While not deleted the Enviroment Variable ediabas_config_dir and using Node patched api32.dll in C:\EDIABAS\BIN ISTA very slow with ENET cable.
Tried replace C:\EDIABAS\BIN to 7.6 then INPA works very slow.
Deleted Enviroment Variable ediabas_config_dir and using Ediabas 7.3 with patched api32.dll both ISTA and INPA works normal

could you try to have ISTA+ in use on E-series....and then put it in backgroud and try to use NCS or INPA without closing connection in ISTa?

Hello, same as you I consider this a big minus for newest ISTA as it was very easier to work in previous version with Inpa or NcsExpert or Tool32 simultaneously while Ista was already opened and connected to car.
I've tried to replace the C:\EDIABAS\BIN with the one from Ista, I also replaced inside ista with another version of ediabas 7.6 but always when trying to open either one of the Inpa suite programs it will throw error with IFH 0018 and No api calls possible
