Description

Using our 4l80e swap harness (link) and need 4l80e tuning? We can help. Our harness requires basic changes in HP tuners, but we will also want to edit your shift points to accommodate the 4L80e’s different gearing. You can choose to either send in your own module(s) (please include ECM if applicable as well even though changes are not made to it), or purchase a core outright*. Our TCMs are not locked, in case you wish to modify it further. This tuning only works with the PCM of NC plug and play 4l80e harness. Changes include for our 4l80e tuning include:

  • Necessary changes for PCM of NC Harness (no segment swaps)
  • Full shift pattern update (upshifts/downshifts/WOT)
  • Adjustment for torque converter if necessary
  • Scaling back/deletion of torque management

 

*Cores are only available for T42 transmission controllers.
