Delteq with LM1 Wideband rpm help

I have tried LM1's recommendation from their manuals to get rpm to work using the LM1, rpm cable and inductive clamp. RPMS are all over the place.
Who here has actually got this cocktail of crap to work for you to get AFR and RPMs together.
And please, no get rid of the DELTEQ options

SOLVED: Delteq with LM1 Wideband rpm help

Update:
The inductive clamp doesnt not work due to saturation/waste spark type coils.
So, I finally tapped off the Delteq module to get an RPM signal from the tach output coming from the ignition module. Then you auto config the rpm converter cable at the 2000rpm till it picks up proper timing.
So all in all, persistence pays off.
