    LC-2 is connected with serial connection to V2

    LS1_Link
    ;Main VE Table
    B0101.ROW=SAE.RPM
    B0101.COL=SAE.MAP
    B0101.RRR=CALC.BEN1


    Have contact between V7 and RoadRunner, but do not get the same values in the V7Scan Vet Map as in RoadRunner B0101 , and the values in RTACS increases quickly to max limit .

    Has taken out the LC-2 wideband sensor and calibrate it, has also installed an additional Autometer wideband lambda to compare the values and test again. (have to wait for some nice weather outside).

    LC-2 in bank 1 and Autometer widband i bank 2
