Power enrichment here
Hi there,
Sorry I am late, but here is where it starts. Remember that at wide open throttle, you are under power enrichment, you will NEVER, nor should you ever be at 14.7 to 1 which is ideal.
Under power enrichment, you are adding extra fuel to prohibit detonation, this is a result of the calibration of the PCM.
Now, if you were experiencing other issues, like the detonation or whatever, you could have an issue, but on a dyno run, when you are at WOT, this should be considered normal.
I would consider you normal.
Just a side note, the 14 is the air side, and 1 is the fuel side, so you need 14.7 parts of air to 1 part fuel, correctly mixed, to create ideal combustion.
Best to you, so your spec of 13 parts to 1 part is actually rich, I will be on Thursday, so let me know what you have, c4c5
