Tuning......Oh boy what a learning curve

Ok i think i finally did somthing right. Was playing with the BPC vs egr% and whatever i did to that, if i changed it, would cause the car to barley run if i lowered it. Not sure if thats the bpc i was supposed to be playing with, so i went to the injector constant and put that at 19 (as they are 19# injectors) and woahhh super lean. So i dropped it down to 15.5 and it ran a whackload better around town. Wot for whatver reason seems alot weaker, but im sure thats because the PE afr tables are jacked and im sure its pig rich. Anyways blms were around the 120's at least most of the time, but throttle response and general drivability is much better. Heres a couple logs and my current bin lol not much but im learning i guess

that injector constant dosen't do anything.

your BPC should be around 190 for 19lb/hr injectors.

I'd start over from scratch, set the BPC and leave it alone... then make sure "Idle BPW as a function of airflow" is unchecked (constant, Address 06BF, Bit 2) if it's not mapped in your .xdf.. (it's enabled in your posted bin)

then work on the VE tables.. and give it a few more degrees of spark advance.

Im suing your xdf that you posted in the sticky. And i noticed a very noticable change when changing the injector constants. idk maybe im crazy. im gonna dyno it this weekend and see what the hell is going on. Should i set the extended spark slope to 2* or somthing? im not sure what that does, but i would like some more advance right on top. The car feels great north of 6k, just gotta get this fueling down.....They are ford grey tops out of a 5.0 running a pre 99 regulator, but ive heard these may actually be 14 lbs injectors. I have a set f yellow top accels im thinkin about swapping in, i know they are for sure 19 lbs

that extended slope can be very dangerous.. I was told by a very smart man to leave it alone. Mine is set to 0.

I'll update the posted .xdf tonight to include a few other things.
