What parameters activates PE?

[Saltsjoqvarn]

Hi

When I scan my car (LQ9 with LS1B PCM) the commanded AFR is 14.63 all the time (except for two short spots). What parameters activates PE?
My car running lean at load. Should B4206 be enable or disable?

Am I missing something?

Replying from my phone, make sure the PE Delay timer is set to 0. I forget what the LQ9 had stock, but the LQ4 had a 60 second timer.

It is set to 0 sec but it does not activate.

check if your b3616 is not set too conservatively. or just step on it.

Your datalog shows to be doing what the tune is telling it to do. It goes into PE at frames 2197 and 5352 because the settings in B3616 were met.

If you want to bring PE in sooner just lower B3616
