I installed and wired the sensor to my factory VSS pin and moved the factory VSS pin to the Spare Speed Input on my AEM Series 1. However, after much reating of older posts, I can't quite figure out the calibration for the Xenocron VSS without taking it on the street and getting a ticket. Also, how would I go about setting up the Factory VSS as a Spare Speed Input in the AEM?

 

What size tire are you using?

As for the spare speed input, will depend on the ECU/engine being used. If you can clarify these three things, I can get you the information you are looking for.

 

Tires are M&H 24x3.6x15. Engine is a LS/Vtec run by an old AEM Series 1. I can get it to somewhat read a signal but the resolution is pretty bad. The signal also seems to drop out at higher speeds.

JDM Inc, I have read a lot on this, but somehow missed this article. I am pretty sure this is how I had it set up, but will have to check. It seems that we got it pretty close, but would lose the reading in the ecu past 45 mph. I ran this in the ecu as the primary VSS and tried to run the stock VSS signal in as the secondary VSS in the AEM, but that didn't work. Setting the sensor up with the recommended air gap resulted in poor resolution and no reading. Increasing the air gap helped, but still lost input at higher revolutions.
