Hi,
Am after some advise on exhaust emissions for passing the MOT, have a VEMS install on an audi V8 and it runs sweet as nut, however I do not use catalitic convertors as the car its in is nearly 25yrs old, which means the tester used the old settings of max of 3,500 %vol CO, however the car was 5,697
Has anyone else had this problem, can a setting be changed to get it to lower the CO level,
Thanks any advise welcome p.s im no VEMS guru so please bare with it, many thanks regards danny
