Not really, as with any computer the ECU can only do what it has been told to do, i.e. how it's been mapped in the latter case.

For example on a cold start MAP you might have a temperature range and then a fuelling table which says for xx °c give an injector pulse for x milliseconds, I have put this simply there is alot more that goes to actually achieve what it does.

So if it is poorly mapped (not saying it is) it will simply act on what the MAP says, you can now understand why it's very dangerous for someone to play with maps unless they are 100% compentant in what they are doing, especially with a FI engine as with boost you can end up with a meltdown very easily.

With adaptive ECU's they will make slight corrections where they can and store those in memory for optimum running conditions.

If you have a MAF sensor then you also have aftermarket sensors, as these cars have MAP's.

Back on subject like I say, set the base idle correctly as that is far to low!

That cannot bve right what they are saying re the ECU, thats a basic function of any ECU or car infact for it to start!
