SO ive been doing tons of reading, Researching the pros and cons of COP.
Now the only question i really have is. Whats the most cost effective way to convert my bseries to COP, with out using the s300 or the aem twinfire. I currently am open minded to ANY EMS im thinking AEM EMS 4 or infinity.

 

aem with epm and k series coils. ill even sell you my setup. 750hp no problems at all

 

There are a ton of great EMS available that have enough ignition outputs to handle what you're looking to do.

Haltech PS1000, MoTec M84, AEM Series 2, ProEFI 48 are all great entry level systems with the ability to do plenty for the average hobbyist.

The Infinity looks promising, but until it's been out for a bit, has undergone it's tweaks and revisions, and has some legitimate feedback, I'd keep it as a distant option for now.

 

That too is my main concern, it looks great (infinity) but it is an AEM product so after it has gone through its paces on other peoples car. I wont be dropping cash on it.

 

Ditto this...also comes down to who is tuning your vehicle and what their experience and opinion is. If you are tuning yourself...the choice is solely up to you.

 

i ran aemv1 with k series coils and t1 trigger and loved it. picked up 100hp over a msd dis and coil setup and ran so much better with large inj. this being said, to me there is no con to going cop. there are used parts always forsale that you can pick up cheap to run cop. im not a big fan of the aem emp tho, have put it on a couple cars and always have had problems with them. always end up going with the cam trigger kit

 

Yup...forgot to add that. The EMS you choose will only be beneficial to you if the person tuning it is familiar and competent with the system.

T1 Trigger for sure. It's simple, cost-effective, and reliable.

There was just a car in here that had both an EPM and Trigger physically on it, long story short the EPM stopped working so the trigger went on lol.

 

SO one way to get rid of the distributor or the EPM is to use the T1 Trigger?

Now the T1 Trigger will not work with the Oem honda Ecu, But it will however work on a standalone such as AEM?

 

Correct me if I'm wrong, but the AEM EMS needs a "hall mod" to run the trigger correct? But I am assembling a full AEM kit, and will run the trigger myself for the first time. Also needing input on the subject.

 

Some of the very first AEM needed modification because they only had 3 coil drivers.
All I had to do was change the jumper location inside my ecu. Here is the write up I did for mine.

From what I understand the Honda P28 can be slightly converted to use coils.

 

Nope, the Honda ecu has but one ignition output. Without an additional piece of hardware and some codes changes it won't work

 

All the new aems have the proper amount of coil outputs and no modification other than to the tune is needed.

It all depends on what you want to support what power goals. From what I hear there are people using stock k20 coils up to 900hp without problems, no cdi box.

If you want a cdi box just make sure to get a good one like the m&w, either way much better than distributor and wires and so on.

Your cheapest bet would be to go aem, k20 coils and run 3 extra wires into the harness for the 3 extra triggers, one will come from the stock ignition signal wire thats on the factory harness. Thats the easiest way to go.

 

The honda ECU does have a table for coil dwell, It's mislabeled in crome as base timing, but it's a dwell adder. Neptune has dwell control.

so could you not use that and make a controller?

 

Ems, t1 trigger and k20 coils with the 4130 plate here and works great.
D17 coils can fit under the stock plug cover as well.
Cbr coils are good and can be had cheap with a harness you would need a msd dis-4 or equivalent.

Simplest way imho is the ems, t1 setup and k20 coils and dont look back

 

I apologize but 4150?

 

its the shops name that makes the coil on plug adapter plates. 4130fab

 

yes 4130fab thats who made the plate.

 

If you are going to go with a dumb coil and a CDI, the DIS-4 should be a last resort, lol. Unless you need it for the 2-step, which I can only see happening if you're using a K-Pro or an EMS with shitty 2-step/burnout limit functions.

M&W Pro14 for a street/strip car, Drag4/Pro Drag4 for anything dedicated.

K.I.S.S. concept - a new OEM K-Coil can do ~250 per hole, they're cheap and they work.

 

So I have ems already, to run cop on over 800whp(hopefully) all that is needed is a t1 trigger kit, and a set of k20 coils? I always thought it was much more complicated!

 

^ That why I started this tread.

I'm stuck on going with a EMS , T1 trigger and, either d17, k20, j series or, CBR.
I wont need a CDI, Twin Fire, or M&W Pro14 for a street/strip car, Drag4/Pro Drag4.

I just wish there was a way to do it with s300

Few questions though.
what is a CDI?
Whats the K.I.S.S concept?
whats the benefit of going with or with out an ignition box with COP in stead of going to the ECU and no Ignition box?

I want to Completely remove the factory distributor, then replace it with a cam seal.

 

Thats it!

a1320addict makes a nice little k-coil subharness as well to make it even easier (power, ground and the 4 triggers to your EMS)

 

There is a way with s300 but you have to keep the dis for the pickup. But for the price of the hondata cop kit you could sell the s300 and buy a used aem,trigger and coils for less then s300 and the cop kit from hondata. And you would have a much more reliable ign system then with hondata still using the stock dis for a pickup.

 

 

Using the cam pickup, wouldn't you still need a TDC sensor?
