    RHDEngineering ITB

    My initial thought is that's a ton of money for 20 HP.

    i think 20hp is the bonus... the sound alone is probably going to be worth it!

    coding out the DISA will be a must, but it does mention about a "complete idle control valve circuit".... i mean, we've got DBW throttle bodies, so i wonder how they handle that.

    looks nice though. would love to hear how it sounds!

    EDIT: "Drive by wire throttle operation is not supported." whoops. i guess it's out of the question then...

    Yeah, this doesn't make sense. All M54's had drive-by-wire as far as I know... so how is this product supposed to be a bolt-on for a motor that utilized a drive-by-wire throttle body? lol

    It looks like you actually add a throttle cable during install...?

    This is a complete bolt on kit that will fit m54 bmw engines. Kit is supplied with standard m50/42/44 cable attachment that will fit both LH and RH drive vehicles. Drive by wire throttle operation is not supported.
    Edit: nvm. The engine pic below looks to be an S52. I don't know how this works.

    I have a feeling they are either falsely advertising this product or made an honest mistake stating it's for an M54. It's not as simple as "we've provided a throttle cable"... that requires modification to make it work, as well as the software (DME, MK60, maybe EWS?) implications of making this work in a non-halfass way (read: warning lights) makes this more complicated than they lead us to believe. That means this is not truly bolt-on for an M54 application...

    Interestingly enough I agree with your argument, but I follow @2MRichard if Iím not mistaken on IG and he has a Turbo Top Mount ZHP widebody coupe, and he has modified his throttle body to have a throttle cable, etc.... Not to say it is easy, but I agree with you on the heavy modification because his entire build appears to be custom, I question the integrity of this though because why has no one whether Race car or not, has had a true review of this product? i call false advertising

    There is probably only a handful of people in the country that would actually take an M54 this far...

    Yeah it says it comes with an M50/42/44 cable attachment so I'm guessing you have to install the cable and can no longer use drive by wire.

    I thought this looked pretty cool until I shit my pants at the price tag.
