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.

/ 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
