TPI '165 pulling timing after Cold start

[Dan Plaskett]

Hey Mark

I've got the ECMGuy's disassembly of the 165 here and this looks like a
knock test to me.  Am I wrong?

LC229:    FCB    235    ;  If KNOCK low time > 3.67 Sec, Enab ERR #43
                                     ;  CALIB = Arg * 64

LC22A:    FCB    45    ;  If ERR 43, then KNOCK retard 7.9 Deg
                                    ;  CALIB = Deg * 256/45

LC22B:    FCB    57    ;  Add 10 Deg Sprk Adv for #43 test
                                    ;  CALIB = Deg * 256/45

LC22C:    FCB    173  ;  90C (194) MIN COOL TO ENABLE ERR 43
                                    ;  CALIB = (Deg C + 40) * 256/192

LC22D:    FCB    170  ;  If LV < 170, Disable ERR 43

This is the 86 $32 calibration though.
