Your fuel multiplier works in the fuel pressure.. You can change the fuel pressue in the map under, paramaters, fuel trim, then "calc". Then just manually adjust the fuel pressure accordingly.

in normal operation the A/C(B5) input is expecting to be pulled from high to low when activated.
ie,when u apply a ground connection(low) to pin B5(which is normally high when no connection to pin B5),then ECU thinks A/C activated,or in your case "activate datalog"

so,yes,wire B5 input to one ...

So i dunno if im blind? I cant seem to find anywhere that explains how to hook up the switch for dataloging?

Im using pin B5 (AC switch) for actiavation. Do i have to apply power or Ground to this terminal to turn on the datalogging?

Thank you, i knew i had seen a chart like that b4 but i couldnt for the life of me find it??
