Got a 2007 Trailblazer SS that someone else tried to get off the ground. I know nothing about idle timing and can't really figure out what he done, which has me even more lost. Just wondering if someone could look at my as found and see if anything jumps out to you as to why and what I can do. Thanks
Can you be more specific about what you are asking?
Does it not idle at all or are you asking why won't it chop at idle?
For one the timing is set kinda avg at 22 degrees, that will make it pretty tame if the fueling is on point. The idle rpm is set to 850rpm, which is kinda high depending on camshaft design to make it chop.
More information about what you are asking is needed, or even data logs to show what you are talking about.
Thanks 5FDP, Won't idle at all. Have to pedal to keep running. It's just I don't understand some of the changes this tuner made or why and I'm a little scared to proceed. I know nothing here.Quote:

Man yall fella's get up early in a.m. Thanks Sultan, going to get started.
Flashed and it idles good except, when I rev it up and let off it will die. I'm in process of setting all my timing histo's and such. in scanner. Very new to this "slow" but gaining. Thanks.Quote:

Could you tell me which parameters you need logged. Sorry for late responses, I've been on dyno all day. I have a mustang dyno and it's Friday. All the street boys are wanting pulls. I'll get it up as soon as I can get logged. Thanks again.Quote:
