Do you need a Racepak for the ComSYNC system?
You do NOT need a Racepak for our system, the box has its own data system built right in.
Do you need a Davis Control?
No, you do not need a Davis Control. There are 4 different ways to control wheel speed.
Do you need a specific box for your combo?
There is only one box and it is tailored to your combo. Blown, nitrous, and Turbo all in one box. They are all there, whether you need them or not.
Can the software work without the box?
No box needed for the software to work. The software is designed to work without the box attached. Data can flow back and forth from the Data analyzer Graphics package to the EFI control software without the box being attached.
