Andrew's S54 Swap

[FredK]

I didn't see a DSC delete from Evolve? Deleting post cat O2s, switching to "Alpha-N", US tuners have been doing that for a while.

I really dig their carbon airbox, though. It's inexpensive given the tooling, manufacturing costs, and market timing (towards the end of the S54 lifecycle).

keep reading. the computer systems on the E46 all talk to each other. so if you're removing the ECU from that environment, it's going to throw a lot of errors when it can't communicate with the other modules. Most likely it will go into limp mode.

Well said, thank you :-D

And a reflash is necessary because...?
Doesnt that delete EWS which has been established that is not necessary?
Or should I just continue reading and stop posting?

[nando]

Why is this?
What necessary programming is needed for an S54 to run in an E30?
It's already been established you don't HAVE to delete EWS...
What else?

you know, people are willing to help.. but you need to do some basic research if you want to be taken seriously.

basically, if you have to ask... you know where I'm going with this.

you can get flashes for much less. any of you guys hear of Evolve? you get a flash cable and a tuned file for $999. and you can upgrade the tune later or transfer it to another car for under $100. for $3500 you also get a CF airbox. :p

I think that's a WAY better deal than $1500-$2000, to mail your DME somewhere, get a black-box tune from some random dude, and then be pretty much stuck with whatever you get.

[FredK]

It is because the reflash is fairly pricey, around $1200 at current exchange rates. A DBW accelerator pedal is around $100 new, and the various wiring components will run around $30++ depending on where and how you get your components, new or used, and the grade of wiring you choose.

[lolcantturn]

Having done a Euro swap and an S54....the S54 is another order a magnitude in cost over any other swap if done right. The electronics that need to be addressed will cost at least $1500 and up.

I like the garage although doesn't it get cold in the winter?

If I gave you a complete parts list then you wouldn't have any fun. :D

WORD. I agree :)

I guess we should take down the 24v swap sticky:p

So clean, you made it look easy with this thread. Really great job. Enjoy the car and post up lots of videos!

[RobertK]

Can't hurt, but I'm sure you wouldn't keep driving with a low oil pressure light on like the dumbass who drove my car did. ;)

Very nice clean swap.


A little word of advice though.. If you ever have to remove the pan I would rethink the oil pump nut reinforcement. I used to think it wasn't necessary until I encountered this..


Its not the torque that works it loose its vibration from the harmonic balancer over time that eventually fatigues it and 1 hour worth of installing a safety nut / tack weld > rebuilding an oil starved engine.

That can't be good. ;) I've heard the sprocket nut on euro S50/S54's is less likely to come loose but I might do something about it if I ever take the pan off again. Good tip. :up:

Exactly. Do the legwork and it's so much more rewarding.
