7060 VSS Questions

[seads505]

OK folks, here's the background info: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?1367-7747-ANTY-Help-the-new-guy!

I'm looking to take advantage of the speed-related advantages (although small) of fuel cut, lean cruise, etc. that the 7060 has to offer.

So I am running the 7060 PCM and have a couple of VSS-related questions:

Has anyone developed a BIN which allows the input VSS pulses to be adjusted? See pic: http://i116.photobucket.com/albums/o33/StanIROCZ/Jerico/VSS/PromChangesforVSS.jpg
If not, does anyone have a recommendation on adding a 40 pulse per minute setup (Hall/VR sensor) to my truck? I've browsed around Jags That Run website, but I don't see an option for a differential-mounted toothed wheel setup for a 14 bolt rear end...just a reminder, my 700R4 is NOT the 4L60E, it's original off of the 86 GMC, so I'm not sure I can add a relucter ring without doing some (semi)major modifications to the tranny.


Keep in mind, I have the 2-pulse optical buffer behind the cluster, so my though is if I can adjust the vss ppm in TunerStudio then theoretically I can just use that for my speed signal.

Thoughts?

That is the concept I'm referring to, but it would need to be for a GM 14 bolt yoke (not sure if the one in the pic is the same)...http://www.billavista.com/Tech/Articles/14-Bolt_1410_Yoke_Kit/images/DCP_9329.jpg

I have CNC access and could have one made, so I'd need dimensions and/or CAD drawings for the wheel...unless someone sells the wheel and mounting bracket as a kit. I guess the bracket wouldn't be too difficult to fab up.

Any input on adjusting the ppm in TunerPro? Updated BINs?

I don't have access to a GM 14 bolt rear end. I can do the CAD, I would need the yoke measurements.

I can't help on adjusting the ppm in TunerPro.
