I am hoping someone might know how many Pulses per Mile the 6L80E REPLICATED TOS SIGNAL Pin 16 is?

Maybe 4000 / 8000 / 16000?

Thanks in advance,

Are the posted instructions for the AEM 30-4110?

The AEM 30-4110 is Plug-n-Play with the '7427 WBO2 setup, no calibrations / no adjustments are required.

What engine are you planning to put a turbo on?

Installing a chip that has been programmed with the edits is required.:thumbsup:

I think using a ‘7730 / ‘7727 V6 Memcal is a good plan.

I think a 4K VSS is a very poor option because the Speed Pulse Per Rev number will be extremely low. The 8K VSS already has a low Speed Pulse Per Rev number and is likely the lowest cost option too.

Chip code BBNT is for a 1993 4.3 CPI, definition $E6

I used a budget friendly Digital Dakota 8K VSS. The Speed Pulse Per Rev will be very ODD with the 8K VSS

It appears to me that the starter solenoid sends a voltage to the computer that the engine is being started cranking.

The fuel pump relay actually has 3 high side connectors, that allow for Normally Closed contacts and Normally Open contacts.

The fuel pump power is connected by the Normally Opened contacts.

The fuel pump relay wiring described above seems odd to me.

Typically, the fuel pump wiring high side gets battery+ from a wire with an inline fusible link or a fuse that eventually is connected...

It appears the connector pictured is for an ATC fuse, see link below. Pink wire with a Black stripe is typically ignition "ON". Not sure what the tan/white wire is for.

The ECM needs to know when the fuel pump is "On" / "Fuel Pump Signal" The wiring for the "Fuel Pump Signal" is spliced into the power wire going to the fuel pump.

The Fuel Pump Relay and / or Oil Pressure Switch will supply power to the fuel pump. The oil pressure switch is a backup to the fuel pump relay should the fuel pump relay fail. I did an experiment...

The Memcal functions:
Limp Home Mode

When possible, using an original Memcal for a specific engine / transmission configuration is a good plan. The...

Would I be correct the netress is a network of resistors used limp home fueling?

Would I be correct cylinder select sets up injector firing sequence?

Awesome to learn the netress is the same.

Would I be correct that the external ESC uses the 100k knock sensor? Possibly Standard Motor Products KS7?
