Much confused.
After a lot of reading about the GM ECU, seems it does use speed info to help control the idle speed and throttle positioning (so says GM).
Anyway, I'm currently using the Dakota Digital to send the ECU a speed signal (it works, however mechanical is recommended). There is a school of thought that a mechanical pulse generator (ring and magnetic sensor) is more responsive to speed, hence the ECU is more responsive in what it does.
Questions;
1. Does the number of teeth on the ring make a difference, if so how many are needed by the LS3?
2. Does the ECU differentiate between a speed signal from an axle sensor versus a wheel sensor if no ABS is present?
3. Does it mater where the ring is set up (target is the rear axle)?
4. Has anyone set up a mechanical system to the ECU (like to read your blog)?
5. Will the Graz speed sensor work for the GM ECU (I presume not, since its never been discussed that I am aware of)?
6. What's a good source for a ring and what senor should be used?
