Martyn's Z4M Coupe
One of the best threads in ages this, hats off to you Martyn! So refreshing to see someone rolling their sleeves up and fettling an M instead of banging on about future values and maintaining main dealer service history...!

Thanks!
The Maxx is awesome, I remade my plug and play adapter so I could tuck everything neatly away by the GM5 module.
I also added the provision for plugging in the DCT loom, shifter and drive logic button in case I decide to DCT the car at a later date
After re-making the loom I fired it up and checked everything still worked

I've hooked up one of the additional air temp sensors so I can have pre and post charge cooler temps, and I've also hooked up the PWM line to one of the Maxx's outputs so I can control the pump speed via PWM.
I was all ready to start dialling the car in on the Maxx but I noticed the BSD functions werent working meaning no oil temp or alternator control, thankfully MaxxECU have shipped me a new BSD module to try as I'm confident in my wiring.
Other than that I've barely driven the car to be honest.

Thanks
I got my replacement BSD board wired in and started tuning the Maxx for the SC setup. Also got my old Nvidia tablet setup with MDash, which is a dash app from MaxxECU.
MDash is excellent, you can pick any of the hundreds of parameters to display and it's streamed realtime over bluetooth.

What a great idea. One of my exhaust flanges has disintegrated so I'll be doing this. Thanks for sharing.Martyn wrote: ↑Tue Nov 29, 2022 11:38 amTIS doesn't mention anything about preloading the CSB on the Z4M interestingly enough. I know the preloading was required on older BMWs though.grannyknot wrote: ↑Sun Nov 27, 2022 10:17 pm Great work Martyn, just a note before you install the heat baffles, that centre bearing on the driveshaft has to be pre-tensioned toward the rear of the car. You'll notice the slots on the mounts of the bearing, it's not a lot but it is suppose to help.
I had an hour or so on the car yesterday so my attention turned to yet more exhaust work. Upon removing the center section I noticed some cracking on the flanges of both the back boxes and the center section.
I bust out the tig and managed to weld the crack up on the center section, but this wasn't going to work on the back boxes due to how thin the metal was and how close to the edge the crack ran. I'm convinced the aftermarket 2 pieces exhaust clamps are the cause of these cracks.
I pulled off the back boxes and noticed that one of the hangers had cracked at the weld, so I cleaned that up and tig'd it (didn't get a picture as it wasn't particularly pretty, however it'll hold fine).
Next I cut off all 4 flanges Back box flanges shown below.
Test fit of a 2.25" / 58mm sleeve clamp.
Like a glove!
I popped the center section and back boxes back on to the car and called it day
My "brand new" second hand headers turned up this morning so I hope to get those wrapped today and fitted.

My Ultra Racing brace finally turned up so I chucked that on at lunch time today.
It's certainly a tight fit around the IACV hose.

I remember looking this up in TIS too as I was expecting it to be preloaded like in the E46 M3 I did a few years back but no mention of it for the Z4M. From what I understand, the Z4M propshaft doesn't have a separate ACB bearing on the front half of the propshaft so doesn't require preloading.Martyn wrote: ↑Tue Nov 29, 2022 11:38 amTIS doesn't mention anything about preloading the CSB on the Z4M interestingly enough.

Hey,
No real updates as such, although I do have a few things on my list I need to sort:
- Replace supercharger belt, along with the top idler pulley.
- Replace the alternator which is throwing BSD errors.
- Fix a slow leak with the washer bottle / headlight washers.
Replacing the alternator will be a pain as the bottom alternator bolt (supplied with the SC kit) is too long to remove without tilting the engine or removing the front end of the car
