this is a cheat sheet i have laminated and carry on my sled.
this is the sheet that Boston Racing has on his web site. i just removed some stuff i didnt need and added a few things for quick reference. if i find some numbers that work better at different air temperatures and elevations i jot them down on my paper for my next ride.
GREEN MODE: Default setting Light 4 (bigger number lower AF ratio)14-15 AFR
The green mode on the control box controls all of your cruising fuel adjustment. The lower the light the less fuel it will add. The higher the light the more fuel it will add. A safe AFR for this light setting is 14-15. Keep in mind that the AFR will just around a lot in this mode due to light loading of the track, and throttle positioning.
Yellow Mode: Default setting Light 4
The yellow mode is a De Accelerator pump. This mode is activated by quick throttle movements. This keeps the sled from bogging on throttle stabs. Lowering the light will pull more fuel, while raising the light will add more fuel during light activation.
RED Mode: Default setting Light 4 (bigger number lower AF)12.5 AFR
The Red mode is your WOT fuel adjustment. The box will display Red light while it’s activated. Lower the light will add less fuel, raising the light will add more fuel. The mode is best to fine tune your AFR at WOT. Shoot for 12.5 on the AFR gauge.
Green Blue Mode: Default setting Light 4.5 (bigger number lower AF)12.5 AFR
The Green blue mode is your Amount of fuel per PSI of boost. While riding your sled this mode is active any time the Blue LED is displaying on light number 8. This mode is best to dial in your WOT AFR. Than fine tune it with your red mode. For example say Green blue mode adds 10% fuel per light setting. And the red mode adds 1% of fuel per light setting. So during at WOT pull if your AFR was 13, you would want to raise the light to get a richer condition, which will lower your AFR reading. Target AFR is 12.5while Green blue mode is active.
YellowBlue Mode: Default setting light 2 (lower light more sensitive)
The yellow blue mode works in conjunction with the solid yellow mode. This mode determines how when to turn on the solid yellow mode. Its controls the rate of throttle movement to turn on the yellow lights. Lowering the light will make it more sensitive to throttle movement. Raising the light will make it less sensitive to throttle movements.. While riding the sled you want the adjust this mode so you can stab the throttle from a complete dead stop without the sled bogging. However you don’t want to make it to sensitive that you activate it to easily causing it to turn on during cruising and fluctuating the throttle slightly. Keep in mind this mode works directly with the Sold Yellow mode. Yellow mode controls the amount of fuel, and yellow blue controls the rate that it activates. Light setting of 2 is normal for elevations above 6000ft. Light setting 4 is normal for elevations of 1500-4500ft.
Red Blue Mode: Default setting light 4.5 (lower number kicks on red sooner)
Red Blue mode is the RPM activation mode for the solid red light. Lowering this light will turn the Red mode on at a lower RPM, Raising the light will turn the Red mode on at a higher RPM. This mode disables yellow mode and yellow blue mode. It’s important to not lower this light setting to much or you may experience a bog during on and off throttle activity. This is because when the red mode turns on it shuts your fuel pull mode off. Adjust this mode so you can go from WOT to nothing back to WOT without any bogging or activating the DET light. The default setting is 4.5.
