Whisper mode problems

[Power Hungry]

If you aren't sure, then yes... You'd probably have to pull the chip.

Are you running our canned tunes, or are they tunes from someone else? If they are our tunes, the filenames will begin with the calibration code and then the tune settings. For example:

VCAB0_02_100P = VCAB0_02 - 100 HP Performance
VCAB0_02_0WM = VCAB0_02 - 0 HP Whisper Mode

and so on.

I need the first part of the filename which is the calibration. Then I can go back and look at that specific tune and see if there's something I can address.

In general, the whisper mode tunes retard the timing about 8 degrees while dropping idle down to 525 RPM. If the engine is not fully warmed up, this can result in quite a bit of white smoke due to the retarded timing. I try to keep the smoke to a minimum, but engine condition and cylinder compression can make a big difference in just how much fuel gets through. Higher mileage engines exaggerate this problem and sometimes it's just not feasible to use this particular tune due to the amount of wear in the engine.

Also, the longer the engine idles at low RPM, the cooler the cylinders get. So the engine may not exhibit any having at first, but the longer you stay in low idle, the more haze you will develop.

Whisper Mode was never meant as a long-term means to quiet the idle. It's just to try to help quiet things down when going through a drive-thru or something like that.

I hope this is helpful.
