This is great, I am going to use this info on my N/A build

 

I was going to ask about the benefits. Here is my answer.
I'm going to do this next check.
Thanks again for the info and write up.

 

I know about the Spoolinup kit, but a few folks in this thread have complained about pricing.

 

I have a set of tsx coils for sale /shameless plug

definitely very easy to wire in cop on the evo

 

if you make some pretty ones I'll buy them

 

good write up,
but i dont see the point in it. yes you are running COP, but its still wasted spark (firing 2+3 at the same time and 1+4) and because its still wasted spark it wont make any difference to anything logically. You are still firing 2 coils at any time. Potentially this could be worse actually because the honda coils are made to fire 1 time every 2 turns of the crank, but now theyre each firing at DOUBLE their standard rate (due to wasted spark). Also, the ECU is controlling coil dwell right? How do you know these coils suit the dwell that the stock coils run?

Never understood how COP can make evos "run better" or "make more power" etc. Unless the stock coils are pathetic.

I dont see the point in it unless you run an aftermarket ECU and run proper sequential ignition and adjust coil dwell correctly so you dont burn out the coils in 10k kms.....

Here is the original write up that the pictures were stolen from. Give credit where credit is due.

Yes it is correct, I'm very clear in my thread and this was what I said at the beginning ""This is a topic I saw on another forum and found it very interesting: ""

I just wanted to share what I had found.

 

nice this is very help full to everyone but he should make a video and do it step by step so everyone can try it and have a better picture of it .. but still nice

 

no matter that the coils work twice, this does not mean that they only work for 10k miles, maybe you're right, if an evo rpm cut is 8k is like an honda S2000 cut to 16k rpm, the coil function is to raise the voltage in a split second and release it. If the life of one coil is 20 years at normal speed discharge, this means that if forced to go twice discharges, this coil perhaps die in 10 years, or if the life of a coil is 200k miles, at the twice the speed, this maybe die in 100k miles. I can live with that.

 

you didnt get everything i said did you?

They will run double the number of spark discharges, but also you dont know if the dwell time is too high or too low. Too high and you get premature wear and too low and you get a crap spark. Why change when you technically get the worst of all worlds? Either go standalone or nothing IMO. These reviews of COP being a whole world better and giving 20horses just sounds retarded to me. Maybe i should try it so i can see the light...............

 

Don't knock it until you try it. You might like it.

 

lol..........................but the lack of logic

 

try it, you'll love it.

 

I ran one and back to back with the original coil packs and it made a massive improvement. Also i removed the OE earth line from the wiring harness and made one to earth on the engine black, so it was much shorter and larger Don't know if it helps, but in the end the OE coil packs earths next to the thermostat housing, almost a metre of wire :s
