Work's been stupid, but I finally got out to the garage today.

Pretty happy with this.



Next: rad supports, lower braces for this new core support structure, extending it down to tie in lower in the frame and act as the main mounting structure for the splitter.

PM me, happy to have guests through the shop.

For a collection of reasons it's pretty important to me that the car is running and driving in January. So... maybe I can make that happen this time.

Because it's important that the car is running and driving in January, the AEM Infinity 708 and Aeromotive fuel system just showed up.

Wait.

Shit.

We don't, really. I combined the BimmerWorld E46 M3 and E46 32x hose kits (because, my logic: our cars need the M3's engine-side fittings but the 32x-side rad-side fittings since we use a 32x radiator on an S54) to make a set that works for my application, but bear in mind that I've cut up the rad support on my car so YMMV here.

So the Infinity 708, mini harness, fuel pump / filter / regulator, and a shitload of switches, relays, wire, connectors, etc. have arrived. This weekend I start re-wiring the car from scratch, basically.

I have everything mapped out except the VANOS control and drive-by-wire pedal input. I know the Infinity supports both, just need to chat with AEM about the canonical way to do so. And also hopefully talk them into sending me the base start map for the E46 M3 plug-and-play unit, because god damn would that ever save me a bunch of time.

edit: current draft of the wiring:

Indeed, thanks though!

news is the E46 plug-and-play harness has H-bridge drivers for both VANOS and coil drivers hidden in it, so the Infinity isn't actually out-of-the-box compatible with the S54 and now I need to talk to AEM to see if they'll sell me the driver schematic or something rather than a plug-and-play harness that I'll need to completely butcher to make work.

Dammit.

That's kind of you to say.

So hey, I now actually understand how the S54 VANOS control is different than other VANOS / variable cam timing, and more importantly, I understand why. I've never seen this written in one place before so I'm just writing it here in case it helps other folks understand in the future.

Each cam has a separate advance / retard solenoid, and that was bending my head for a long time, especially after I saw that AEM drives that pair of solenoids using exactly inverted maps (i.e. if "advance" is at 80%, "retard" is always at 20%, and vice versa). I've read every bit of technical and training literature BMW made available for the S54 and I still couldn't really grok why that was important until today I read this in the WDS:

"When the relevant optimum camshaft position is reached, the solenoid valves maintain a constant oil volume in the adjustment cylinder on both sides of the chamber so that the camshafts remain in the corresponding positions."

Oh, for crying out loud. The VANOS solenoids control pintle valves between the high-pressure side of things (including the accumulator) on either side of a diaphragm, and it is the difference in pressure between the two sides of the diaphragm that dictates its position and therefore how far the splined shafts push into the cams and therefore how advanced / retarded the cam timing is.

Lots of interesting implications of this, but the most / least interesting implication is that I don't have to do anything even remotely fancy to drive it using the Infinity - just need to convert low-side (ground-switch) to high-side (+12V-switch) PWM with some reasonable amount of current-handling capacity and the rest is straightforward.

Solved the ignition coil situation by ordering a pair of AEM 30-2843 3-channel coil driver modules. Should make things nice and neat.

Finally, I have the whole ECM wiring harness (well, all of it that I care about) for the Z4M mapped out with wire colours and signal names and am integrating that with my previous draft wiring diagram. Should be able to sort out VANOS coil drivers tonight / tomorrow and then actually start building this new harness.

Again, awfully kind. I'm just an OCD / ADHD nerd, really.

That being said, this is a nearly-complete wiring diagram for using an Infinity 7xx with the Z4M (including the connector ID, pin, and wire colour for each connection on the stock ECM harnesS). I haven't mapped out any of the CAN stuff and have left out things like the the MAF since I'm not running one, and I need to experiment a bit with the H-bridge motor drivers I've ordered to see how best to wire that subsystem, but based on what I've learned / figured out I'm no longer worried about it.

Power / sensor harness:


Coil / injector harness:


DBW / VANOS harness:


Chassis blocks that I'll figure out as I go:


AEM coil drivers showed up today, too, so I think I'm actually ready to start.

edit: fixed a small issue with the VANOS/DBW diagram

If you get the standalone working properly that's going to be a HUGE contribution to tuning these cars in the future. So many companies have "said" they've done it (HPF single turbo kits, custom turbo kit Z4MR thread, and some N/A builds) but no one has posted videos or even pictures of it working, or even cared to explain how they got it working. Are you keeping the stock DME in place for controls over the interior stuff? Or going full AEM to control everything for the car?

I'm ripping everything out, it'll be a stripped interior with everything powered through the harness I'm building. I may keep one or two of the chassis computers (i.e. the one that controls power windows and doors) but we'll see.

A shop in France (comics69 on this board, in this thread) had video up (since removed, apparently) of their Z4M racecar running the E46 M3 PNP version of the Infinity 7xx including the stock dash bits - that's part of the reason I called out that I've not done to work to map those connections. I could do it pretty quickly if somebody wanted to check it out on their own car but I don't want to go down that road with mine since this is already taking for damn ever.

I believe somewhere in this thread: One bad Z4M.. in progress.. https://www.zpost.com/forums/showthread.php?t=630093 they where trying to get either a Pro-efi or AEM stand-alone then had to change because it just wouldn't work with the car, they finally said they got some unnamed standalone to work in conjunction with the stock dme in the end. Might be worth looking at

Interesting, hadn't seen that thread before. They gave up too soon on both the AEM and Pro-EFI solutions, IMO. I don't blame them, to be clear, but this cloak-and-dagger nonsense that tuners and manufacturers pull just irritates me. The only difference between the Z4M and E46 M3 from the Infinity's perspective is... nothing. Since it doesn't try to interact with the DME itself and all of the body modules it cares about are identical so far as I can tell, that shit Just Works(tm) if you wire it properly. The engine / chassis harness for the DME uses different connectors but again, so far as I can see, all of the same wires and signals are present, they're just laid out differently with different colours. Electrically it's the same vehicle.

Once I've got this running as a full-standalone setup, I'll be happy to help somebody take a crack at using the E46 M3 harness / Infinity unit. Should be pretty straightforward compared to the rest of this.

It seems like it's just different color wires then the e46 but no one wants to spend the time/money to look at diagrams and connect everything. Similarly it should be same as the e46 dme as you said. I hope you keep track of every connection to setup the AEM, because if you do you can make a good buck and help a lot of people out on this platform in converting over. I do know HPF got two pro-EFI system to work on two Z4M's.

Well, the DME is completely different, which is the thing. Interestingly, a lot of the wire colours are actually identical. It makes some sense considering that the engine-side loom is identical, wouldn't have made any sense to assemble that side differently. That being said, I've already encountered a couple of oddities in the DME loom that strongly suggest assembly-time adaptation of the harnesses. Which is kind of cool.

Started by disassembling the DME connectors. They're actually a handful of connectors inside a housing, so a little screwdriver and a few minutes and suddenly things are a lot easier to work with:



Started with the coils since I'm not just adapting the harness there, have to put the ignitors in the mix. I figured this would be a reasonable place to mount the ignitors:


And then got everything wired up:


And that's as far as I got so far today. Protip: try very, very hard to use similar colours when mating a factory harness with a new harness you're building. Because I was doing that, I caught a mistake I made in the wiring diagram (yes, I am keeping as-built notes and will update the diagrams later on). Took 5 minutes to straighten out instead of the hours of diagnostics it would have cost down the road.

Phew.
