Can anyone give me some insight on on the yellow box. I believe I need one now, and wanted to know if I could make my own or if anyone had experience with these and could give me some insight on how to go about this the best way.

thanks!

 

The speedometers and odometer on the S2000, and nearly all other modern cars, are calibrated from the factory with a plus 1-2 percent error. This means that actual speed or recorded mileage is actually lower than that indicated on the speedometer and odometer.

This 1-2 percent error can be magnified even further when you install aftermarket wheels and tires or change the rear gear set. For example, the 4.44 rear gear set for the S2000, introduces another plus 7-8 percent error. This error can result in speeding tickets and other moving violations, put your car out of warranty prematurely, mislead you into premature maintenance expense, and other problems.

The Yellow Box corrects speedometer and odometer error to within 1/10 of a mile or MPH. The Yellow Box is installed in the vehicle and corrects the speedo signal in real-time. It can be re-adjusted at any time to correct for changes in gearing and wheel sizes. Installation and calibration are easy, within the skill of most back-yard mechanics. If installed properly, the Yellow Box will not induce tampering messages from the vehicle's ECU.

 

I have 4.44 gears in my ride and i'm currently using the Modifry Yellow Jacket to account for the speedo error. Very easy to use and install if you're good at following directions. Here's the link:

Actually...the error can probably save you tickets because the speedo reads high (positive error). You'd be going slower than what you're actually reading...so if you think you're going 80mph on the freeway...you're actually going about 74mph

 

Nice thanks for the info!

 

nick hows your 4.44 gears? did you pick up the one from huy?

 

No i bought brand new ones from High End. Gears are great

I already had alot more midband gain from the reflash...the gears just make it that much more driveable

 

where did you get the reflash?

 

autowave inc in orange county. GREAT shop...would recommend them to anyone.

 

price to reflash?
