MED9.1 SEAT LEON TFSI 185

by **maximus1980** » Tue Nov 27, 2012 11:42 pm

Hi i wonder if anyone can help with my seat leon with k04 conversion, i had a stage 2+ file made for me but doesn't seem that good as boost spikes all over the rev range.

The a2l/damos that is available to download isn't much use as the map addresses don't seem to match my ecu.

Can anyone help locate the addresses.

Thanks in advance

Gasoline turbo engines are the most difficult to tune, There are a lot of things that can go wrong if you do not what are you doing, This engines can NOT sustain bad remaps like diesel engines can.

MED9 is very complex ECU. All the calculations are based on engine torque and engine load. There are NO classic boost maps like in diesel car.

Tuning MED9 needs a lot of knowledge. Tuning MED9 with upgraded engine parts is very difficult if the tuner dose not have the car to test the maps writen in the ECU.

Hi RPM freak

Can u help with the map locations?. I have found 3/4 of the map addresses but not all that's why i ask for help on the forum.

I had a tuned file made but just need to make some adjustments.

Thanks

Post the file and the map pack so we can see what maps are problematic.

Do you recommand source of information (books, webstie, etc )can help us to understand the MED9.1 ECU or the right way to tune it.
