8HP control

MaxxECU now supports the 8HP 45/70/90 (GEN1) gearbox. More gearboxes in the GEN1 series, like the 8HP55 (AWD), are being investigated and will probably be available later on as a free update.
To control the GEN1 8HP gearbox, a custom MaxxECU TCU firmware needs to be reflashed using an external tool.
Selected features
  • Convert and control any GEN1 ZF 8HP 45/70/90 gearbox.
  • Controls the stock TCU, no internal wiring or soldering needed.
  • Controllable shiftpoints from 1500 to 9000rpm
  • Transbrake available in both M and D, first or second gear up to 7000rpm.

  • Dodge, BMW shifter or use the shift emulation feature with keypad or custom shifter.
  • A Kickdown feature is available for superfast downshifts.
