This J3 Chip and Programmer pack gives you the ability to do your own custom tuning. Included in the pack is a T.I. Performance J3 chip along with a USB based J3 Programmer, and all cables required to start tuning. Using this pack will give you control of fuel, spark, idle, limiters and many other parameters within the ECU!
Using this pack will require some knowledge of tuning – have a good read of the tuning resources in our Library before purchasing. A Wideband O2 Controller is essential to monitor your changes – we sell the Techedge 2J Wideband O2 Controller.
Use the drop down if you would like us to create you a Custom Tune as a base to get you started. See Stage 1 / 2 Custom Tune and Stage 3 Custom Tune for more information about which tune type is required for your setup.
