So its my first day attempting to tune, I have attached my log from driving around, and idling at lights, at the end of the drive, I would right click my data, then select SD VE ADJ (CombinedFT). I did this about 4 times before I started this data. This log is the final drive I did before I got home, where I then did it one last time.

Looking to get some sort of nudge in the right direction! I am not sure if my global % and dead time are correct. Also it feels as if the airflow is still off, and my LC1WB is still reading like 16.0+ under 20% throttle (especially noticeable on hills, the car kinda jerks around, and i have to use less throttle and go really slow to make it all the way up). Also I noticed several High numbers in VE table that it was recommending... (like 100+) is this normal? Or is something wrong
 
I would say you need to increase your global fuel by about 5 percent.

actually, thats what I ended up doing. I will post a new log tonight... I think I am getting closer! But the car still doesn't like to go more then 40% throttle, or build more then 5lbs of boost at anytime... Still trying to figure out this stuff! Thanks!
 
Grab a new log. I will try to help out as much as I can. I had to tweak my SD table to get my car to even run so it takes some time and I feel your struggle my friend.

So today I switched back to my stock injectors (pondering if my venom 660ccs were going bad) and I set my global fuel to 0% and my deadtime back to 0, where my car is still running like shit. And the combined ft at idle was like 22%... car was running really high AFR's 18-20

Im starting to think my fuel pump or FPR is going bad....
 
Hmmm... I'll check into it.
Im hoping to pull out my fuel pump tomorrow and see if its the problem. Its just been driving me crazy. I thought if i had put the stock injectors back in, and changed the VE table and global fuel & deadtime all back, that it would all work great. seems not to be though.

How do I tell if my FPR is bad? I read somewhere you could disconnect the vacume line, and if it smelt like gas or gas dripped out, then it was bad, is this true?

Could a fuel pump deliver enough fuel to idle, and light load, but hit a stopping point? It's not making any new noises or anything. Could perhaps I test the voltage?
