Never one to rest on his laurels, Modifry has come up with yet another ingenious mod for the S2000: The Yellow Jacket Speedometer Calibrator. This module has been specifically designed for the S2000 and allows you to compensate for an erroneously high speedometer/odometer reading.

Using the Yellow Jacket, you can compensate for installing high-performance (numerically higher) differential gears or correct erroneously high factory speedometer readings. (many S2000 owners report speedometer errors between 2% and 6% higher than actual)

There are numerous benefits to using a Yellow Jacket over the competing units on the market:

Tiny size - less than 1" x 2" x 1/2" (smallest product on the market that we know of)

Simple rotary dials make adjustment easy (unlike products with confusing dip switches).

Low power consumption ~ 10ma (less than half of other products)

Absolutely no added speedometer lag

Operates at all speeds (unlike some products that don't work at low speeds)

Real time calibration (unlike other devices that require a power cycle). No need to pull over and shut the car off between each adjustment like other products require.

Note: This device cannot be used to compensate for erroneously low speedometer readings. It ONLY adjusts the speedometer to read lower than it does now. If your speedometer currently reads too low, this product will not adjust it higher.


The S2K International Marketplace is proud to be the vendor of choice for all of Modifry's fine products, this one included.

We have a few units in stock now with more units in production so we don't anticipate any large delay due to early demand. For more information on the Yellow Jacket and to place your order, please follow this link: http://www.gofastlab.com/s2ki/customer/pro...44&cat=0&page=1
