The nearest I got to 'brilliant' with a P38 was to devise a method to turn off the SRS light on my early rig (in part encouraged by Storey's work with the EAS): I used software intended for - wait for it - Alpha Romeo cars of a similar vintage; Yes, I could turn the light off ... but only with the PC still connected; FAIL !!
If manufacturers could be 'persuaded' (eg, forced by law) to release electrical details of cars after (say) 20 years ther would be even more classics around: Plus we may actually Save The Planet like that rather than panicking about plastic straws up turtles' noses and other nonsense... better stop there....
