Another issue; you are not defining the clip limit values for FMAPn in your code.

I have heard of Ford using a 'VRF' file for this but not an 'A2L'. I thought the latter was 3rd party produced.

I do not think the information came from a strategy document as they do not give parameter size, sign, address and scaling which was provided.

Thanks to Mike G I can confirm the scalar at 0xF234 is 'WOT Enrichment Threshold' (aka HWOTBP). It is probably an orphan left over from the strategy development.

That address does not appear to be used anywhere in the code. It is also at the start of the transmission related parameters so I suspect if it were used then it would be for something transmission related.

If you have a CBAZ* definition with THBP2 in it then the definition is wrong. If you post the address of the parameter I'll see what it actually is (assuming I have figured it out in my disassembly!).

THBP2 does not exist in the CBAZ* strategies.

Here are some values:

1 = Base idle rpm
2 = A/C rpm
3 = PAS rpm
4 = HEDF rpm
5 = Battery voltage rpm
6 = Extended idle rpm
7 = Transmission oil temperature rpm
8 = Heated windscreen rpm
9 = Transmission spin loss clip
10 = GPAS clip limited
20 = HICAM (FN825B (ACT))
21 = HICAM (FN825A (ECT))
22 = HICAM (FN826A (ECT at start))
23 = HICAM (FN826B (ACT at start))
24 = HICAM Buzz rpm
25 = Catch any hicam stack-up
30 = On Demand diagnostic test
31 = Fail safe cooling
99 = None of the above

You can find FN151 and FN152 in the strategy that the B9Z calibration uses.

I believe FN151 and FN152 are 'orphans' left over in the document from previous strategies that did not have FN1150.
