I have a peculiar problem that I have been working on with Gary at Perfect Pass. Just curious if anyone else has had the same problem and you have been able to fix it.
I have an 07 MB Sports B52V with the PCM Excalibur 330 hp engine. According to Gary, this engine is electronically controlled (fly by wire) with their "Digital Pro" module. This means the PP module talks directly to the engine computer for throttle control.
When PP engages in cuts the throttle back significantly to where it has to come in with full throttle to reengage. For wakeboarding speeds it will eventually home in depending on how much ballast. When surfing, it hits 11mph and cuts the throttle which drops speed to 7mph and starts an endless chase for the setpoint. We advanced the CR/CS value to fine tune the engagement but increasing the value only helped a little if any until 1700 setting. Beyond that there was no change in the engagement behavior.
Note: I upgraded to the Stargazer GPS but this did not improve the throttle cutting back. Please help is you have any ideas. Thanks in advance!
