Zenon HID lights - Has anyone installed HID's without problems?

[Phobius]

I recently had Zenon H.I.D head light bulbs installed, the first thing I noticed is that it didn't start the way it used to. It would run for a second and stall out. The next time it would run properly. So I took off on it and the next problem I experienced is after hard starting it wouldn't go into gear. After much sweating , cursing, and cajoling, I got it into gear and drove straight home. I put the original Halogen lamps back in, problem solved.
So here is what I would love feedback on, is there a way to put in a circuit to fool the computer into thinking it has the Halogens in while actually having the Zenon bulbs in? Has anyone successfully installed a set of HID lamps without problems.
