That's nothing to do with it either in that case, as boost levels are already configurable to exceed 28i levels-there must be something else that's affected?R.E92 wrote:Processing power has nothing to do with it. The processing requirements of an engine do not increase as the power output increases. The DME is just telling the plugs when to spark and how long the injectors should stay open when spraying fuel, no additional calculation is needed for the higher power output of the 28i.Smartbear wrote:It's already possible to get the 18i remapped to a higher output than the standard 28i.R.E92 wrote:
I doubt that the power of the DME module has anything to do with it. It will purely be the code that runs in the module that differs.
It's not as simple as just replacing the DME with one coded for a 28i as BMW have put measures in place to prevent that. I'm sure there is a method to circumvent this but beyond the reach of most people.
The best bet is for someone to reverse engineer the DME code like people have done with the N54 in the 35i and 35is. The N20 engine seems like a perfect candidate for the likes of Martial at MHD. If the N20 becomes popular for tuners then I'm sure it will happen.
I don't see why people get so upset about getting a de-tuned engine. You guys should be happy, you have an engine which will probably never go wrong since it's only running at 70% of its rated output.
Also there is the possibility that someone puts to effort into cracking the N20 DME and you guys have yourself a hugely discounted 28i.
I think the difference between the dme's is in the processing power, the light weight version probably can't support such sophisticated mapping & falls a little short because of this? (Just guesswork on my behalf)

The only difference will be a set of registers within the software which dictate how much boost the car targets.
