I had been using ISTA+ with my F10 for years, and before that I was using DIS and SSS on my E53. Long story short, the F10 is no more (totaled), I no longer have DIS/SSS/INPA/Progman, and now I'm visiting dealer auctions looking at E-chassis cars that won't communicate over the F-chassis' ENET interface. I still have my USB-->OBD2 dongle and (for some reason) an older serial-->OBD2 dongle.

So, ISTA works with the E-chassis? Does anyone have any tips? I never was able to get my USB->OBD2 dongle working with ISTA.

Yes, it works very well. I'm in the process of writing a how to on what I'm up to with ISTA and my e53 4.8is

Cheers

Awesome! Keep me posted!
