Which ECU Tune??

Or by just changing the temperature compensation maps or turning off the fault codes.

You cannot make the DCT run cooler unless you fit additional or better oil coolers like the race cars have.

You can keep clutch temps down and avoid overheating by allowing the clutch to engage faster.

^ +1. I want that software badly.

turning off the fault codes is not the answer. that's a good way to hide problems that can lead to failure.

Working on something now. I'll have more info to you in a few days.

You can go slightly leaner and gain a small amount of HP but it's really not worth the risk.

Any tuner who logs EGT's on prolonged high rpm full load driving will know not to do this. For the sake of a dyno run... it gives more power until temperatures start rising.

If the AFRs are staying the safe, the power has to come from a more aggressive ignition map, no? How much more timing do you guys add to the map?

He said they mess with cam timing not ignition timing

OE hands down...He tuned the highest HP cars with SC stg3s in the US. Numbers and vids coming soon ;-)

Is this what OE is doing in order to maximize the power put down on their dyno?

[niterider]

OE logs egts. My cars egts are still safe to track even though im making almost double the Hp of what my car came with from factory and I run on pump 91oct (garbage) and meth. EGTs are main concern when tuning these cars.

No! OE tunes have shown power gains on dynos across the world, but most importantly the drivers actually feel a difference when driving their cars on the street or racing at tracks.

I can feel OE tunes improvement over stock

I do.. in both my cars.<3 it

OE tune, what is the full name OE?????
Where can i find it????

Negative...

Rather we use a blend of minimal ignition changes combined with changing the valve opening and closing event (Cam timing) and changes to the torque calculations so everything is balanced.

A little more finesse than brute force

Oh, and the evolve-R just makes everyone's life easy at a reasonable cost.

car was very quich for an NA car,smooth and idle a lot better than stock from start up to a complete stop @ a stop sign.

Are you saying that you gained 26whp after the tune AND all the bolt-ons together or 26whp on top of what you had already gained with all the bolt-ons ?

Got all the bolt ons installed and Dyno'd the car,2 weeks later got an ESS NA tune then went to the same Dyno and put down 26 WHP more.

That's awesome! Thanks.

More misinformation from the king of it.

BMW has no protocol to proactively look for tunes, so you would need to give them a reason. So the "always" statement is false. They actually sell Dinan tunes at my, and many dealers.

Flashes are reversible; some in 15 seconds, others require more work. So the irreversible comment is also false.

+1^,you are correct Sir !
But even once reversabled there will be a trace since its stored in multiple places in the ECU and as you mentioned "you need to give them a reason to go in there and search for somethin/clues"

Leaning out AFR is a huge misconception and a generalisation.

Yes, if you have a car that runs from somewhere in the 10's-high 11's, leaning that out to anywhere between say 12.2-13.0 will increase power.

This is used to be the case with much older cars and some modern cars.

Here we are going leaner but we are going from silly rich to AFR for best power.

The lambda target @ WOT for an MSS60 is set as from 13.6 (1000rpm) making it's way towards 12.5 (8500rpm).

Now that's very good for achieving best safe power already and more importantly, consistently.

Leaning out at the higher rpm will only give you a temporary increase in power and even then it will not be much. Even if there was a genuine power increase it's so small that it's just not worth doing.

Ignition timing of course always gives power but the MSS60 already has some pretty radical ignition targets for a stock car. You can see from a recent dyno day that we don't actually run much ignition timing over stock at all. I mean, the ECU is already targeting 32 degrees at WOT high rpm! How much more do you want!

On another post I have shown the full throttle target for ignition (stock). So you can make your own mind up from there if you want to add, or if it's even possible to gain, massive power from ignition.
You can set the targets to what ever you want, does not mean they will be achieved but it's not the best idea in the world to raise them too much.

A combination of CAM timing, ignition timing and changing the allowable maximum torque (these are calculations) gives a very nice safe power increase.

Just going back to the ignition timing again. Even though the targets are set pretty good in the first place, it does not mean that the targets will be met. To make more power more of the time you can 'force' the timing. You have probably seen one other tuner mention this also. This is done by increasing the preset ignition maps.

Some say it's a bad thing, some say it's fine but it all depends on where these maps are preset to. If it's very close to the targets then you already know what's going to happen!
