TCU TurboLamik

Hi, I am currently intsalling the tcu on a 1jz with stock ecu on e46. I have tried connecting the speed output to the engine ecu but it seems to not work as the check engine light comes up after 80km/h. i have tried connecting a 10k ohm pull up resistor to the circuit with the speed output pin being ground but it seems to also not work.

TCU has pull up and pull down inside. Just activate them if needed.

I don't fully understand why you're doing this, better write to us on Viber +48 502 726 105
