Can anyone tell me what the frequency range is for the VSS from 0-100?

I just bought the Jaycar frequency switch to solve my full throttle lean out when taking off. I plan on making it go from open to closed loop after roughly 50km/h to stop the Impco gear from trying to stall the engine everytime I get heavy on the pedal. Once the speed drops below 30km/h, it will revert back to open loop.

THe kit requires that a frequency range be selected, hence the question.

The inputs into the speedo indicator are:
104.167Hz - - - - > 60Kph
173.61Hz- - - - - > 100Kph
190.97Hz- - - - - > 110Kph
260.4Hz- - - - - - > 150Kph

You should be able to figure out the relationships below 60Kph.

Finished the mod, calibrated it with a*** end of car on jackstands. Got it running great, with switch on occuring at 50km/h, and switch off at 40km/h. You can notice a huge difference in power at take-off, because the mixer is adjusted slightly richer by default, and the solenoid is what adjusts it leaner to compensate.

So no backfires at startup due to the richer mixture, more take-off power with no hesitation or lean-out, and super economy over 50km/h!

Test drove it and i'm very happy with the result.

Next step, since the relay is DPDT, is to connect the extra pole to the TCC. Bring on the savings!!! :)
