Hi,
Read this. Someone's there with a 78SC as well.
Anyone use a Gunson Gastester on a Motronic car?
The LM-1 was DEVELOPED on an 80SC engine to set (and control) CIS mixtures. It's not exclusively a Motronic Tool. Actually about 50% of users use it for Carb tuning. Some even use it for diesels.
Regards,
