REVO SPS1 ($100) &amp; SPS3 ($175)

I used this on my S4, but recently went stage 3, so I no longer have a need for these and they're up for grabs.

PM me if you're interested and would like to see pictures of the actual units.

See details below:

All Revo performance software programs are switchable via the OBD2 port on your car using our SPS device. Simply plug in, select a program, wait a few seconds, remove the SPS and start the car.

SPS1 (retail $199)
This version of the Serial Port Switch (SPS 1) allows the user the ability to switch between different levels of performance via the diagnostic port. The user simply selects the program on the SPS, plugs it into the diagnostic port for a few seconds until an audible bleep indicates the program is loaded, and then removes the SPS.

SPS2 (retail $269)
This version expands upon the functionality of the SPS1 by offering multiple performance programmes that are octane specific, along with the added feature of the security program. The security feature effectively leaves the car inoperable until the SPS2 is reinserted and appropriately set. The car will not start even if the thief has the key. There are no wires or "boxes" that are easily defeated and the car will not start even if the ECU is replaced.

SPS3 (retail $349)
This version utilises the same features as the SPS1 and SPS2 with the added benefit of having variable boost and timing control. This functionality allows the user to adjust the car to varying degrees of performance by changing the boost pressures from the turbo. It also allows the user to use any grade of fuel at any time without the worry of damage to the engine. It also can be adjusted to take full advantage of race fuel or octane boosters that are typically out of the range of any performance.
