In a recent thread, I mentioned that my fuel computer had the wrong program number.
This will not mean a lot to some people, but the general gist is that for the fuel computer to provide accurate figures, it needs to use certain values to make the calculations.
These values are:-
Engine Type (ECU type).
Road Wheel Size and tyre profile.
Miles or Kilometers.
Analogue or LCD instruments.
plus a few other bits n bobs that affect the overall fuel consumption data.
A fair few moons ago, I downloaded Ian Till's "Memories" Excel spread sheet.
I am not certain as to what state of dis-repair his old website is in - it was called ABS-Zero.
From memory, I understand that Ian is now highly placed in the VBOA, hosts of the annual July Auto-Jumble etc, now at Market Harborough, formerly the old Billing event.
I am re-presenting it here but with only the Cavalier memories..
And with a few minor corrections.
I did toy with the idea of listing Calibra too, as program No 130 is the most common.
Perhaps something for the future...
So here is the table in glorious techni-colour to make some options easier to spot.

The program numbers can be used to get your fuel computer set up correctly, if you ask your dealer or any acquaintances that you know may have an original "Tech 1" diagnostic / programming tool by Vetronix.
I would not be surprised if it is only independent vauxhall specialists now that have Tech 1, as I am sure Vauxhall dealers will not care to support older vehicles.
