I think with aux pump, the fscm isn't really pulling fuel pressure, it just lets the in tank pump to idle, because fpcm doesn't know where the fuel/pressure is coming from. When the aux pump can't provide enough fuel/pressure fpcm start to command more duty cycle from the in tank pump. That is semi slow process, as can be seen from your log, but I think it could be improved by tuning.
I'm just guessing,  |
Appreciate the thoughts. After doing some logging it turned out to be both ironically enough. By logging "calculated gear ratio" it indicated that the clutch is slipping as the ratio was changing mid pull. The aux pump was a tuning issue where the min fuel pump voltage table had to be adjusted.
Just glad it squared away. Time to save for a clutch
