The direction injection drive voltage varied between 2V to 80 and spikes up to 300 volts.
Every DI drive singal is slightly different from each other. Possibily the taken most part of our circuit design work, particularly on the input stage.

We have more or less summed up on most cars with the exception of the VW golf. We did not have any problem on their tdi (PID). Once we have established the pin 16 voltage, I will have a better understanding of the signal.

As regarding the FSI engine. Audi on partucular, the DI algorithm on the A3 fsi is again slightly different from the A4 fsi. This is most annoying for us. We are workign on the next generation of "all-in-one" detection circuit and should be ready soon. We are talking in week rather in months.

We shall see what more new surprises are installed for me when I get the pin16 voltage from you in the next few days.
