E46 Engine Management Options?

I recently picked up a 2002 325i with the sport package and I'm pretty impressed with the overall nature of the car. However, I am coming from the high strung 4-cylinder world and this meek power output is, well, a serious let down. The larger motors still aren't enough to get my power fix, and I don't see a tapped out N/A setup being anything close to what I would like.

I've built numerous custom turbocharger systems so the fabrication of a custom turbo kit is not a problem. The only issue holding me back from turbocharging this car is the engine management. I don't want to jump into a project that I can't control the engine when it is done. I also don't care for others tuning my vehicles as I'm fairly competent in tuning engines when the software is available.

Is there any software available that will allow the user to tune the fuel and timing maps? Searching through there, it appears the only thing offered is supercharger kits and that does not interest me at all. It doesn’t look like there are any options, but I thought I would just ask incase I missed it some where.

HorsePowerFreaks/Technik (e90, maybe e46), AA, and DA Motorsports all have turbo kits in the works, so it's a waiting a game if you're looking for a kit. Hopefully they all come out this year

I think a few people on here have some one-off kits using motec management or something close to that.

I'm just interested in engine management.

I've got no problem building the turbo system. Just need to be able to do the tuning on my own. Here are some systems similar to what I am talking about.

http://www.hondata.com
http://neptune.evans-tuning.com/
http://www.dsmlink.com
http://www.tunercat.com/tnr_desc/do_tc.html

Is there anything like this available for the E46?

Look for a company called Sias Tuning (I think). The guys name is Vic Sias, he posts more on Bimmerfortums, but he sells the ECU system most E36 boost guys run - the TEC 3, it has VANO's control, not sure if it is double VANOS capable or not, but it is the best stand alone system I know of. If anyone can help you out with it its probably him.

I tend to prefer Motec or Autronic if I were to go that route. But I want something that I can pass emissions with legally, well, mostly legal anyway. Rewiring the car or building some hack of an adapter harness is not an option.

I was more looking for a hacked OEM ECU that allowed you to do your own tuning. If these companies selling performance chips are really doing as much as they come across as doing, I'm surprised nobody has gotten out there and released the software needed to hack the ECU fuel and timing maps.

Most people will still pay the professional for tuning, but it gives some of us the chance to blow up our own motors.

You do know the differences between the systems, right?

Engine management is the single most important factor on a car. I'm surprised to see a car enthusiast board that hasn't gotten around to hacking the ECU so everybody can tune their car.

THAT is when the real progress happens. You can buy turbo kits all day long, until you have the ability to control fuel and spark, you won't get any where. Paying a professional $500 to flash a generic program onto your ecu isn't tuning, it's highway robbery.

I do not want to hear about SC kits or Turbo kits for E46. They run at the car price. It doesnt make sence to spend 8k cash on 325i and to spend 8k on the supercharger. For 16 k you can own 335i or if you love the body you can have e46 M3 in fair condition.

What I want is to built my own turbocharger kit from parts like used manifolds and used turbo possibly all in good condition. Run an engine management under $-1000 .
Those supercharger companies that monopolized the business say that ebay parts are crap, well I dont need a cast iron manifold with HPF logo on it for one grand if i can buy the same cast iron on ebay for 100 buck.

YOu have an option too. You can pull out all of the BMW's wiring out and throw it away. You dont need half of that with turbo set anyway. Engine management will need to know your sensors that is it. Your engine throttle position and your ox sensors.

I am thinking if to buy an e46 part car for the project. The first with what i will start is ger read of all the stupid computers . then put my own systems. Who cares if you will not have DSC and all of the rest of the crap like voice dial and instrument cluster.

This.

Put your money (or lack there of) where your mouth is, and show us how it's done; don't forget your dyno.
