<DIV><FONT size=2>I'm just mentally mapping out the process I'll be using
to get the right prom setup for my crossfire.</FONT></DIV>
<DIV><FONT size=2>Some trucks using the 747 were non feed back. I have both a
vacuum gauge and Air/Fuel ratio gauge in the dash.</FONT></DIV>
<DIV><FONT size=2>Tuning would seem to be a lot easier if the O2 didn't keep
swinging due to feedback adjustment. How does the non feed back setup
differ from the rest? Can I just get a prom from a non feed back vehicle,
tweak the settings where I want, and then burn those numbers into a feed back
style prom? What am I missing? It just seems that for idle and steady
state cruise conditions it would be easier to narrow down your numbers and get
them right this way and then turn the feed back on to compensate for
altitude/temp etc. </FONT></DIV></BLOCKQUOTE></BODY></HTML>
