S54 making the jump

[hoveringuy]

The only reason I would want an M54/S54 over an S52 is because of the dual VANOS (and the aluminum block on the M54). Why does everyone keep talking about locking out the VANOS with standalone?

I want to run the stock ecu and keep the VANOS.

The M50 was a big mystery until everyone put some effort into learning it and making it work in the e30.

The M54 is the next generation and I'm sure we can tackle adapting it into the e30 without standalone management.

Is it too early to talk about N52?

Ive been thinking heavily about this swap too....

Whats with everyones "just do an euro s50 swap" bullshit? I want an s54 damnit not an s50us or s50b32.

If Vanos is not a problem, solved by just by-passing it, then I think this swap truly shouldn't be a problem. Any sort of capable EMS can run a motor without vanos.

Who is running an M52 with factory ecu here?

I'm not talking about a standalone system or a race motor. I would only be interested in the M54 if I could run it with the factory ecu. Maybe I'll get frustrated enough and design/build an emissions emulator.

Find the Polish guy on here who did the swap. He should be able to help you out. Plus with the m54's small intake manifolds, you can get a bigger brake booster along with bigger brakes. :D

If I just had the other half :(

As you've read its being done in America too....

:pimp: just a little something lurking around in the garage


Check out those ports

Just to get you guys thinkin:)

What about stock ecu? Keep the VANOS and the factory mapping, plus IT'S BEING DONE. In Poland. WTF?

does anyone make a vanos delete similar to VAC's piece for the S54?

Who cares? Do it right or don't bother.

If you just want an aluminum motor and don't care about vanos, get an Al M52.

Why is everyone interested in using the Autronic units? They are kind of outdated. A much better option would be the Pectel units. I know the Pectel S6Q (or is it SQ6) is able to fully control an S62, including the electronic throttles and all 4 vanos units. It is also able to do full sequential. The Pectel units are also about the same price as a fully unlocked Motec unit.

I would rather have an M54B30 than an S54. They have very similar performance up to 6800rpm and the aluminum motor is lighter.

Just a thought...

Kristov,

Are you utilizing the factory ABS, or did you eliminate that all together? I would like to keep the factory ABS intact as well if at all possible.

So is the speed calibrated through cable or is it a wired sensor on the S54 trans? I kind of figured the VANOS would have to be eliminated, although that's not that big of a deal. For the tach you just use an output from the Autronic to the factory cluster and bypass the computer all together? That would seem logical, I know these may seem pretty goofy questions but I am used to VAG products and their electrical is pretty rough on the newer cars.

Do you have pictures of your set up? I would like to see it for motivation. ;)

I have retained factory ABS - it is a standalone system and does not rely on the engine ECU.

Speed-signal goes directly from the differential to the cluster - no need to do anything there.

VANOS can be controlled with SM4 - I just think the gains are too small to rectify all the hassle with setting it up and extra work adjusting it afterwards.

Take tach signal from SM4 and just splice it into the factory wire for the tach on the cluster.

I have completely removed the original ECU.

I will release some pictures when it is done.
