Does Softechpro Solutions disable P2112 cleanly without breaking other diagnostics?
Yes. Softechpro Solutions v2.0.6 parses the exact manufacturer fault-code and switch tables inside your 100% virgin binary so only P2112 / Swirl Flaps / TVA / Lambda / DTC Off is deactivated while all other engine protections remain active.
