    Z4M specific bells for AP Racing Pro5000R BTCC Kit - interest?

    Exactly this, with a thicker disk it gets too close to our e36 style steering knuckle and the splash guard than is ideal. Hence AP making a specific kit that reduces the offset of the mounting bell and adjusts the bracket to reposition the disc and caliper further out into the wheel

    BMW Z4M S54 - slight hesitation/stutter when you press the accelerator from idle.

    Interesting. It's a real head scratcher. I have no idea how mine was fixed in that case. Odd

    BMW Z4M S54 - slight hesitation/stutter when you press the accelerator from idle.

    Not wanting to open that can of worms again:popcorn:but was the map done by evolve/eventuri/imran whoever you want to call them?:) When I had their map on my m3 wide open throttle inputs (if I remember right) in 3rd gear would cause the engine to bog/stutter, I'm not quite sure how to describe...

    BMW Z4M S54 - slight hesitation/stutter when you press the accelerator from idle.

    That's what I would like to know! But even if everyone who has one chimes in to say they don't have this problem the sample set would be small enough that drawing any real conclusions would be a folly. There's what, 5-10 of us on here with one, I don't think more.

    BMW Z4M S54 - slight hesitation/stutter when you press the accelerator from idle.

    I didn't think testing knock sensors for resistance is really a thing? Resistance changes cannot tell you if the sensor is actually generating a voltage when the engine knocks. Pelican suggests testing s54 knock sensors with a volt meter at the dme pin outs... "Testing knock sensors: To test the...

    FOR SALE BMW Z4 M Brake Cooling Kit

    I might jump in too. Need to chat to Andre to see what can be kept from my original kit, prob not much. Perhaps unsurprisingly the front ducts have taken a bit of a hammering so I ought to get those too. Looks like the latest iterations are a lot stonger🤞

    Preventative maintenance

    I always have a spare tps with me, not that it will hault complete progress but its no fun to drive with a failed one and they're easy change, particularly the top one. Pre cat 02 sensors and cam and crank position sensors might be worth having in the boot, but you'd need a few tools along with...

    BMW Z4M S54 - slight hesitation/stutter when you press the accelerator from idle.

    I reckon it would be interesting to disconnect the MAF from a car with the problem. It will then run on a basic 'apha-n' map, something similar to those of us with a csl box and associated map. The car won't run amazingly I'd imagine but would be interesting to see if the rev drop issue...

    BMW Z4M S54 - slight hesitation/stutter when you press the accelerator from idle.

    Andy, you'd be more than welcome to use my spare actuator for testing, just let me know. Like you though I dont think its the issue, it is of course the exact same part as the e46m3 where this problem does not manifest itself at all. When I bought my car in 2013 it had this issue, I remember...

    Z4M Oil Cooling Solutions?

    Presumably that's for water temps as there is no oil temp warning light, only for pressure and level. 143 is high but it's within tolerance, the manual states not to exceed 150c and the castrol 10w60 is also good for that, however it will probably shear down to at least a 40 pretty quickly, so...

    Thruxton Howl

    A grand for thruxton is a bit rich for me, but I'm sure it will be fun! Be good to see them doing the podcast too, enjoy. I went there on a similar day with the intercooler a few years ago, there was some interesting stuff there, not least the old formula 1 cars sky were filming during the lunch...

    SOLD Z4M Front calipers / Carriers / Brake pads

    I'm not sure if it's still a thing but the carriers were worth good money to the e46m3 crowd to upgrade to csl spec (calipers are the same between the two of course). Put an ad up on cutters perhaps? I seem to remember selling mine for 150 or so but it was a long time ago so that might be way out.
