I strongly advise against using masterxresolve.com.
The software is advertised as a professional chiptuning solution, but in reality, it delivers dangerous and incorrect files.
In my case, a manual solution for a SID803A ECU resulted in a P0000 fault and limp mode. When I contacted support, they suggested an AdBlue reset... on a vehicle that doesn't even have an AdBlue system. This shows a complete lack of basic technical knowledge.
Furthermore, they refused to provide Stage 1 files that were explicitly included in my license, demanding an additional €4000 for a "higher" license. They refused a refund, and I only got my money back through a Stripe chargeback. Be careful – they are known for blocking users who criticize their low-quality, AI-generated files.
