There is no training available for the s58.. Hasn't even been officially described to us yet lol
The S55 impresses me more and more everyday.. It of course has an inherent Achilles heal like all M3 power plants that BMW NA refuses to admit is even an issue! It have been rod bearings for the s54 and s65.. Now with the S55 its crank hubs slipping and smashing the fuck outta half the valves! The timing chain sprocket on the crank isn't keyed.. Why would they do that kind of insanity that's worked for decades maybe centuries.. No they had to get all fancy and us a friction impregnated shim that well... DOES NOT WORK!! an over Rev.. High speed down shift even a K&N air filter get you a brand new head on your dime.. Fu king joke it is! They refuse to admit a design flaw and just keep passing the buck!
