<DIV><FONT size=2>Hello All, I am new to the list, and so far, the extent of
my knowlege is just knowing how to change to different ECM's and factory and
aftermarket proms. I am just getting started in the programming stuff
and so far, it is very interesting. I just ordered one of the pocket
programmers from the transtronics website. It seemed like a good
programmer for the money. I am running a 1227747 in my S10 Blazer with a
TBI 305. I am interested in modifying my chip for best performance,
however, am going to go about this very slowly, because i don't know much yet
and don't want to smoke anything (engine). One question i have is that i
seem to have excessive detonation unless i run the 93 octane gas, and even
with the 93 octane, i still have a little. I am running a hypertech
stage III, and realize that it advances the timing more, also, i have an open
air cleaner which means that i am getting hot air off the
engine. </FONT></DIV>

<DIV><FONT face="MS Sans Serif">Also, alot less restrictive, and hence leaner
at times.</FONT></DIV>

<DIV><FONT size=2> I hope to have a good flowing breather w/ducting to
the outside soon.</FONT></DIV>

<DIV><FONT face="MS Sans Serif">While seemingly odd, I never really found any
real HP in doing that. At 30 MPH there is alot of air circulating thru
there. So it might help at idle/low speed, IMHO.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> The chip i am running is actually for a TBI
350. Does the ECM advance the timing more than stock under all driving
conditions with the hypertech chip, or just under WOT? </FONT></DIV>

<DIV><FONT face="MS Sans Serif">Hard to say without reading it.
</FONT></DIV>

<DIV><FONT size=2> Just a note, i am also running an ACCEL replacement
ign. set to 0 deg. with the EST disconnected. This is what the
factory recommends for my engine. Any thoughts?</FONT></DIV>

<DIV><FONT face="MS Sans Serif">The 747 is totally hac'd at the ecmguy's
site</FONT></DIV>
<DIV><FONT face="MS Sans Serif">Both Tunercat and Terry Kelly sell editors for
it.</FONT></DIV>
<DIV><FONT face="MS Sans Serif">The 747 is a great ecm to learn
with.</FONT></DIV>

<DIV><FONT size=2> Thanks and sorry this was so long.
