ECM Tune Resistor 3.9 V8 Disco 1 1998

Does any one have experience swapping the Tune Resistor for a different value. 
In the manual it shows different values for non cat of 470 ohms for UK and 180 ohms non cat Aussie.
This must change the mapping but in what way?
Ive fitted tubular headers and am looking at ways to ensure fuelling is correct without the expense of a $1000 chip if its req.
