Where is this product assembled?

  • This product is assembled in Gainesville, Georgia, USA

Is this all that I need to get started tuning my 944?

  • 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.

Will I need to make any changes to the trigger wheel setup to run a distributorless ignition?

  • The stock crank trigger can support distributorless ignition without any changes.
