Can anybody tell me what the parameters mean in the Desiired flow vs. current table. I am trying to make adjustments for my modded fuel pump.
Thanks!

This table converts the desired fuel flow (mm3 per Second) to the amount of current required to obtain that flow.

what mods? assuming you opened up the FPRV to allow for more flow this should do it:

adjust the current up some in the lower mm3 areas and zero out the 52000 and 60000. smooth it out and test it. keep adjusting the top few tables (low mm3) until it actual Mpa matches the desired Mpa during idle.

when you get the idle Mpa worked out take it out for a drive and log the B1010 and actual vs desired Mpa. adjust the areas that don't match. higher current = lower pressure.

on mine i added about 20% to the entire B1010 table and almost nailed it, with a few tweaks to the idle area it was spot on and idled smoothly. depending on your mods it may take more or less changes to get it right.
