I've been reading up on this site about VSS and how it supposedly made idle and tuning much easier for some... Is it really a noticable difference at idle? Mine currently wants to stumble and die when coming to a stop, (not everytime but often) amoung other issues that i just need to get tuned. I'm currently using the 8747 ECM. (I know slow and ancient but i'm not after peak power just good and smooth running for my 4 wheel toy)
With the VSS, how do i know how many PPM's i need to make up for 4.10 gears and 37" tall tires? From what i can tell i need a cable to electric VSS, that will wire directly into the ECM, and still have the cable? By the way this is on a TBI converted '85 K5 Blazer with a 700R4. Feel free to point me to a link that i've overlooked that explains all this...
