Hi,
I 've checked like you said,everything works great
!!
I first try with 47k pot reducing slowly to zero Ohm and when the adc gauge gave me "0 volt" Vemstune switched to the table "B".
For information I've used the EC18 pin6 input and grounded-it with the "common sensor ground" with a normally open contact from a relay activated by the LPG electro valve.
Now I'm able to run different VE-Table and lower the boost pressure when running in LPG mode fuel.
I can also decrease the warm-up-enr in lpg fuel,etc ...etc...
Nice job and thanks for your help!!!
Regards,Michele.
