Basically a VSS simulator. The result is my computer thinks I'm doing a certain speed all the time but I don't get a code and no problems in 30,000 miles. The two things I found that the computer uses VSS for is 1) limits revs when you're not moving and 2) changes the idle air motor so slow the engine down if you're cruising and let the the engine idle down, otherwise rpm drops to quick and the engine dies. Thats my experience anyway.
Just another option that might help somebody

Mike, that's good info. I want to 'trick' the computer in thinking that some of the other sensors are still there so I can get rid of the CE light.
Can you give me some more info on the IC you used and do you know if it could also be used for the other sensors ?
