Product FAQ

Where is this product assembled?

• This product is assembled in Suwanee, Georgia, USA

Is this all that I need to get started tuning my SR20DET?

• The only other potential must-have is that if your laptop doesn’t have a 9 pin serial port, you will need our USB to serial adapter to connect to this unit. However, there are several other things you may wish to add to use this unit to its full potential.
  • If you are tuning it yourself, a wideband O2 sensor system is a must have for adjusting the fuel.
  • This unit can function as a boost controller. Our boost control solenoid package is an upgrade over the stock unit.

Do I need to order a trigger wheel separately?

• The trigger wheel is included with the package.
