I dunno about you, but that dyno graph looks pretty strong from 3250 (probably where they went WOT) to 8500 RPM, and the particular example has locked cams. I may not be able to duplicate the power output figures, but the overall shape of the curve would remain very similar on a stock engine.
It would be ideal to get an EMS that can control VANOS. There are three that I know of so far: Pectel, Motec, and EFI Technology. What it boils down to is
a) how good the support is (factory, tuners in my area or at least on my coast)
b) how easy it is to get the car safely running
c) cost

Yep, that was what I referenced--the MITE46 swap earlier in this thread. That doesn't seem a half bad way to go, after thinking about aftermarket EMS for a little while. With a stock ECU, you have the benefit of the fuel and ignition maps exhaustively tested for everyday, reliable driving.
I've decided against doing the swap this winter, mostly due to time and budget constraints.
Maybe if someone local wrecks an S54 Z3M and sells it cheap, I'd pick it up just to hang onto it, but otherwise, I'm just gonna lay low and read ETMs until the cows come home.

exactly that is what i think about .. if you swap the whole engine with the electrics and everything related to it , it will be good for daily drive , also with the same specs and so on , i mean see what the donors car diff ratio/lock was , build in a same one .. see what brake rotors measurements/brake calipers were in , try to build them in too or build something similar , .. etc ..
then you will end up with a good dailydriver .. (if you find a Z3M donor car , tae all the mechanism and electrics , everything what you can get ..
i always read , the whole rear axle suits in the E30 plug n play , drive steering column fits with little work , and is directer , you can even make the 5 lug conversion with the front axles ..
related to electronics , take everything what is attatched to the wiring harness , including speedometer and everything ;)
easier .. buy the whole car , buy a E30 2 door for cheap money . and start rebuilding the E30. fit the "whole" wiring harness from the Z3M , and then you dont need to play with the engine wiring harness and so on ;)

That would be really expensive, more or less what MITE46 did.Rollin' with a Geistkuchen

I understand from reading all the way this thread that the main problem with the S54 swap is the DME and all the extra things BMW has it do besides engine management. Hasn't anyone tried to decode the function codes and come up with delete features or something similar? Seems like there is a market for such a thing.
I know it took several years to break the Honda codes, but now that they have there are several firms that offer flash programs, etc for just about any combination available.
