with flash on...


Like i said, they dont look to bad to me, so i dont know why im having alot of hiccuping on partial throttle every once in a while and why im missing up top on ful throttle, but i can boost just fine on partial throttle. Hmmm....

Oh, you can see a huge pic, just copy the url into the address bar, it will take away teh resize...

they are fine.

Thats weird as hell, i figured one of my injectors was stuck open or something, causing me to run really rich, and teh ecu going into closed loop and running like crap. Hmmm, wonder what i could be then...

Re:What do you think of my Spark plugs? *PICS*
 

Rich at cruise for sure.
Damn those are tall plugs, are they like heat range 4 or something lol

Your on BBKA's map right? His did the same thing, like it didnt wanna run in closed loop, and just stayed in openloop. I know Pat has been making changes to his map since he got a WB. Maybe he'll post it here.

Well, there stock d16z6 plugs, whats the part number for the colder plugs??

Plug reading does you no good unless you do it right...

To get a good reading of your combustion chamber events you must first- Go wide open throttle (WOT) for several seconds, about 4-5 seconds all out. Then, let off, allow the revs to drop and shut the car off. Remove your plugs (recommended after engine is below 100oF.) Dark to light Tan= Good combustion. I forgot exactly what other colors mean, I may look it back up and post. Probably not.

This is the way we read spark plugs after dyno pulls. WOT, then shut it down and let it cool for a few minutes, take reading per cylinder, fix problem.

White is to lean, Black is to rich. Coffee cream light brownn is the color to look for

ZFR6J-11 i just got mine!

Re:What do you think of my Spark plugs? *PICS*
 

I'm not going to argue this post. I can tell you the way us hot rod guys do it. Called a high rev shut down. You hate to do it, but you just bring that bitch up in the rpm range then kill the key switch. There was something else it was called, another name used by hot rod guys.. can't recall. Anyways that is our method.

The gaps on the plugs look massive to me!

What are they gapped to?

Re:What do you think of my Spark plugs? *PICS*
 

One thing about normal plug reading, I'd hate to just suddenly cut the oil flow to the turbo after a WOT pull...

Re:What do you think of my Spark plugs? *PICS*
 

Yeah, but most of the guys doing this are high output N/A motors. The thing will run for a few more seconds, so it's not like you're going to sieze it right then and there.

Not to mention there won't be that much boost in the turbo while in neutral, not like you have the load of 3rd gear behind you.

Re:What do you think of my Spark plugs? *PICS*
 

A WOT pull is useless without load, and it's unlikely that you'll coke the bearings at once but I don't think it's good practice to do this repeatively on an oilcooled turbo.

yah check that out.
