Coming Soon BMW SOFTWARE UPGRADES

[Carma]

Carma has ordered a great new diagnostic tool. not only will this help us with diagnostic work, it also will code all control units, and most importantly IT WILL ALLOW US TO REPROGRAM YOUR BMW. I saw a rear wheel dyno graph and on a 2000 M3 they were talking about 28 rear wheel horse power Unbelievable. Should cost about 500 or so per car. Totaly reversable and best is that it will NOT cause any emissions or check engine lamp problems. Hit us up to save a space to be one of the first.

too expensive

[HiRide]

Actually, depending on the car $500 is a pretty good price.

For an e46 M3, the usual price for a DME tune is between $600-$800 plus shipping the DME out and back.

Also, getting it done locally means not having your car out of service for a week, again atleast for us e46 M3 guys.

they did not make BMW M3's in 2000 and 28rwhp out of an S54 without a dyno is completely unrealistic.

[BATMOBL]

true dat abt the 2000. but 28hp is realistic thats prolly a little too much advance timing to make me feel comfy tho specially with the high compression.

The would mean an E46 M3 is making upwards of 300whp with nothing but software. Thats possible with just headers and tune though.

Those were dyno runs from a UK shop. The car was a 01 M3. Sorry for the confusion. It did show 28 rwhp gains. The X5 we did yesterday felt must fast on first accleration. From a dead stop the initial torque curve is much soon.

lol... seriously you should buy a honda then.

500$ is great deal for ecu reflash

[HiRide]

yeah, especially for a BMW... but 28 RWHP on pump with no modifications is unrealistic.

Also headers and a tune on an e46 M3 will only give you about 20 RWHP if you are lucky. Most of the popular tunes are primarily throttle mapping. [re-mapping the fly-by-wire throttle pedal vs. throttle body mapping].

But that 28 is also on a Euro Spec M3. they have a different exhaust setup from us here which gives them the 343BHP numbers. Now that being said, the euro version only puts down only about 7 more RWHP... but can gain 20 RWHP in the US with headers(with no cats in them) and high flow cats. So they are obviously not coming tuned to take full advantage of their better exhaust system.

that being said, they just might be able to squeeze 28 RWHP out of a euro motor with a hellacious tune. I agree that is probably not the safest thing in the world.

A US spec S54 in an e46 M3 will gain no more than 20 RWHP with a maxed out tune of fuel, ignition, AND vanos. Vanos tuning counts for half of that gain alone... and its not easy. its one thing to tune simple variable valve timing systems even the earlier single vanos is easy. Pick the two different timing settings and the degree at which you want it to change.

But the S54 has Dual Vanos... This system is constantly adjusting over a 60 degree change based on airflow and throttle. And its two separate cams with separate movement. So now you have to tune the intake cam on a full map table for each load point, and then do the exhaust cam and tune them against eachother to perfect the overlap. And more than just peak power, proper vanos tuning can create gobs more torque in the low end, which this car really needs.

So in order to do this correctly, the tune would have to be done with a beta car on a dyno for well over 10 hours. And after all that I would not want my stock motor pushing that hard, so the tune should be backed down a notch for reliability purposes which is basically pulling a degree or two from the timing. That should still leave a safe 15 RWHP which is actually still a good deal in the e46 M3 world for chip tunes.

Carma should put up some dyno sheets of before and after so people can see the actual change. This is the beauty of a local shop doing in-house tuning. You can see the difference in front of you. Unlike many big name chip tunes that claim HP and do give some through leaning out the rich spot above 6500 RPM adding a degree or two, and then the rest is throttle mapping without touching the vanos which would take a lot of time.

Heck, i slapped a piggyback on my S54 with complete and independent control of fuel and timing... no vanos control. and picked up 15 RWHP at the peak. However I also have full bolt on mods.

What "device" are you using to tune exactly?

scroll to the bottom one. They only have a few posted. I have done a bunch of E38 from 96s to 01s and a few late 90 540s.
It's nice to, since when I did my wifes 740il it even included deal updates to the software. That way not only do you get a better map, but if BMW has posted some software updates for this or that, they are included in the downloaded bundle.

It is even reversable.

[Gilgamesh]

so what is this shark edit crap thats coming out?

[HiRide]

dont know when shark edit is coming out, but it is looking to be more of a pro tool than DIY tuning software.

Still, it should make for some interesting tunes on the e46 M3 as well as other BMW's. It is really going to be interesting to see how this effects people selling DME tunes.

honestly I think that most people will get the large name tunes for the ease and "safety" that comes with them. at least a lot of experience. But I am curious to see what some more aggressive tunes will do besides blowing up people's motors.

[Camrazy2102]

what about for E38 740il, do you have graph of how much HP gain?

[Logan]

Hmm what kind of cars is this compatible with?

I have a 94 540i

[kerndog8]

haha, what ever happened with this?

[DinanM3atl]

It apparently 'works' but don't know all the details.
