VSS on np205 for an ls swap

(1/3) > >>

Fitzz:
So I'm pretty new to this site and did a search for a vss adapter and found some info. I'm currently doing a 5.3l swap on a 1980 Blazer with sm465 and np205. My question is "Are any of you guys familiar with the vss that speedometer world offers?" I submitted a the website and part number below. I looked at Jags that Run and Dakota Digital offerings. I like this unit because it will keep it in the cab and I won't have to run wires from the transfer case to the computer, just from the speedometer head to the computer. Any help would be appreciated.

I am not familiar with that setup...

Fitzz:
Thanks for the reply. I was hoping someone knew about it. The price seems good and I liked the fact I could still use my mechanical speedometer.

the problem i see its a 8 pulse sensor. i think you need a 40 like what dakota sells

FROM DAKOTA
igh-Frequency GM-Style Pulse Generator

The missing piece of the increasingly popular early-GM transmission swap!
With late-model GM transmissions containing an internal speed sensor outputting 128,000 Pulses Per Mile, the stock 40-tooth (40 pulse per revolution) reluctor ring provided the factory ECM with a high frequency input. The SEN-01-128 can now recreate this missing high frequency rate when converting to an older style transmission with a mechanical speedometer output.

With a standard female 7/8” thread-on fitting, the SEN-01-128 fits all GM transmissions with a mechanical speedometer cable outlet. Removable weather-tight 10’ cable provides for simple installation and cable routing. 128,000 Pulse Per Mile Sine Wave signal output is direct replacement for the stock GM internal speed sensor, allowing the ECM receive the signals it needs for proper operation.

Fits GM transmission models with 7/8” Male Threading, ie: TH350, TH400, 700r4, 2004r, etc.

i know its not what you want but i dont want you to buy the wrong thing on your original page look for the #70.

Now if you can reprogram the ecm then you might be able to use that one

according to them no one make one, im going to keep look for a little

1993-present SFI and Gen III
This sensor will allow you to run a conventional cable drive speedometer and send critical speed data to your GM PCM for proper powertrain operation.
This is a cable-pass-through style speed sensor that can be attached to the Jeep Dana and mechanical New Process transfer case outputs. It generates a usable signal required by modified GM PCM computers from 1993+ trucks to present and 1994+ cars (Vette, Camaro, Caprice), equivalent to 8,000 pulses per mile.
No known aftermarket inline sensors exist to provide the 128,000 pulse per mile (PPM) signal required by these GM PCM's. However, these PCM's can be programmed by your tuner to scale this input signal for proper operation. If you are having your GM Gen. III+ computer programmed by Novak, let us know if you are using this sensor and we'll perform this change at no extra charge.
