For anyone that likes playing around with this stuff:
I've always thought the PE vs. TPS table was somewhat useless. Once your in PE, you're half way throught the table in a lot of instances. I know you can use it to alter part throttle fuel and such, but some cars make a lot of boost at part throttle, others don't. What if the table referenced airflow, so it knew how much boost (kind of, actually airflow) there was?
I've been playing around with PE vs. Airflow instead. By changing address $3BBB from $36 (TPS) to $7E (Airflow), the PE vs. TPS table will no longer reference TPS, it will reference Airflow. So now the table is called PE vs. Airflow.
Instead of the 9 value table being:
TPS%
0
13
25
38
50
63
75
88
100
It will be:
Gr/sec
0
32
64
96
128
160
192
224
255
It seems to work fairly well so far.
Just something to play with....
