Yeah, mine runs great, but has a nasty drivetrain vibration I can't isolate. But the engine part does exactly what it's supposed to do, and does it well... :)
I assume you could feed the ECU the signal, but to what end? It isn't the ECU causing the problem, it's something upstream. If you suspect a bad ECU, I'd just swap one out... Make sure you test at the fuel pump relay (pin 31b) for the tach signal, as well as at the tach itself. Maybe you've got a shorted wire somewhere...
On my '80, since it has really primative CIS, I spliced in a connection at the tachometer to get the signal over to the LH ECU. This worked well and was a snap to set up. If you get a good signal over there (pin 10 on the instrument cluster) just make your own connection... :)
