3.5 years ago (!) when I first bought the VEMS 3.3, I had some project for my Volvo 850.
Since then I had a Maserati biturbo and so I was more involved during my spare time with mechanics than with electronics or software. Hopefully the car is 200km from where I live !
This biturbo has an odd fire engine with bizarre triggers so that the distributorless biturbos produced at the end were more easily equiped by Maserati with 2 ECUS, each one dealing with an 1/2 engine which is then 3 cylinders even fire.
Recently I aimed to use Vems to measure C0% at idle in order to fine tune the A/F potentiometer set on the Weber injection ECU.
My first issue is that I did not get the good O2 percentage for the free air test !
