wanted to see how my car is runnin so pulled out spark plugs and checked em.. what do they look like to u.. i need a second opinion.. im guessin its on the little lean side.. also how come #1 and #2 are gapped at .35 and #3 and #4 are at .30 ?? my tuner gapped them..

btw im turbocharged LS. bone stock runnin 6 psi Daily driven.. maybe they look kind of lean because lately ive just been cruising? not really hitting WOT so that made it look lean for plugs?



heres pic of my dyno tune if helps u by seein air/fuel.

 

thats wierd that the gaps are difffrent. but it def appear to be running slightly lean...nothing thats a major promblem

also when i get new plugs. should i gap them all the same? also what kind should i buy for my setup?

Engine:
• JDM B18B from HMotors: ( very reputable shop )
compression 200+ across the board. less then 25k miles. came from JAPAN so less then 25k miles and it came from automatic so it wasnt beat up ( it had an automatic flywheel ). and also thats why my dyno #'s turned out to be so good.

since we are on the subject, and i don't wanna create another thread about the same thing.. what does mine look like?

lean or rich?

 

^ urs look rich to me. they are alot darker then mines..

 

Bump. Anyone can give me a second reassurance that these arnt "too Lean" or diff gapping on diff plugs matter?

 

bahaha, we all use the same plugs!

you should mark what # cylinder goes with what plug, yours looks a little on the rich side and the other guys looks to be normal for the most part

I would go back and get another print out of your a/f ratio.

Ask for it to only plot the curve between 13.5:1 and 10:1. The way the curve is compressed makes it seem a lot more smooth than it actually is (I'm betting this was done on purpose by the tuner).

I'll try to clarify, though I'm not sure which part you didn't understand. For starters, I didn't mention the word "lean" at all.

Go back to place where you dynoed your car and ask them to print out your dyno chart again.

Currently your a/f chart shows the curve between 18:1 and 10:1. Your curve never goes above 13.5:1, so there's absolutely no reason to plot the chart any higher than that. Also, by only plotting between 13.5:1 and 10:1 you will be able to actually see what your a/f ratio is.

I can barely make out anything on your a/f chart, because it's so compressed.

 

You need closer pics of the electrodes in order to tell for sure. The plugs look awfully rich from a distance, especially in that picture.

As you can see by the burn marks on the insulator, those plugs are the wrong heat range. Step them up at least one heat range before you start melting stuff.

oic. i kinda understand... it slike streching a grap and using the wrong window mode sort of.. u actually dont really see the precious #'s cause its soo compressed.. cause the scales x and y axies are too large right?

No, just the y-values.

You need to use colder range plugs when you turbocharge. It looks like you will need a heat range 7 plug. BKR7E is typically the plug of choice.

Iridium is alright, but overly expensive. The little tip of iridium has been known to break off inside the motor causing severe damage. I haven't seen it, so run what you want, but I prefer copper plugs.

 

BKR7E ? allrights ill go find those and use those

 

I get mine on http://www.clubplug.net. They are NGK BKR7ES-11.
