AEM ECU Problem

[vtecnology]

Hello. Since I install the AEM ECU the speedometer stop working.

I swap ECU for the OEM one and works fine.

I check everything in the ECU option and nothing.

Any one in the same situation before?

I call AEM and they don't know what can be the problem.

I try to check the voltage coming out the speed sensor and is good,the ground is good and wen I plug the Computer shows the speed in the screen.

Is simple not working in the instrument panel.
