So I unpacked and found the file and line you mention. Your values were as follows:
[AUTOBLIP]
ELECTRONIC=1
POINT_0=10 ; Time to reach full level
POINT_1=11 ; Time to start releasing gas
POINT_2=20 ; Time to reach 0 gas
LEVEL=0.4 ; Gas level to be reached
Wasn't sure about what to put, so just as a test to see if it affects something, I copied the values of a Kunos car, in this case the F138. Looks like this:
[AUTOBLIP]
ELECTRONIC=1
POINT_0=1 ; Time to reach full level
POINT_1=20 ; Time to start releasing gas
POINT_2=25 ; Time to reach 0 gas
LEVEL=1.0 ; Gas level to be reached
I then selected "Pack Data" in CM, in the corresponding car's tab. CM seemingly created a new data.acd successfully. But ultimately, it made no changes to the issue. I could've messed up the repacking bit, though. I assumed it packed the data folder it automatically generated previously.
Here is a clip of what's happening. I'm driving with the Xbox controller as I was just testing, but I ensured auto-lift and auto-blip were enabled in-game:

Let me know any info you need from me.
And huge thanks for bearing with me!
