Wastegate maps SIMOS 18 2.0 TSI

Hello all,

Could anyone tell me how the boost pressure actuator maps (wastegate) works within SIMOS18 for 2.0 TSI engines?

What do you need exactly?

32768 value in 16 bit means the wastegate is at 0.00, completely open, 49152 means closed, factor is (eeprom*0.000061035156)-2

Hi,

I don't think you know about what maps in SIMOS18 I am talking. Within SIMOS18 the wastegate position is not calibrated one o one. Only with factors. This map is called "Map for boost pressure actuator setpoint"

i do know what maps you're talking about, i modify them in all of my files from stage 1 to big turbo files and in simos 10/12/18, like i said the map works with a factor from 0 to 1 (0.2xx,0.5xx, 0.8xx, etc), 0.000 means the wastegate is completely open, 1 means its completely closed and will build boost as fast as it can, you can tune them quite a bit and will need to do so with a big turbo like a tte525, gtx30, and more, if you need help with this ecu, pm me ill help out
