You guys think that ignition coils off honda odyssay are the same as honda civic's.
I used odyssay's ignition coils (the same looking coils as civic's) I got them free.
I did the whole conversion ove the weekend, the car started fine with no problems, but when driving and hitting boost over 12psi the engine just missfires. I used to ran 25psi all day long on stock coils. The question is if the coils off v6 motor are weeker than the 4 cilinder once. It looks to me that probably the spark is not strong enough.

scroll down I did find this. Does it seem like a manufacturer uses the same coil design for varying applications? Looks like 2.4ms is standard..

Hello guys!!! I post a my graphic comparisson of my car. Blue line was with the stock OEM plugs en red line was with the the coil cops made by me 
!!!
The logs was in the same road, same gas, maybe with a degreess temp less but in the same conditions.
Coils are Denso from a Civic 2010.
One more thing! Right now I run my car with more timing advance, that happen after install the new coils
Ichage AFR too, because with new coils the AFR was richer than before.
BTW, in my logs I put a weight that is not from my car but the road where I made the logs have an inclination, for that I put that weight. And yes, I run 205/60/R16 in my Evo, the original tires from Japan!!
