Totally stock. The reason I ask is because when I scanned with EFI-Live it said CL-fault for both banks when looking at the Fuel Status on the main Dashboard.

I left it at the default 14.7 - this is at idle.

Is there anywhere in the VCM Scanner that you can see if the engine is i closed loop?

What could be the cause for this?

Anytime i press "On" for AFR Control the engine dies immediately.

I have a standalone swap where the wires for the emissions components are removed from the harness.

The PCM now throws codes for:


Rear o2-sensors
AIR
EVAP

Thanks, should they switch more even at idle?

Here some additional log files. Both logs with the car stationary.

Does the O2-sensor signal in the logfile look ok for a cold start and then going in to closed loop?

Any comments on the log files?

Injectors are cleaned and flow tested.

Checked the plug leads yesterday and now I'm down to coils, pcm wiring harness or the pcm itself.

Is there any way to check if the coil is ok?

Thanks for all the feedback!

I have included two logs - do they look ok?

I just swapped my used LS1 long block with a new crate engine. The PCM will be re-used from the old engine. Both long blocks are stock engines. I am using the same PCM with the same tune.

Hi guys, I could really use your input on something.

If I put both hands on the intake manifold I can feel irregular skips/misses. The engine runs fine for a while and then a skip/miss. After this...

Do I need to do some kind of calibration of the PCM to adapt it to the new long block?

Will the ECU compensate for a lower fuel pressure than spec (58psi)?

What kind of symptoms would you notice with a slightly too low fuel pressure (46-50 psi)?
