So the SDS can or cannot control double vanos properly?

I ask because the boss wants the double vanos to work on the S54, and the best setup to run it is Motec for ~10k.

I haven't put much time into engine management research at this point, focusing more on the physical/mechanical parts to get the engine installed in the space provided.

I had the vanos working with the sds, but it seemed to make less power, so we are taking out the vanos all together for the S52 cams.

why don't you run the stock management on the S54? Do you have a wreck e46 m3?

You can't run the stock MSS 54 engine management. EWSIII along with a ton of other issues render it useless. The only way it would work is if you took 90% of the cars wiring, sensors, and computers and shoved them inside the e30's dash. Most of the systems communicate on a bus through the instrumentation cluster as well.

It's already going to be a trick and a half to get the SMG working. If that fails I will just remove the SMG parts and convert the transmission back to the 6spd it was born as.

JazzM here has swapped an S54 into a Z3, using stock engine management with a MarkD chip.

I know that most of the cars management would have to be used including the EWS.


How about a euro spec S52 e36 engine management, I wonder how that would work with the S54??

I still think there will be problems with the smg if the dme is not used etc.. Maybe your best bet is to just use the 6 speed without all the extra pumps, lines etc, plus the SMG doesn't shift much quicker anyways.

The SMG is purely for "look what we did" factor. This is a showcase car.

The S54 E30 around here is running Motec I believe.

A cheaper route would be interesting.

Who has a S54 E30 in the GTA? That would be interesting to see.

Unsure of the owner, but Mike at Munich Motors completed the swap.

It was an older Z3, with the 2.8 in it at on time I understand

S54 -> E36 is much more agreeable than S54 -> E30, just because you can use the M Roadster parts (ABS, cluster, etc) easily.

Some specs:

2000 328I Motor with double Vanos.

Thanx
FYI, you may want to look at getting an M52 non TU engine. You can squeeze about 210 RWHp quite easily out of it with M3 cams, M50 manifold and some software. I've seen these go up to about 230-235 RWHp.

The problem with the TU engines is that its hard to mod and more expensive.

Mine's a 97 2.8L originally now with an S54. Your main issue will be getting the engine management working. In my case I'm using the orginial ECU (S54) and using the 2001/2002 m roadster ETK I've rewired the engine harness to body accept full body electrical integration. I can go to the dealership and they can diagnose the car fully including the 2004 M3 ECU and the 1997 body control units.

There are some serious issues to overcome. First and foremost is the EWS imobilization system. Your engine will not start unless you have a coded key, key reader, EWS and ECU matching.

What other's have done is simply use aftermarket engine management which gets rid of the dual vanos. In my opinion you will not have a usuable powerband like you would with the VaNoS enabled. The M3 unlike other BMW engies can adjust the VaNoS timing by as much as 40 degrees. Other BMW models only go to about 22 degrees. You're only going to get that tunning if you use the orginal ECU.

The next issue to overcome is the drive by wire throttle, those that go to an aftermarket ECU get rid of that too and replace it with a cable driven pedal. Again, mine has full drive by wire throttle which is adjustable in the ECU tunning.

Furhter you're going to run into issues with your fuel pump, fuel filter, etc. etc... It took us about 8 months to figure out all of BMW's wiring.

This winter I'll be adding DSC and ABS to the car and I'm currently researching converting the 6speed transmission to SMG (they are identical as we've rebuilt both types already). Only difference is the hydraulic gear selector/clutch and the control unit.

FYI, all comunication in the new generation ECUs is digital using the CAN+/- bus vs previous generation analog signals. Hence for example the cluster only connects two wires to the ECU to get the speed, rpm, error codes, temperature, etc....

Good luck and I'd like to hear more about your project and how it goes.
