What if one has MSS54? Would we need to buy a MSS54HP DME?

I think you do.

Terra, if we don't want a flap, do we have to do the h-bridge solder thing? Or is that a thing to make the map sensor work?

I don't think you do. When I researched its only done if you wanted the flap.

You can solder the larger flash chips to the DME and run the CSL software with that. Though my preference is to have a real HP.

Edit: Forgot to mention, there are two resistors that need to be changed if using a MAP sensor on a non-HP.

H-bridge is only needed if using a flap.

Thank you Terra, so again, in non-computer person talk, if I have a MSS54HP (11/2003 build), I could simply load the CSL engine management and get a map sensor and csl IAT and take care of the vent lines?

Thank you again

Pretty much, though loading the CSL software will either require MSSFlasher (which from what I understand is down at the moment) or a BDM flash.

Doesn't necessarily have to be CSL IAT, it's pretty easy to rescale the curve for other sensors.

Default Re: CSL intake question

Okay,

So here is what i got so far. I am trying to make this as easy as pie. Trying for mostly plug and play or something already modded and sent to me

CSL instake with karbonius
Map sensor - either
https://store.langracing.com/s54-map...fi-conversion/

or

http://tuningtechfs.com/ttfs-e46-m3-...nd-map-sensor/

I am iffy one splicing wires because thats permanent but when i hear the noise of the CSL air box i just start drooling.

DME
http://www.ebay.com/itm/2004-BMW-E46...1Z0wZA&vxp=mtr


-------------------------------------------------------------------------------------
Relocate brake booster line with appropriate tubing
Extend crankcase vent hose with appropriate tubing

Add-on which are not essential but (somewhat) recommended:
OE CSL Brake Booster Valve
OE CSL Vent Hose

Do these two parts above take care of the "appropriate tubing" part of this or is there an OE part i can get?

You don't have to splice any wires at all.

You can instead de-pin the connector at the DME. That way you're not irreparably altering the OE harness. You use a pick to remove the original IAT/MAF wires from the DME connector, making them unused and unpowered. You then install your new MAP and IAT wires in their place in the DME connector.

It sounds more complicated than it actually is-- takes less time than cutting and splicing, is much cleaner for troubleshooting, and can be reverted back to original condition if/when that matters.

I wouldn't worry about splicing wires. You can get a complete stock harness pretty cheap, and it's surprisingly simple to replace when you've got the airbox off anyway. So if you do decide to go back to stock, you can always just replace the engine harness

Those two parts do take care of the "appropriate tubing"

CSL intake sound is addicting.

Like the CSL gurus here said, don't worry too much about the splicing etc, you don't have to if you don't want to. You can order the "connectors for DME" and all other associated parts from the list in the picture below (pictures / instructions borrowed from M3forum and it's awesome members).

One piece of advice though, you'll be 90% there so please do yourself a favor and have a working flap. The sound / emotion generated when the flap opens at 3,500 RPM is truly something else. Watching the flap open when you're showing your family / friends etc has a c
