85mm MAF with their Trueflow pipe.<br /><br />Any suggestions would be welcome.<br /><br />Thanks, <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>saleen00925</b> <br /><small>Member # 1302</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,2,16,10,47,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> all gas is the same, people don't believe me but it's true. they all ship their gas through the same pipelines, they put in a barrel in texas and can take out a barrel in california that probably wasn't theres to begin with.

I saw all these tankers fill up with the same stuff from the same whose even with my very own eyes.

Cheap gas and even Union 76 had all three bikes missing and pinging before I got 5 miles from the station. This was always running Premium. Chevron was the best gas I got, followed by Texaco and Shell. Anything else and the bikes ran like crap. An extra 6 cylinders helps to mask the missing and knocking but bottom line is tune from Chevron, Texaco or Shell and it won't get any better.
