You read codes via the JB4.

Sure but if it's not coming up on map0 it won't be a hardware issue. Likely a software issue, so the data cable or blue tooth will let you read the code, adjust settings, do logs, etc, so we can resolve it.

Tnx for all your help , new s/w is uploaded and seems to work well . about the check engine i notice when it come up it only when starting the car and never during drive (bot hard and soft drive ) it doesn't happen always but when it does it when i start the car.
i notice that my value of TMAP 3.5bar=1 , 4 bar =2 is set to 1 , is it right or should be 0? is there a way to turn on and off the Fuel gage boost from the interface or on from the car itself? . i can share the CSV file but again the check engine is not coming on during that drive test, LMK and again many tnx!
