It seems that this 16 bit ROM is a bit :wink: short on tables that are vital when upgrading to larger injectors. If someone has addresses and definitions for these tables or could dig them out of this ROM it would be a huge help. I'm sure there are some I'm not aware of. Feel free to add those as well. Here are a few that would be valuable if they are available for this rom:

  1. Fuel Pump Duty Switch Points:
    • Fuel Pump Duty High (Injector Duty Cycle)
    • Fuel Pump Duty Medium (Injector Duty Cycle)
  2. Atmospheric pressure sensor scaling
  3. Fuel Pump Duty
    • Fuel Pump Duty (Idle)
    • Fuel Pump Duty (Cruise)
  4. Tip-in and tip-out ignition timing:
    (whatever controls the major ignition timing changes on and off throttle)
    • Ignition Timing Comp Overrun RPM Delta?
    • Table Ignition Timing Comp Overrun?
  5. Deceleration/Overrun fueling:
    • Fuel Resume Initial Pulse RPM Delta Threshold
    • Fuel Resume Initial Injector Pulsewidth
    • Overrun Fueling RPM Resume Threshold
    • Fuel Cut Base Delay 4x4 table
    • Neutral Delay
    • Sequential Delay Additive
    • Sequential Delay Additive RPM Threshold
  6. Low Injector Pulse Width tables:
    • Minimum Injector Pulsewidth

Thanks to Td-d, jon7009, limequat, and The Lorax, the tables in gray are already defined! Thanks

There are still a few tables left to define but here are the improved definitions for A4TF800F using EcuFlash.
