Stand alone engine managment for M50 engine.

[lukasbmw]

My modded m20 engine never ran up to snuff because I never took the time or money to setup an engine management system. Now that I have an engine I actually care about, I'd like to see it running at an optimum air/fuel level at all times.

Can anyone recommend a kickass stand alone engine management system that will allow my M50 engine to be tuned for modifications?

Split Second?

My neighbor's E30M52 is fucking mean.

I can't remember what he uses off the top of my head...SMZ? SMT maybe? SMS?


I'll ask him tomorra.

MoTeC m-600 ... probably the best you can get...

You are going to have to pay dearly for something that can tune the vanos (unless it´s on off system)

Also you are not going to need a standalone unless the stock system reaches it´s limits
for instance you need to change the timing system for diffrent purposes,
out of this world power,

A piggyback system will do well enough for a M50 thats not for track use,

With a SMT6 unit you can tune, Fuel, Ignition, Fans, shift light, boost control, NOZ control,
You can run any size MAF/HFM, any type Intake manifold, exhaust manifold, turbo/turbo´s/SC, any injectors, on a 6cyl engine you can run 6 extra injectors apart from the stock ones(12 total)(any size injectors only need to be 16ohm each),
You can use a semi-wide band to tune the fuel or a narrow band(altough the narrow band aint really quick enough but is good refrence when doing steady accelaration)

There are plenty of stand-alones on the market that would work: Simple Digital Systems (SDS), MoTeC ($$$), TEC, etc.

If you're only mildly modding the car, a piggyback of some type would probably be best.

Remember, whichever system you choose is only as good as the person installing and tuning it. Ask around area dyno shops and see what they have experience working with.

electromotive tec-3. talk to vic sias, he be da man. MoTeC might be a little much for a street m52...

Lukas, that was the one thing that bothered me about your engine work on the M20. I would have hoped you would have seen more gained if you tuned it right. Like you said, the parts seem to have gotten each other "confused" or just de-tuned.

What all is done on the M50? M3 Cams, right? What about the TMS S50-cammed Chip?

[Z3Jonathan]

Engine management modifications really need to be in proportion to engine mods. Sure you can put a MoTeC on a stock M20, but you're just pissing in the wind on that one.

For mild mods, you could probably get away with sizing injectors and a fuel pressure regulator. Maybe have a custom chipped burned. If you get a little wilder with the mods, you can go for something like a Megasquirt, or other piggyback system. If you start looking at turbo/all motor setups, then a full standalone is a good idea. If you're doing purely track work, then something like a MoTeC.

There's always exceptions to the rule, especially when you consider budget.

I would suggest Electromotive or SDS for a quality mildly expensive engine management, they do full fuel and ignition management. Motec is QUITE expensive, if ya wanna go that route, ya can, but you wont be using the full ability, so you might just want to stick with the Electromotive or SDS.

Megasquirt. I have it. Its cheap. It only does fuel. It works. Did I say it was cheap? It is actually standalone, but only does fuel, unless you get Megasquirt 'n EDIS, or Squirt 'n Spark. It supports laptop or palm for tuning. If you are good with electronics (soldering/wiring) I would suggest this, because you can keep the price under 400 bucks.

Insert fast and furious quote about spending 10gs on stand alone engine managment.

what about overnighting parts from japan, err, germany?

I really don't see that you will need a stand-alone system. The piggy-back units offer enough for NA mods and even turbo mods.

I chose the Unichip piggy-back since friends used it with great success. It is professionally installed, dyno-tuned & you get a before & after dyno run to see results. On our strokers it gave us appx 15rwhp & 14rwtq extra just from the tuning alone. I'd recommend it to anyone.

For more info visit their US website at http://www.unichip.us/index2.html The site will show dealers in the US.

I like the Haltech E6X set-up. Its not that expensive compared to other full stand alones.
