Digital Chips in cars

I have today taken the digi chips from the porcsche's in the digital set and transplanted these in a opel DTM and Merc DTM.

These work fine fitting the chip took a bit of ingenuity but their in.

One thing i have noticed is that the lights on the cars stay on and stay at a constant brightness.

Has anyone else swapped the chips to different cars
