Stock FPR - 38psi.

I thought your fuel pressure should be set at 43.5 psi. Someone please correct me if im wrong. This could be a big issue with your idle.

1g manual vehicles have 38 psi as base. The OP needs to take this into account for his global fuel % (which is currently off). Use the build in calculator and adjust the necessary values.

Do you have an ISC? If so, it may be bad (seeing ISCPosition at 0).
Your front o2 seems to be not reading correctly - are you sure that it is in good condition?
Have you done a boost leak test recently?

Is that not an aeromotive fpr on your firewall?

That is a sweet ride to man! Good luck.

For this log I used N/T fpr.I will return 1G turbo fpr to see what happens.
Also I don't know why ISC read 0. I Test it works

I tried to adjust to global fuel correctly to FIC 1150cc Global - 61 and Deadtime - 330 but the engine off and getting worse.
I Test ISC it works cold read 80 hot falls to 0
I use Zeitronix Zt-2 Wideband A/F Ratio Meter with Dsmlink v3
From Zeitronix Wire purple simulated Narrowband 02 Output directly to pin 4 ECU 02 oxygen sensor and Zeitronix Wire white Wideband analog Output directly to pin 15 ECU EGR.
I think this is correct.

Is that not an aeromotive fpr on your firewall?

Yes it's Aeromotive fpr not yet installed.
I just want to drive the car correctly with dsmlink SD to go forward with tuning.

New log with 1G turbo fpr 38psi.
