Can you, all you are, add what you know (only if you are sure) in this excel table ?
put here after each mods.

Here you all go.

This spreadsheet covers:

rpm related : ALL OBDI
Ignition & Fuel maps + conversions : OBDI 305_P30.

Additionally:
this spreadsheets fuel & ignition conversion works for all other P30 ECU's
but the memory locations are different.

For the P30_203:

Low Speed Fuel Map: (20x10)
7032->70F9
High Speed Fuel Map: (20x10)
7104->71CB
Additional Fuel Lookup Map : (11x10)
71D6->7234

Low Speed Ignition Map: (20x10)
724E->7315
High Speed Ignition Map: (20x10)
7316->73DD
Additional Timing Lookup Map : (11x10)
73DE->744B

Enjoy

Here's a primer for the OBD0 non-VTEC ECUs in the ROM library.

I would have added to Nico's Bible, but most of the table identifications are very rudimentary and an .xls worksheet is restrictive, IMO. As an ECU becomes more developed, fleshing out the Bible is called for.
