I'm wanting to run a custom 60-2 or 36-1 crank trigger and retain my COP for cam position on my AEM EMS 2..
Going to be using a Hall Effect sensor for pickup.

Does anyone have any insight on how to set this up in AEM? I'm slightly confused with how it will sync and how the cam vs crank sensor vs my teeth count all figure in.


thanks!

 

What Cam/Crank Sensors? Stock, T1 Trigger, AEM EPM or other type? I don't understand why your wanting 2 cam pulses for one Cycle?

 

Well I want a 36-1 crank trigger for resolution. But I have to have a way to sync cylinder 1 for tdc on compression.

Basically my question is, can I leave my epm hooked up minus the crank pickup and use a 36-1 crank pickup with a hall sensor and wire it into my crank sensor input in my aem. How will I get them to sync? And do I need a specific location for my -1 to go vs tdc on the crank?

 

Either your doing something crazy I don't understand or you've just mixup what the Teeth Count is actually doing....Which one I don't know lol:/
You have 4cylinders and 720Crank Degrees per cycle. I don't understand why you demand more than the Epm 24-1. I think the T1 Trigger is a 12-1 tooth if that makes any difference lol. I'm not aware of Tooth count having anything to do with granularity...
To get better Resolution(granularity) get your Breakpoints to where you think you'll be operating and get MicroSec/Bit set according to your Injectors.

But idk, hopefully someone else chimes in and I learn something new I had no idea about

 

Basically right now I have 1 tooth for every 30* of crank rotation. Having a 36 tooth crank trigger puts me at 1 tooth for every 10* of crank rotation, but it will also keep my accuracy greater by running it directly off the crank. I'm sure 24 teeth on the cam is enough resolution to do what I do, and so far it has been. But I attended a class this week and spoke with an engineer that is in charge of the tunning of factory engines. We went into depth about pickup resolution and the ability to have repeatability and greater control quicker with greater resolution.

So it perked my interest and would be a fairly cheap project as I would have my trigger machined and and my pickup bracket machined for my application as well.

I'm sure someone will get on here and tell me I'm wasting my time and others have made 1000+ HP with what I have, but that's obviously not the point. I'm not looking to make more power, just have a bit more accuracy using what I have.

 

I see what your saying. But, you should only have 1 cam pulse not 24..
Basically your wanting to have more updates on, engine location I assume..
I really don't think it'll give you much more Control to, get more power anywhere...

I do see what your trying to do and it comes down to if the AEM is capable of sparing the extra computing time. It could cause an oscillation kind of problem even:O

4/36=9 so your "Ign Teeth" would be something link 0-9-18-27
You would then have to changed some settings under "Cam/Crank"
Below is what I would image would be required and there maybe more. The Qmark on "MX Sync Test" I would image needs to be 36 as well(I'm not sure what that option does)

I don't know what the 1000hp guys are doing. I just give info as I understand it and hope it helps.
