S54 swap?

[MarkD]

I worked on the software for an S54 into E36 swap in 2005, who can beat that one?

And I have an E30 racecar with s54 swap running in Toronto right now.

Nice project!

Bear me in mind if you need a way to get the engine running oem style.

Mike from StanceFactory up here in Toronto had his S54 E36 running for a while, I think last year it was. I heard it was before Burroughs, he was down at H20. He's running all factory wiring and DME's everything works, even sport mode.

if it handles like its "on rails"..... You're not driving it fast enough. :)

interesting that the s54 swap is becoming more and more common..

Interesting

Has anyone thought of just using megasquirt? I think they should be able to control vanos by now?

If you had even a slight idea how good the Siemens MSS54 ECU is, you would never suggest that.

I will know how to do it soon. It is my current to-do task.

Soon could be relative. The sun will explode soon, in the grand scheme of the universe.

I've figured out how to do it, just have not released any kit to do so. My method requires a software update plus either a hardware mod inside the ECU, or a a small circuit outside the ECU.

Then again my swap car was pretty dialed in, and it handled on rails. :nice:

son, you got to dial in a little more "right foot!" handles on rails...... with an s54...... sheeesh.

DTA ran s54?

Stock e36s are pretty fast. I'd put my stock 328is track car up against most of the swapped cars on here even though it's 3000 lbs.

I'd agree with you. Most of the swapped cars on here don't have very well sorted suspension set-ups. Without dialing it in probably the added weight of the motor over the nose, and the added torque can really turn into a handling disaster. :p

Yeah, a gutted E36 with a lot of tire can be very fast. Add an S54 and it is even faster.

[Jean]

e36 with s54s can be fast!!! look up Vic Sias's autocross e36 car with s54.

We've developed these side by side, but they're not identical.

My headers and intake are probably flowing better than Jason's, only because I had invested long ago in a set of euro stock headers, and I'm running temporarily the CF clone of the airbox.

That having been said, Jason's car would cream mine even if I have a few more horsies, his car has better weight balance, and best of all WAY LESS weight.

I'm running AC, full stock E36 interior etc....I'd have to guess his car is near to 2200 lb, mine closer to 3200.

No comparison for the actual cars....And any of you dropping same motor into an E30 will also realize the benefits of less weight.

Oh sounds good. I'm sure the car still pulls hard for an NA e36!

Quiet that exhaust down, you need to be able to hear that airbox scream!!! :hitler:

The VANOS is the easiest part to control on the S54. 10X easier than the M54! No PWM is even required... With two solenoids per cam one is the "fill" and one is the "drain". Fill until you get the right position and stop. The cam is hydraulically locked in that position until it's moved again.

As far as Megasquirt, yes it can be done... the challenge on the S54 is that the cam sensor wheels on the S54 look much different than what we're used to on M50s.

If I ever get my hands on an S54 I would like to adapt my VANOS board to both control the cams AND to translate the s54 cam signals into M50-speak so that Megasquirt/413 ECU's could run it.

you could change the cam signal on the S54 to basically whatever you wanted for MS. a missing tooth wheel pattern would probably be best. or supply the developers with the required information and have native support. :)
