Ok, I wanted to post this up here because I really am in completely uncharted territory.
MAXX MAZDA, Thanks for your input... It will not matter If I ever see your settings.. They do not apply.
I 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.
[quote="BRIAN MP5T"](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..

[quote="Eric Gash"]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. Eric Gash Haltech USA Office Manager[/quote]
[quote="BRIAN MP5T"]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?[/quote]
[quote="HaltechScott"]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[/quote]
[quote="BRIAN MP5T"][color=#BFFFFF]EDIT: I referencing this PDF in the "I was reading" reference. [url]http://www.haltech.com/downloads/accessories/S3%20S4%20Hall%20Sensor%20setup.pdf[/url][/color]
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.[/quote]
[quote="HaltechScott"]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.[/quote]
[quote="BRIAN MP5T"]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[/quote]
Here is the solution.
The magnet hit 7 to 5 teeth before the Crank Missing tooth.
The new timing mark was added on the left..
I will still clean it up a bit..

I was able to verify that the timing [b]will[/b] infact be picked up by both sensors in correct order. It is looking very promising.
36-1 +Home Will allow Full Direct Fire and Sequential Injection.
I still have most of the wiring harness to install, but it is going fast.

[b]EDIT: and NOTE.[/b]
It is so cool, I had another sensor attached to the Haltech that was not attached to the car. I was able to fool it with a ferrous metal part (Ratchet Handle) to see the counter rise on the Laptop. As soon as the Haltech detects movement on the sensor it fires the fuel pump, triggers power to the coils and the injectors. If you only trigger it once, it fires the pump and shuts off, if you trigger it over and over, the pump stays on (Like it's supposed to)
It's so refreshing to see the parts work like they are supposed to.

I just hooked up the starter to verify that the Trigger and Home sensor work on the car.
If I had the Fuses in for the Coils and Injectors, it would have tried to start for real.
See Picture, Home Counter, Trigger Counter near Bottom Middle..
The 4 Home, means that the engine did 8 Revolutions or four full cycles. The 255 Triggers is divided by 8 as 31 and some decimal. Which is fine because it should be around 245 - 280 (Due to when I stopped cranking the starter)
This means that the math that the ECU is doing, is exactly the math I was expecting.
The Cam gear modification work, a Reluctor sensor has a unique property, the signal becomes stronger as speed is increased. So if this low speed test has no trouble, then it will only get better when the car is actually running.
I am still waiting on a WBO2 controller to run the engine..

This would explain why some folks have had starting problems with the E6X, and a slightly weak battery.[/QUOTE]
Yes, the faster the car turns over on the starter, the better the signal is.
The Reluctor generates a sine wave of AC current from 0.2Vac to as much as 100Vac.
[img]https://homepages.westminster.org.uk/electronics/images/sig_03.gif[/img]
As the metal blade on the 36-1 comes close, there is a Vac Peak up, and as the blade leaves, it generates an equal dip in Vac, creating on AC Current cycle or pulse. 35 full pulses per crank rotation, 70 Full pulses per full Event Cycle of 4 cylinders firing.
The faster, the better and more consistent.
Also, any deformity in the 36-1 gear will throw a spanner into the mix. If one tooth has been bent, left or right, it will create a pulse of lesser strength, it will be seen by the ECU as the missing tooth.
Ok, So I want to document something that I am working on right now..
I sent this on the Haltech Forum.
[quote="BRIAN MP5T"]Alright Tech Staff, I have another question.
In preparation to start the engine for the first time, I wanted to verify that the Trigger and Home both work and give consistent readings. The numbers worked out every time so I was happy. I then noticed that the tachometer on the IQ3 goes BANANAS. I then took a screen capture of the trace.
The White Line is the Tachometer The Green is the Fuel Pressure Red is just the TPS
Some of the other like the EGT are not connected yet so please disregard the 600 Deg EGT. The WBO2 are also not connected.
I have read that a Reluctor becomes a better stronger signal the faster it works, so Cranking the engine should be the worst case scenario. Sub 400 Rpm (Please Correct me if I have bad information)
I did some math and on a 36-1 +1 Home the number of Triggers Vs the Number of Homes looks good every time. Obviously, if the ECU is dropping teeth on the 36-1 tooth wheel, it would probably not understand...
My Main concern is, Will this RPM spike create a problem, is is Normal, is it a sign of something that is very wrong.
I have played with the filter, 0 1 2 3. it changes it a bit, but there are still spikes in the Tachometer Signal.
My next plan is to confirm that the wire is shielded all the way to the sensor.
Any information or ideas would be helpful.
[img]http://i42.tinypic.com/jkazaf.jpg[/img][/quote]
And Made some setting changes... I still believe that the Home and Trigger are working, but I can't explain the Spike in RPM.
Today I was able to get this.
[quote="BRIAN MP5T"]Teeth are not bent, Made sure the shielding was 100%
I added the Miss Counter and The Trigger between Home Counter.
The first try I got the same thing, I inverted to Falling and not rising (The opposite of how I have wired it, I checked three times) and got this which is exactly what I wanted to see. (Note: The Oil Pressure is finally rising as well which is nice to see..)
[img]http://i42.tinypic.com/5zppp5.jpg[/img]
I tried again after 1 min, and got some spikes with the same settings. Not many and they were after some cranking that would have probably started the car.
(Is it possible that a fresh and fully charged battery is just spinning the car faster and making a better signal the first time)
It's still much better and I have not gotten better results with the Filters.
Is there anything else I could try?
Thanks in advance. Once I nail this down, I'm sure the Haltech will be exactly what I need.[/quote]
Most Recent Update.
[quote="BRIAN MP5T"]So, I am still at it,[b] I think it's fixed. [/b]
I went for the overkill solution on the wiring shielding where the Haltech wire meets the stock wire.
The Haltech wire has a cable wire core and foil around. The Stock Mazda wire has a series of exposed wires that wrap around the two wires inside like a Co-Ax cable.
With some time I was able to totally isolate the center two connections in their own heatshrink. Then as ghetto as it sounds, took foil and neatly wrapped the unshielded connection from ECU wire to Sensor making sure that both ends touched the original shielding. Then with a 10" Piece of double walled heatshrink, I covered the entire thing. When heated the glue inside seals both ends.
The line is the RPM and honestly, I'm no tech, but I expect a starter cranking a motor through compression to bounce like that.. Correct me if I don't make sense..
Can you at Haltech let me know if the Trigger and Home numbers make sense for a 36-1 +Home?
