Switching betwen two tunes in Motronic 7.8
I´m a bit confused so I´d appreciate a few pointers...
I am now a bad boy and run catless, the car has a custom tune for my setup (Motronic 7.8). This summer I´m going to Nurburgring and I cannot run catless there, the german laws are too strict, I´d be stranded if the police stopped me. So, I need to run cats and need to redo my tune/mapping, I have a great tuner so if will work out. The car runs and sounds amazing right now, so it feels a bit sad to go back to oem 400cel cats (Only one set of cats on my German import car). So I see two options: 1) Fix some high quality 200 cel cats 2) Run two separate setups: a) oem 400 cel for Nurburgring and MOT b) catless when I feel the need for speed. ;-) Alternative-1: The big issue is to find a good quality 200-cel setup, so good quality that I will even be able to pass MOT, I actually cannot seem to find anything on the market, any suggestions? This + a new tune will be quite costly and I guess I´ll get drone. Also, 200 cel will still not be legal in Germany, but I´m sure a lot less offensive than running catless. Alternative-2: No problem to get a new tune for the oem cats, but when switching between the setups I need to get the different tunes installed each time, and my tuner lives in another city. Would there be any possibility to switch tune easy? Like dual Eproms or something? I don´t think there are any cheap software solutions, but maybe I´m wrong? Ok, there is a third option, going back permanent to oem cats, but I´m pretty sure they are restrictive, so it doesn´t really do it for me.. I hope this wall of text made any sense... :) |
I'm actually considering sticking to the oem cats, guess I'm getting old.. It would solve a lot of practical issues.
Do we really know if and if so how much they might restrict the potential for power? |
