First time I tried to generate an xhorse vvdi super chip as a PCF7935 but it didn’t work with the Alfa Romeo 166. Then i genearte the xt27 as ID44 Volkswagen. That’s how it worked.
1. Generate super chip as ID44 Volkswagen
Insert super chip into vvdi key tool max
identify chip type PCF7936
Go to Generate transponder function
Generate as ID44 Volkswagen

2. Write key with VVDI2
