sweet update!

Brian has been working on getting the new Haltech ECU to work wih the progete. Completely uncharted territory.

Old Maps will not help, They do not apply.

He will have to make a new Cam Gear or Modify one to only have one magnet. That magnet has to occur 5 teeth before the Crank sensor event,

Here was the traffic back and forth.

(Edit: Apparently the E6 has a setting called "MAZDA A" which did everything for the FS engine automatically)

I am currently setting up a 1000 on a Mazda 2.0 L FS

I am running 4 Coils Direct and 4 injectors Sequential.

I have a 36 -1 Crank Position Sensor on a Magnetic
and a Magnetic Sensor on the Cam Gear that has three triggers. One by itself and two opposite and close to each other.

I understand that the setting I should use is likely 36 -1 + 1 Home but I do not understand how it will know how to trigger the injectors.

As I understand, it has to use both the fire the injectors and the coils because it's a 4 stroke. But where can I adjust for the angle of the Cam sensor, and how do I make it disregard the other magnets.

I have read and understand about the missing tooth on the crank, and understand the offset. It's brilliant. Can someone please shed some insight on how the second input is used.

Do I have to drill out the other magnets so there is only one that can be sensed by the haltech? If so is there an offset like the crank sensor from the event, or does it simply know that fuel happens 360 degrees from ignition.

I do not see a 36 -1 + 3 Home...

I am pretty technical, but I am in uncharted territory as being the only one to do this to a fully striped Protege engine..

Cam Position Magnets (3 Each)

Crank Position 36 -1

Brian,

36-1 +3 unfortunately does not exist in the ECU Manager software. You'll have to remove all but one trigger even on the camshaft if you want to setup a full sequential ignition and fuel control system. You can determine which magnet or trigger nub to retain by putting the engine at 70* Before TDC Cyl #1 compression stroke. One of the magnets or trigger nubs on the cam sprocket should be near the pickup. Retain this one, delete the others. When you setup the trigger to 36-1 + 1 cam home, it will recognize the cam sensor (home) input as it sync reference, then you simply set yout tooth offset and trigger angle so that you're ignition is occuring at correctly per your timing light and timing marks. Good luck with the project, and if you have any other questions, please don't hesitate to ask.

However,

If one of the magnets is not at the correct location, is there an Offset for just the Home?

PS.

The Home In on the Cam? and the trigger is on the Crank?
I want to get the correct words..

Can you also confirm for me that there was never a default trigger setting on the E6 called MazdaA.

My friend who is running sequential has it on that setting and has done nothing else to the car or Cam Gears.

If that is already in the Haltech Database, would it not be rather easy to reverse engineer the E6 Software and duplicate it in the new?

Hello Brian,

I have spoken to Claudio about your trigger issue. These was a setting called MazdaA in the E6X software, this was imported from a previous version of custom firmware and never doccumented. I realise this is not great, but as it hapepend 8 years ago there is not much I can do about it now.

Eric is also correct in stating that this trigger is not supported in the Platinum software.
You must modify the cam sensor if you want full sequential operation (as eric has stated by having only 1 tooth on the cam) or running half cycle operation using only the crank sensor.

the cam sensor, sync sensor, home sensor are the same thing
the trigger, ref, crank trigger are the same thing

EDIT: I referencing this PDF in the "I was reading" reference. http://www.haltech.com/downloads/accessories/S3 S4 Hall Sensor setup.pdf

I was reading that the Cam Position sensor on some older models did not have to actually be "exactly positioned" It has to occur before the Crank position sensor event so that the ECU can start the correct firing order, so it knows that Cylinder 1 is coming up.

Please consider this then...

I believe that the missing tooth on the crank 36 -1 is 67 Degrees from TDC Cyl 1.
Will the Cam Position event have to occur before that Crank Missing Tooth, or just some time before TDC Cyl 1 in order for the ECU to function.
If I can make them occur at exactly the same time, is this preferred, or is it better to have the Cam Event Occur just before/after the missing tooth Event on the Crank.

So basically what I am asking is when does the ECU have to receive the Cam Position for the 36 -1 +1Home in relationship to the Crank missing tooth.
(Before/Same/After) If I have to make a gear for this car with one magnet, might as well place it in the ideal place.


Thanks very much for your help so far, I started modding a Mazda to be the first to do stuff. I have never been disappointed and it has never been simple.

I would not have it any other way.

I will make this work with your input and then document the process to assist other Mazda Owners.

You would want the Cam signal to occur around 5 or less teeth before the missing crank teeth. This way you will have a reasonable tooth offset and the engine will start a little faster.

I think its great what you are doing - Good luck with it.

Perfect, there's the answer.

The ECU Will not care if it is not at an exact angle, but should be 5 before the Crank event.

Thanks very much. I'll post final results and what the gear looks like when it's done..

Good thing I have 3 Engines to steal parts from.

Cheers
