  3. Install ESysLauncherPremiumSetup_2.4.3 , (Requires MS .NET Framework 4.0). Again, just click through, use default location etc.

What’s the difference between E-Sys software and Rheingold software? Which should I use if/when I get the dealer to update my car’s software and lose all of the tweaks I’ve made?

Esys = coding
Rheingold = dealer diagnosis system (ISTA)

ISTA+ can do VO coding.


  • Interface = K+DCAN Cable or ICOM
  • ECU Data Files = SP-Daten
  • NCS Expert = Coding Software
  • WinKFP = Programming (Flashing) Software
  • EDIABAS = Low Level ECU Communication Software used by NCS Expert & WinKFP

Fxx- / Ixx- / Gxx-Series, Mini & Rolls-Royce:

  • Interface = ENET Cable or ICOM
  • ECU Data Files = PSdZData
  • E-Sys = Coding Software
  • E-Sys = Programming (Flashing) Software


  • ICOM A/A2/A3/ICOM NEXT: main interface
  • ICOM B: adapter for programming multimedia in E series
  • ICOM C: adapter for old BMW with round 20 pin diagnostic plug
  • ICOM D: adapter for motorcycles

Additional Dealership Level Software

  • ISTA+ (AKA Rheingold or ISTA-D)
    • DIAGNOSTICS for All Vehicles
    • PROGRAMMING for F/I/G/RR & MINI, but requires ICOM
  • ISTA-P
    • PROGRAMMING traditionally for all chassis, but is being phased out by August 2017, except for legacy E-series.
    • ICOM Recommended. An ICOM emulator with K+DCAN or ENET can be used, but will NOT not communicate over all protocols to program every ECU.
  • Replacement ECU’s must be NEW
