QEICONbits.SWPAB = 0; // don't swap QEA and QEB inputs.


Change that to SWPAB = 1 instead?

i just removed the pull down resistors and now i have 4.16V max

i also tried to swap the inputs but the postcount is remaing the same

this is configuration code of an1162:

// ============= Encoder ===============

    MAXCNT = MotorParm.iCntsPerRev;    
    POSCNT = 0;
    QEICON = 0;
    QEICONbits.QEIM = 7;    // x4 reset by MAXCNT pulse
    QEICONbits.POSRES = 0;  // Don't allow Index pulse to reset counter
    QEICONbits.SWPAB = 1;   // direction 
    DFLTCON = 0;            // Digital filter set to off

i also tried to disable the filter but nothing changes..
