Ignition Setup Guide
Setting up your ignition system can be a daunting task. Not all of us are familiar with how it works , let alone setting up a custom system.  This guide should help any Haltech E-series owners with getting your engine up and running correctly if you are a little unsure of what some features do , or if you just want to know why they are there.  This page is not of any use to you if you do not run a Haltech , or if you are running a fuel only system. It may however make it easier for you to understand what is involved in upgrading to ignition control.


Haltech Ignition Setup Page
The Haltech Ignition Setup Page can be accessed by hitting the  <CTRL-G> keys with the E6K model , or by hitting <ALT-S> to bring up the Setup pull-down menu and selecting Ignition Setup with older models, while either Online or Offline.  Some features will not be availble unless you are Online though. For the purpose of using this guide , it would be a good idea to switch the system over to Advanced Mode for the time being. This is done by going to the Main Setup Page by hitting <CTRL-M> and changing the System Mode to Advanced    The HITman always recommends saving your current setup to a file before modifying any setup features just incase you need to go back to where it was.
 

E6A / E6S Models
Trigger Angle - BTDC (45 - 100)
The trigger angle is the number of degrees the ECU will wait from the trigger event to actually outputing a signal to fire the ignition coil. Varying this value has the same effect as moving the distributor or crank angle sensor. Increasing the value retards the timing , decreasing the value advances the timing. This setting is used to ZERO the timing.

Timing Lock (On , Off)
The Timing Lock is used to ZERO the ignition timing before the engine is used. Without doing this the ignition timing values that are read on the ECU will be different to that which is actually happening at the crankshaft. What we need to know now is what the marks on the crankshaft stand for. For example , on most engines there is a TDC (Top Dead Centre) mark and usually a mark at the idle timing point of around 10 degrees BTDC. When you switch the Timing Lock to ON it locks the timing on the ECU to 10 degrees BTDC. Now what you need to do is go and line up at the crankshaft using a timing light , the 10 degree mark with the pointer. You can do this by either adjusting the Trigger Angle , or by moving the distributor or crank angle sensor base.For rotary engines they have two marks, and neither of them are TDC. The Yellow Mark is for 5 degrees ATDC and the Orange Mark is for 20 degrees ATDC. Notice they are ATDC and not BTDC. The Haltech ECU when set to Rotary Mode and with the Timing Lock set to ON will lock the timing at -5 degrees so you can line up the Yellow Mark with the pointer while having a timing light connected to the front - lower spark plug lead ( Lead plug - Rotor 1). Once the timing is zeroed correctly then you can switch the Timing Lock back to OFF.

Trigger Edge (Rising , Falling)
The trigger edge is best found by experimentation or by consulting a professional Haltech Dealer.

Trigger Type (Standard , Multitooth , Twin Trigger , Motronic)
The Trigger Type is the style of ignition pickup you are using. If you are using a pickup with one trigger per cylinder then you would use the Standard type. If you have more ignition pickup teeth than you have cylinders then most likely you will use the Multitooth setting. Twin Trigger systems are not very common , but if you think you have this setup then contact a Haltech Dealer.

Number of Teeth (10 - 255)
Pretty self explained here. How many teeth are on the trigger device.

Tooth Offset (0 - 255)
This is how many teeth after receiving a home trigger the ECU should count before calculating the ignition timing. Changing this value will require you to re-ZERO the timing again. The value is found through experimentation.

Spark Mode (Distributor , Direct Fire , Twin Distributor)
If you are running a distributor then this should be set to Distributor Mode. If you are running a waste-spark or single-coil-per-plug setup this should be set to Direct Fire. For Twin Distributors you know what to do here. If you are running a rotary engine and you are using the Mazda OEM ignition setup for Direct Fire, this setting should be switched to Distributor Mode.

Coils on 4 Cyl Motor (2 , 4)
Only available when running in 4-cylinder , piston , direct fire mode. If you are running waste-spark with two dual-post coils you will set this value to 2. If you are not running waste-spark and have an individual coil per plug then set this to 4.

Engine Type (Piston , Rotary)
Easy enough with this one. Are you running a Piston engine or a Rotary Engine.

Output Type (Constant Duty , Constant Charge)
This setting is where you tell the ECU what type of ignitor module you are running. Constant Duty ignitors can do there own coil charge time whereas Constant Charge ignitor modules require the ECU to control the Coil Charge Time. If in doubt contact a Haltech Dealer.

Coil Charge Time (mS) (0.0 - 8.2)
This is the charge time of the coil in milliseconds. Only available if the Output Type is set to Constant Charge. Typically you can start from 3.5ms as a safe point , but to be sure you should contact a Haltech Dealer if you do not know the correct value. Having it wrong by a large amount can damage the coils or ignitors.

The Output Edge is (Falling , Rising)
This should be set to Falling for almost all applications , unless otherwise specified.
 
 

E6K Model
The E6K computers have slighty different ignition setup features due to the onboard software adjustable reluctor adaptor. Otherwise it has the same basic adjustments.

Trigger Input (Hall Effect , Int. Reluctor)
This adjustment tells the ECU whether you are using a Hall Effect type digital trigger , or a magnetic reluctor type trigger. When using the Hall Effect setting below it will appear the Trigger Edge adjustment. When using the Int. Reluctor setting below it will appear the Trigger Gain adjustment.

Home Input (Hall Effect , Internal Reluctor)
The Home Input will not appear if the Trigger Type is set to Motronic. Otherwise it is adjusted as per the Trigger Input above but it is for the Home Trigger and not the Main Trigger.

Trigger Edge (Rising , Falling)
Appears when in the Hall Effect mode. Same adjustment as for the E6A / E6S above.

Home Edge (Rising , Falling)
Appears when in the Hall Effect mode. Same adjustment as for the E6A / E6S above.

Trigger Gain (0 - 7)
The Trigger Gain controls the sensitivity of the internal reluctor adaptor on the Main Trigger Input , which is used for magnetic pickups. The optimum value is found through experimentation.

Home Gain (0 - 7)
Same as Trigger Gain , but for the Home trigger Input

Trigger Angle - BTDC (45 - 100)
Same as above for E6A / E6S

Timing Lock (On - Off)
Same as for E6A / E6S , but now when turned to ON a new adjustment appears allowig to you alter the Timing Lock value in degrees BTDC.

Trigger Type (Standard , Twin Distributor , Motronic , Multitooth , Nissan , Subaru)
Same as for E6A / E6S but now with support for the Nissan 360 tooth cam sensor , and Subaru odd-number pickup.

The rest of the adjustment are as per the E6A / E6S
