MEFI4B with TunerPro RT

Post by michael55123 »

Is it possible to use TuberPro Rt with Mefi 4B? I have paid for MefiBurn but it seems the definition files are not actually correct for Tuner Pro RT?
Thanks,
Mike

Hi Mike, it's possible to use TunerPro RT with MEFI 4B, but you need the correct .xdf (definition) files specifically tailored for the MEFI 4B ECU. The files provided with MefiBurn are primarily for flashing and diagnostics, not detailed tuning like in TunerPro. You’ll need to either source a compatible MEFI 4B .xdf file from the tuning community or create one based on the ECU’s bin structure — otherwise, TunerPro won’t interpret the data correctly.
