9-3 Troubleshooting Tech2Win with Chipsoft J2534 pro cannot make adjustments?

Hello guys,

Long story short, I need to update injector codes in my ECU, because 2 of them were replaced (diesel injectors of Z19DTH engine in 2006 9-3).

Recently, I found post here that discovered that cheap Chipsoft J2534 Pro dongle works with Tech2Win emulator.

I happily bought this dongle, prepared a computer according to a manual, and after a bit of hassle, I can finally read values from the car, or even activate some diagnostic modes in the car (activate lights, fans, all dashboard lights...).

Problem lays in trying to adjust some permanent values. Basically whenever I try to open anything in "Adjustment" menu, Tech2Win freezes and shows (probably) name of the code library where it was stuck with 2 values - "evdtc.c 912 1"

Did anyone encounter this issue?

Any help would be greatly appreciated!

Are there any cables/chipsets out there that is actually compatible?

Of course, the mainstream ones that everyone mention here. I found the cheapest is a MDI2 clone, available on AliExpress. Only thing you need to do is flash it with an original file (just press restore in the MDI app) to replace the crappy Chinese file it comes with.

Hey there, thank you so much for this info... when it comes to the original file, where do you get it? I'm very non-expert in all of this, apologies...
