Just found this article right here on Gearhead-efi. Working my way thru 18 pages...

Think I will need to come up with a VSS for my conversion to work properly.

cheers

i believe you need a 2000 PPM signal for VSS input on the 747. You can get an inline unit that hooks up to your speedometer cable. This is probably the easiest. OEM got this signal a few different ways over the years, optical sensor on the back of speedo with a "VSS buffer" (usually a small green plastic box), and in later years a 40 tooth reluctor wheel that would be fed into a DRAC/VSSB. Both systems can take the signal and make 2000 PPM (ecu), 4000 ppm (cruise control), etc. you should not have to worry about these though.

EDIT: i am in the lower mainland btw, have a chip burner and emulator.

Good to meet another BC boy, thanks for the info. I have a really nice burner from the 90's, EPROM eraser, and just found out about the emulator...I may have to buy one, would make tuning so much easier.

PS I have one of those inline speedo cable VSS things, it's a Ford product but probably works the same, it's 2 wires. I'll have to check it out, would sure be nice if it could drive the ECM directly.
