Type 4 B14 SR20DE additional tables

[UNISA JECS]

Hey Matt any chance you can look into these tables I found using a S14 KA24DE ADR for the B14 SR20DE ECU, thank you sir.

P.S. I recall a long time ago "enrich cold crank" used to exist and it worked

Feature pack removed some of the maps

Enrich (Cold crank/Warm crank) were combined into Enrich (Warm Crank) in Feature Pack. So just a single enrichment table regardless if the temperature was above/below 15degC at time of cranking

Added:

#New tables to be tested
FUEL_MAP_ENRICH_TABLE_OFFSET,&HE063,2,1,2,1
FUEL_MAP_ENRICH_TABLE_RPM,&HE210,16,1,16,1

FUEL_TPS_ADJUST_COUNTER1,&HE05A,1,1,1,1
FUEL_TPS_ADJUST_COUNTER2,&HE05B,1,1,1,1

FUEL_TPS_LIMP_VE_LOAD_BASE,&HE098,1,1,1,1
FUEL_TPS_LIMP_VE_LOAD_MULTIPLIER,&HE087,1,1,1,1

S14/B14 share the same addresses, however many of these are guesses from disassembly so only available in the 'expert' or development view

The last two are when the TPS is not used for VE map tracing, and as a backup load is used instead. See last two lines. So normally those would not be used

I've attached an address file update to put in your address file folder (used by 97 B14 also)
