Throttle Enrichment Trigger

[UNISA JECS]

Hey Matt I believe the Throttle Enrichment Trigger follows the LOAD/TP AKA "Value" scale can you fix this? Its very clear to see during a log that the current scale for the Throttle Enrichment Trigger makes no sense at all.

But I do believe I know what this scale does do, and is very helpful to eliminate very light throttle transitions especially on a boosted engine were is this is not scaled down AKA turned off you will get lean AFR under light throttle boost situations.

It appears that only half the scale is being used because max TPS voltage (regaurdless of RPM) will only move the cursor to block 8 (middle of map) (2800rpm - 96mv).

Looked into this. The definintions for the B14 dont match the earlier models. Those first two tables are actually as below. Yes you are correct in that the RPM scales are 0..3200 (checked against h/w maptrace on the bench today)

Address definition should be updated to:

#Throttle enrichment
#1. Fast movement vs temp and RPM are multiplied together
THROTTLE_ENRICH_FAST_MOVE_TEMP,&HF1C0,16,1,16,1,Throttle enrich vs Temp
THROTTLE_ENRICH_FAST_MOVE_RPM,&HE390,16,1,16,1,Throttle enrich vs RPM
#2. Additional offset added to TPS voltage
THROTTLE_OPEN_OFFSET,&H0000,0,0,0,0
#3. Determining table switching from TPS enrich to fuel maps
Q_OFFSET_RPM,&H0000,0,0,0,0
#4. Amount of TPS voltage before using fuel maps
TPS_ENRICHMENT_TRIGGER,&H0000,0,0,0,0

I'm unsure of the last three for the B14 but the first two which you are using determine temperature and RPM used for throttle response
