I know this is an old thread but just some clarifications on KFPED and KFPEDR wrt interpretation of the fields...
1. Cell fields are %, conversion constant is 327.68, values are UWORD (Unsigned Word entries in 16-bit resolution) 2. X-Axis fields are % PED, conversion constant is 655.35, values are UWORD (Unsigned Word entries in 16-bit resolution) 3. Y-Axis fields are U/min (rpm), conversion constant is 4.0, values are UWORD (Unsigned Word entries in 16-bit resolution)
For KFPED in the Alfa Romeo rom dump I found (for a 1600cc) X-Axis it was 16 Y-Axis it was 12
For KFPEDR (reversing) X-Axis it was 16 Y-Axis it was is 8
And both use the same conversion constants. Checked against several other rom's I had lying around and there isn't too much variation on this, at least on 512kbyte roms. Hope this is useful for anyon trying to make further understanding.
