Next delay-
Currently my reluctor and crank sensor are set on the (edit 5th) tooth as my VR sensor worked fine on that tooth with my EDIS.
So Holley has a couple different recommendations for which tooth the Hall Effect sensor should be on.
1- If you divide the 36 tooth reluctor by 10 then you get 3.6 which if I understand it correctly then you follow these instructions off the Holley Tech forum page. See below.
2- There are pages that show the sensor should be mounted on the 7th tooth of the reluctor. Two ways of attaining this. Fordboy rotated the ring on his HB to align the sensor on the 7th tooth. Other way is to make a bracket so the sensor can be rotated down from the stock Explorer location (3 teeth farther).
Another way that isn't feasible is to use the Holley stuff for a Mustang but it won't fit on the Exploder HB. It spaces the pulley (V-belt) out 3/8" of an inch which for me with all custom brackets and tight clearance for my custom accessory mounts doesn't work either.
Missing tooth crank trigger:
The TDC Tooth Number (amount of teeth after missing teeth) is the Ignition Reference Angle.
On a
36-1 trigger wheel, each tooth equates to 10 degrees. 36 x 10° = 360°.
The Ignition Reference Angle needs to be at least 10° higher than the maximum amount of timing used.
7 teeth is 70° of Ignition Reference Angle, which allows you up to 60° of timing advance (in the Base Timing Table).
6 teeth is 60° of Ignition Reference Angle, which allows you up to 50° of timing advance (in the Base Timing Table).
I'm adding this as I set my Hall Effect sensor on the 5th tooth so I am set up as below:
5 teeth is 50° of Ignition Reference Angle, which allows you up to 40° of timing advance (in the Base Timing Table).
On a
60-2 trigger wheel, each tooth equates to 6 degrees. 60 x 6° = 360°.
The Ignition Reference Angle needs to be at least 10° higher than the maximum amount of timing used.
12 teeth is 72° of Ignition Reference Angle, which allows you up to 62° of timing advance (in the Base Timing Table).
11 teeth is 66° of Ignition Reference Angle, which allows you up to 56° of timing advance (in the Base Timing Table).
10 teeth is 60° of Ignition Reference Angle, which allows you up to 50° of timing advance (in the Base Timing Table).
9 teeth is 54° of Ignition Reference Angle, which allows you up to 44° of timing advance (in the Base Timing Table).
It gets confusing because for a missing tooth type crank trigger, the EFI software uses the term "TDC Tooth Number" to describe the
Ignition Reference Angle. Which is fine, since the amount of teeth (after the missing teeth) is more a definitive method to identify it.

UPDATE: The new V4+ EFI software allows the Ignition Reference Angle to be changed from −360° to +360° BTDC on # 1.
cylinder. This also eliminates the requirement to alter the Firing Order in Ignition Parameters for some unusual applications.

Crank Sensor, Hall Effect wiring with 558-431 harness
Using the Mouser # GS100502 Hall Effect sensor for the crank the wiring is:
As per Holley "
A – Red – 8V to 20V clean switched power. If connecting directly to the ECU, ECU pin B20 (“EST 12V Output”) on Holley EFI systems would be a good choice. Pin E at the “Ignition” connector of Holley P/N 558-431 or 558-306 can be used for these harnesses.
B – White – Sensor Output to ECU crank signal (ECU pin A30 on Holley EFI). Pin A at the “Ignition” connector of Holley P/N 558-431 or 558-306 can be used for these harnesses.
C – Black – Sensor ground. Connect to a “clean” ECU ground, such as ECU pin A14 (“IPU Ground”) on Holley EFI systems. Pin C at the “Ignition” connector of Holley P/N 558-431 or 558-306 can be used for these harnesses. " as per Holley
As per Mouse website:
Mouse ZF 100502 Hall Effect is what I'm using.
Below is the wiring for it:
Brown wire is - 12v switched power
Black wire is - Output V
Blue wire is - Ground
The Cam Sensor wiring as per Holley for a '96-97 Pigtail is as follows:
Dk Blue/Orange = Cam signal to ECU
Blk/White = Ground
Red = + 12V pwr
I am using WeatherPack connectors on the crank sensor end of the 558-431 harness to eliminate the need for buying special crimping pliers and pins/connectors for the only one Holley Metri pack. plug I have lots of WeatherPack stuff.
