I went through Andre’s lecture regarding tip in enrichment and I have a question.

If my fuel trims are swinging between -25 and +25; based on when I let off the throttle or come on the throttle from cruise.

If I increase the IPW in the tip in table to correct the lean state and add more fuel…what will that do to the rich state where the ECU is taking out fuel to compensate for the rich state?

Will changing (increasing) the IPW on the tip in table affect/change BOTH the rich and lean fuel trim conditions?

I found a snapshot of my log that shows what I am talking about; i.e. tip in enrichment and enleanment when on and off the throttle; even slightly.

How can I fix this issue?
