I was looking at a page over at diy-efi, "1227730 Basic Tuning and Features Q&A". And Q#11 caught my eye:
Q: How do I tell the ECM I have a magnetic VSS instead of a optical VSS?
Change bit 6 of the value at location $8018 to zero.
Is this seriously all there is to it? I believe I have an optical VSS in my Trooper's speedometer which I thought was 4000ppm, but it isn't working with my current ECU. I figured that was because it's an optical square wave instead of magnetic sine wave. When I switch over to the 1227727, will I be able to CHOOSE one or the other? That would be great!
