HOW COULD I SAFELY INCREASE TIME WITHOUT KNOCK SENSOR? I HAVE DATALOG AND BIN

Where in the datalog are you talking about having an RPM issue? It's almost 12 minutes long, and I couldn't quickly identify the area of your concern.

In my opinion, you need to put the car on a dyno to see the effects on horsepower output when you adjust timing. This is the only safe way.

If you look at the log you can see that in WOT about 6500 to 7200 during the time in which the rpm rises, it works as follows (example): 6500, 6525... 6400... 6550....6600...etc

hello please need help

I zoomed in around the 2:00 minute mark - is that where you're talking about? The RPM graph isn't buttery smooth, but are you feeling this in the car or are you just concerned that it isn't a smooth line? What is the real issue you are having?

[jonatan riaño]

I wanted to know if it is really normal since the car runs fine

I wouldn't worry about it until it becomes an issue or until the noise gets very large. It's probably just noise in the signal.
