My car is still running like total dog poo.

I have taken some logs with the TMO logger and they aren't good because the car spits and sputters a lot. TUNING LOGS


The car sometimes will be good in first and second, but then shakes like crazy and falls on its face. I'm assuming a tuning issue and or fuel, but I'm no expert especially when it comes to tuning.
If someone could just tell me whats wrong here and what the heck I'm looking at, I would appreciate it so much!



What I have done already; (some have no relevance to tuning)
Battery
Spark plugs (NGK BPR6ES)
Spark plug wires (NGK)
Coil
Fuel line between main and pump (in tank)




Thanks in advance!

what do you use to open those .tlg files? I tried searching online for software to open the file but couldn't find anything. I also tried searching for the TMO Logger software downloads and can't find anything

That car had ground issue out front also. I remember him telling me about un plugging something at times car would run better and reset itself. I chatted with him for awhile the previous owner.

Do you recall at all what the issue was exactly? What did he have to unplug?

Not if the top of my head. But i remember the grounds out front for battery relocation wasn’t the greatest setup on it. He had tons of software to go with it. If you had hard drive usb stick with you. He showed me it all. He used to rebuild Ecu’s back in the day for people.

If I do remember I’ll let you know for sure. I know the car has been sitting for long time

Could it be something to do with your 550cc injector 190lph pump? Definitely sounds like a tuning issue. Was the car running fine before and all of a sudden start driving bad?
Man I hope you get that figured out.

Can't read your logs, but I didn't see a fuel pressure regulator in your list. The factory one can't handle extra fuel. It will run rich in vacuum and might not raise 1:1 till your a few PSI in boost.
