127730 with DIS

[D Max]

Did some troubleshooting today......

This is what i all did:

checked all the connections, and they are like they should be on the wiring diagram above...
Measured the bypass wire between the the DIS and the ECM => it is not interrupted
Checked the advance with the strobo => it is 4° at idle, and goes to 12° at about 3000rpm.
It does not make a change if the bypass wire is disconnected.
(that 4° is a indication, since there was no reference point on the 3.4, and I fabricated one myself)
Swapped a ICM with an ICM I have in stock => no difference
Swapped a ECM => no difference

So the problem still exist: No tach and throws code 42
