    It'll pass the plug in but no visual or sniffer obviously

    With Renovelo Bytetuner out, I dont know if I see any reason to convert to MS43 anymore. You can tune MS45.1 and someone just figured out how to force the cats to show readiness too (published on ms4x.net).

    I suppose if you need to go really exotic with your build like super high boost with a super aggressive turbo or supercharger setup (think ESS TS stage 3 with lower compression pistons, or E85, etc) then swapping to MS43 still makes sense IMO.

    Yeah like mine. Ethanol, boost, maf flexibility, well defined tables and tuners that know it. Ms45 won't ever be what ms43 is
