1st burn a success

using the ahnt bin i have now a successful stock bin modofied to run my formula :-)
thanks guys

got a smooothish 700rpm idle in gear now and i even managed to get the cruise into the 120;s for blm shocked me lol

i used the ewright chip to calculate my figures from and also factor in the diff in a/f commanded and mazingly kinda got the lower ve roughed in pretty decent

definitely workable with some fine tuning so i am on my way

shaved 3 degress from the whole spark table per grumpy. glenn etc

tweaked the upper lower ve in my highway cruise region(horrible mileage trying to help) and even toyed with timing while in overrun to help correct my non coast down car lol

tweaked the idle spark to about 20degrees in the ecm

and set all of my constant to disable egr , the flag for it etc fan temps

got about 300 pages of posts from here filed and in my binder and using those let me get my first prom(total time modifying 1.5 hrs) a working driveable copy to work with using a stock bin
so anyone new reading this do your homework and know what your car is telling u and u can do it
later
thanks guys
