;:Bits:

bit Short Note
060h MAP CEL bit set if map too high!!
017h   sign of difference between newest and oldest RPM value (1 is negative)
02Eh   set when below RPM limit
057.0 IGN fire Firing number!!!
057.1 IGN fire Firing number!!!
071.1 rpm > 3E,46 (~890,950rpm) target idle??
071.2 rpm > E2,E5 (~5400,5600rpm)
071.3 map > 9C,A3 (~9.3,8.7 in Hg)
071.4 map > B9,BC (~6.0,5.0 in Hg)
079.4 rpm > B7,BE (~3400,3650rpm) -> 038h is used for MAP value if set
079.6 map > B9,C0 (~6.0,4.0 in Hg)
07A.4 map > AE,B9 (~8.1,6.0 in Hg)

;:XRAM (MOVX 1XXX) (5128 XRAM chip)

Addr Short Notes

032.2 rpm > 06,14 (540,630rpm)
032.3 map > CB,CF (~2.5,1.0 in Hg)
07Dh ADC address stored in this is where 4001 from MOVX is put (ADC)
0A1h   current checksum value
0A2h   next DPH value for checksum
