1 : Which information from the Ecumaster unit does your unit need?
2 : Does your unit need the actual speed of the vehicle?
3 : What is the most optimal operating temperature for 8HP? Do you have this information from 8HP to CAN and then to Ecumaster?
4 : Can I install only an oil cooler without thermostat and exchanger if I heat the transmission by spinning the wheels on a jack ?
The vehicle is for drift racing
Sorry for the English and thanks for the advice :-)

Hello
1-If you have Emu installed then TCU needs TPS RPM and Mapsensor. The TCU receives this information from the can bus
2- 8hp has a built-in speed sensor and is able to send vehicle speed over Can to EMU
3- oil temp 40C-90C
4- for sports, I recommend an air cooler, not a heat exchanger, it can be without a thermostat

Thank you very much for your reply . Let's get to work :-)
One more question : Is it possible to program one of the TCU outputs to switch the fan to the oil cooler at 80 degrees for example ?
I assume your TCU knows the oil temperature and can send in CAN to Ecumaster?

By default, AUX 1 is set as the fan relay control signal. By default, the output activates when the gearbox oil temperature reaches 85 degrees
