I've thought about this every time I have have a CIS issue. In theory it sounds great, but the more I read about it, it sounds like a PITA. While I'm not a fan of CIS troubleshooting, I dont think I would like setting up a fuel curve or ignition advance curve with the laptop either. If you can get a map setup for your car it should be a lot easier. Otherwise, I've read some horror stories.
