Haltec Setup. 4age. Trigger/Injection/Fuel.

[Bugzbarney]

Hi everyone,

Need some help with Haltec Setup on my 4age AE82.
Specifically a Haltec Sprint 500, as thats what im running.

In regard to trigger, fuel and ignition.
Firstly im having trouble selecting trigger type, the drop down menu dosent give me the configuration i have (bigport dizzy, 3 wire 24tooth + 4) without setting this up im getting nowhere fast. Suggestions?

Injection mode gives me 4 options:
- Sequential
- Semi sequential
- Batch
-Multipoint,

Reading here i understand my dizzy cant run sequential but im not sure whether to choose batch or multi point (whats the difference?).

Im assuming trigger edge is falling and sensor type is reluctor.

Any feedback would be highly appreciated,
Cheers
Bugz

i think (but not sure) batch fire is more a V engine thing firing one whole bank at a time, but multi point would be more grouped in 2's?
still unsure what one setup you would use as it could be ether being a 4 cylinder.

if i could i would see what my 3tc haltech is set on.

bugz: yes, without a home signal you can't run sequential. If you feel brave you could remove 3 of teeth off the 4-tooth wheel and then you could (plus you could then run waste-spark or sequential spark) - but you'd then have to work out where in the timing cycle that remaining tooth is.

bugz - if you dont want to do as "thechuckster" suggested, then grab a 4AGZE crank angle sensor and use it! Will be apples!

PM me if you need a hand with the haltech.

Hey man.

Im running a haltech E6A on my 4age, I'm also using a dizzy ignition setup so I imagine our configurations will be very similar.

Fuel Injection
I use 'multipoint'. As I understand it, this means all injectors fire at the same time. Its not quite as efficient as batch fire or sequential but its more simple for the electronics to drive (as it only needs a single 'driver' from the ECU for all four injectors). I think this is the way the factory injectors are driven anyway. Another way to tell your best configuration is the injector harness. If all injector plugs are on the one channel than you have multipoint. I'd have a close look at the sprint 500 manual to see which setup is best for you with what you have. Haltech documentation is pretty comprehensive from my experience.

Trigger Setup and Ignition
Like fuel injection, there are a few main approaches to sparking/ignition. These are distributor based ignition or direct fire. Distributor based ignition only has one coil that provides spark to all plugs, whereas direct fire has more than one coil, usually one coil per spark plug. The bottom line is that if you want to go direct fire (and have multiple ignition coils) then your trigger setup gets more complicated and needs a 'home' trigger to tell the ECU which coil to fire first (because order becomes important as there is no longer a distributor 'distributing' a generic spark event to the correct plug).

A 'trigger' event refers to a spark event, so every time the ecu receives a trigger signal, it needs to produce a spark. I'm not quite sure how to build a trigger setup for toothed wheel CAS because I'm using a hall effect sensor with wheel with magnets. If there is an option to just change out your CAS with a 4agze CAS and your haltech can natively support it, then I would definately go with that option. The problem I had was my haltech is so old that it can't read the 4age and 4agze cam angle sensors, so i had no choice but to custom make a trigger sensor system.

PM me also if you want a hand.

P.S.

If you can select 'reluctor' in your ignition setup for your haltech then that is a very good sign. It may be that you don't even need to use the 4agze CAS. I'm not sure of the ze CAS, but I know the factory 4age CAS is a 'magnetic reluctor'. Id check the manual, but if I were you I'd give it a shot with the factory 4age CAS first.

This is what i would do:
1. Set fuel injection to multipoint
2. Set ignition/trigger to 'reluctor' and keep factory 4age CAS (use haltech wiring diagram to ensure its actually wired into the trigger input)
3. Lock timing to 10 degree BTDC (it should be an option in the haltech setup)
4. Remove fuel pump fuse and spark plugs
5. Turn car over using start motorer only, and hold a timing gun on the crank.
6. Rotate CAS until you get timing on 10 deg BTDC (this is to ensure that the haltech ignition timing is calibrated with the engine, ie so what it thinks is 10 degrees is actually 10 degrees )
7. While cranking easily (without spark plugs and fuel) check RPM output on haltech to ensure it looks 'right'. If its all over the place your fucked. If its 400-800 and consistent, your in business.
8. Put everything back on and try to fire it up
9. Once running, unlock ignition timing and set it to whatever you want.
10. Dance.

also note, rpm will jump all over the place and cause problems higher in the rev range (above idle rpms a bit) if the reluctor is wired incorrectly (reverse polarity).

it will appear good and then turn to shit later on in the rev range.

Easiest way is to ditch your ae82 distributor and grab an ae92 one. They only have a one tooth wheel instead of the 4 tooth wheel you currently have. This pdf will help as well, its Motec but it should give you a place to start. http://www.motec.com.au/filedownload...pdf?docid=1280

Sorry i havent replied sooner guys. I ended up doing exactly what thechuckster suggested. I shaved off 3 of the 4 teeth, hence making my setup a 24-1 rather than 24-4.

A thing to note if doing this is really make sure the teeth are gone, i originally didnt shave mine low enough, ended up taking more off too ensure nothing was being picked up.
Further more to this, my electrics within my dizzy were stuffed and the dizzy was wired incorrectly, with the home and trigger being read by the haltech wrong.


With this things sorted, she all runs sweet now.

Now its Multitooth 24-1.
Trigger Angle 70 degrees
Sequestion fuel setup.


If any wants some suggestions or whatever, feel free to ask.

Thanks all,
Bugz
