I have changed the tpsdot acceleration settings, but the megasquirt seems not to accept the changes. It seems to only use the original default settings. Am I doing something wrong? Please look at my tune and the Log file and help me reduce the "pumpshot"

What values won't change? I went into your tune and had no problems making changes. Your accel time is less than the taper time, just set the taper time to zero for now. Your accel time is also quite short, your log file did show overfueling but at one spot it did swing back the other way because of the short time. I'd lessen the added fuel and increase the time to 0.7-0.8 seconds.

when you changed the settings, did you remember to burn them to the ecu, I cant remember if accel enrichment requires a power cycle, but either way when you make the changes and load them into the ecu. just power cycle the ecu...and all will be fine with the world.
