Hello, Situation on Det3, Analog In #1 is connected to MAF.

MAF to Det3 Analog In #1  
Det3 Analog out to ECU

1. On software, Analog Signal Modification Step (V), which 1 to select?
2. How do I know which Analog Out Min (V) value is correct to key in the voltage?
3. How to set up the Analog Output Offset (V)?

Thank you

so you want to passthrough and modify the MAF signal going to stock ECU going through DET3 ?  
You should log first how the stock MAF behaves with the stock ECU and decide the max and min values first. Resolution i would choose max resolution step.  
Have you read the DET3 manual by any chance ?
