I keep having insane lean, then insane rich spikes in my truck. It happens open or closed loop, speed density or MAF tuned. It always happens under heavy load, but not full throttle. It really shows up when the torque converter locks up at 46mph.
It happens same load, same MAP KPA, same MAF HZ, same everything as other hits....in the hundreds....that were fine.
This is a custom everything engine. Vortec 350, custom intake, custom fuel system with LS3 injectors, fuel pressure is 58psi, all ran by an 0411 computer in my S10. Since we do not have a "bastard child" forum, I think it fits best here since it uses an 0411 setup.
Attached is my tune and log files. Also included my scanner config file if you want to see what i am logging.
The frames you want to look at is:
1611-1773
2475-2571
11090-11223
Please, for the love of god, help me out here. Before I set it on fire.
