<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. I hope to have a
good flowing breather w/ducting to the outside soon. 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?
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? Thanks and sorry this was so long.
