Case Studies

Every build here runs an OEM ZF 8HP with its factory transmission software untouched — no reflash, no donor car — behind engines ZF never intended, from an LS3 V8 to a turbocharged Mercedes four, on standalone ECUs. IOcan sits in the middle and recreates the network the gearbox expects.

If you're planning a swap around an 8HP, these are the wiring, calibration and results: a P1 rally finish at altitude, and 15,000 km of European road driving.
