Scant info to be found from the quick search i did, but assuming you have lbl files for another engine of same era then would just compare to what vcds presents with no label file.
I found this info and it seems like the label file would be rather easy compared to the d3 twin ecu file i had to make.
Have a look at the following link to see if it matches up with what yo have
