my truck did that one time and it was just a loose clamp on the intake piping

it runs 28* at wot with no knock, is that bad

the chevy dealer charged me $100 flat to flash mine, even though it wasnt the prop, ended up being the aftermarket radio no letting the the predator and ecm talk and i had to take the radio out every time i wanted to tune it so i just rewired it. and i got the same code. i would try unpluging the ...

at 7 i get 26* advanced which seems to be what it likes best

do u have ur stock radio or is it aftermarket

so i dont need af ratio for the program work

know that but i dont have a interface cable right now but will get one soon but even then it only tells u what pe adjustment to make, does i tell u what timing adjustment to make

03 sliverado 5.3

im trying to do some data logging on my u7193 and cant figure out what i need to log to look at a/f ratio

i have a u7193 and am wondering how to adjust the timing and fuel tables to make most power

im using the diablo tune with 93 octane gas, i went to the track and lowered my time by a half a sec off the diablo tune by increasing my timing 6*, i think its degrees, but i ran out of time and didnt get to see how far i could push it

so i need to adjust it and then log. do u know what the timing should be for max performance

on my 03 silverado with the 5.3 how much can i advance the timing safely, and when will i know if its right

i dont have a cable so i cant use the program

i just did some data logging on my u7193, i logged long term fuel trim 1 and 2, question is which one do i look at to adjust my injector slope
