eCtune

what type of plugs do u guys use in ur high HP cars. Resistor or Non Resistor plugs. i made a post about this on honda-tech cause i was having some serious issues with ignition breakup. What do you eCtune guys use and have u had any problems like this? here's the thread: http://www.honda-tech.com/zerothread/2200860 (BTW the car was running crome, not eCtune............ i should make the switch right? )

u should switch yes. Drop me a mail maybe we can work something out

is the problem due to the software design? why would one program act weird and another one run just fine? Can u shed any light on that calvin? the car i was talking about wasnt my car, it was my friends car. Im building my car this year calvin, and i'll be running eCtune in it. i will def. hit u up once im done.

Everyone around here seems to use the part # 4554. Those worked really well in my car and others in this forum.

the 4554 are non resistor type. how much power have u made on these plugs and with what EMS?

everyone around here that i know runs the ngk BKR7E-11 w/o any issues. its what i have in my car right now. i do have some ngk 4554's on order in time for the dyno...if i get my ostrich figured out.

Go 11 threads down from this one and all your answers are there. "Big Power Figures & Spark Plugs"

i would just point to that topic thank you

i read that entire post. but i still didnt see a definite answer ro resistor vs non-resistor plugs. it looks like everyone is using non-resistor plugs with good results including me too, but with one EMS and not the other.... which is strange to me. i think burgemass said that NGK iridiums (resistor type) are know for the tips falling off into the motor for high HP setups. thats pretty scarier.... makes me wanna stay with the plugs i've been using all along

I have used the 4554 on eCtune and Crome, Have only had issues on 1 car and it ended up being the wires. Also If your timing is too retarded it will cause break up, so it could be a timing issue between programs. (from what I can tell all of them are a little different, with the exception of Crome which is a LOT different when you start going up high in boost.) Long story short, 4554 FTW!

im gonna stick with the non-resistor plugs. i've been read n up on some horror stories of the tips of iridiums breaking off and falling into the motor causing damage. Thanks for all the help!

Thats why we are here

At our shop we use the NGK BKR7E plugs on most mild under 400hp setups On my 400+ hp setup I bought the NGK # 7173 R5672A-8's Just thought I'd add that to the mix dk

When it comes to the thousands of volts used in today's HE ignitions, a little less usually won't make much difference. In this case, I think ohm's law says it will reduce the voltage a little. Given than the whole ignition circuit has tons of fairly high resistance items in it (ferrous/graphite core wires, graphite rotor top contact, etc), its not the worst thing in the world. I've always found that ignitions don't so much make power, rather they prevent the loss of power. Doubling the coil voltage on a car that's breaking up (so that it doesn't break up) will obviously make power, but doubling it again won't magicly make the gas mixture more explosive or give it a faster burn speed. Well-controlled ignition > brute-force powerful ignition

a lot of people use #4554 NON-Projected type what is the real difference between projected and non-projected when tuning and the effect on the setup?
