I pulled my plugs for the first time since i had the car tuned. Do these look good? Sorry for the quality i was using my blackberry camera.

 

a little on the lean side but ok

 

Really? I thought they were alittle rich?

 

they look fine cuz your doing more pt driving then wot driving so there going to look lean cuz if it tuned right the a/f will be around 13.7-15.0

 

try using Macro on your camera, it helps alot.

 

Timing looks ok too. Could be advanced a bit more, but not too bad.

 

hard to tell from the picture but it looks like the timing is a little too advanced being that the color change looks to be below the apex of the ground strap. Just hard to see anything from the pictures. Not only that, but if the engine was shut off at idle and then you pulled the plugs, its only going to show the ignition timing result from idle on the ground strap. Trying to determine the timing on the ground strap at WOT in 10lbs of boost from idle is a little too risky for me.

with better pictures, you will get better answers.

 

The blacker the plug the richer when the tip is white its lean yours seem ok just open any haynes manual and go to last page all the info is in there

 

just because the exposed portion is white, do not mean it is too lean. But its not white and you can see a portion of the fuel ring.

 

Thats why I said a little lean! Get a uego in that to get some true readings a must if your boosting or running juice

 

are those 6's , how far many threads down on the plug is the color change (6's are usually a stage too hot )

 

^^ Those look like BKR8E. Look like 8s here.

 

They are BKR6E-11

I was told these plugs are one step colder by NGK.

These are what the car was tuned on.

 

two of those plugs looks like the heat range goes down 4 threads.

 

What should i do? Should i get the correct one step colder plug? Will it effect my tune?

 

well telling us your setup would help. 6's are stock for b-series and 5's are stock on d-series. so if you are running 200whp on a d-series you might be ok with the 6's.

also if you want insight on how the car is performing in boost you will need to make a WOT pull, shut the car down at high rpm then pull the plugs for a reading. do you have a wideband? that will tell you what you need to know about afr. is the car tuned? who tuned it? can you post a map? i just feel like there are easier way of monitoring your car than reading plugs.

bump

 

Put new plugs in it. Do a WOT 2nd/3rd gear pull and at the top shut the car off. Pull the plugs and read them / take pics.

 

What plugs should i be using? If i put a different plug in will it effect the tune?

 

I run the bkr7e on my boost d16.

 

What plugs should i do the WOT/shut off test with?

How do my fuel/ign tables look?

 

dont go into boost at low rpms.

 

haha I hope he can't hit those cells.

 

What? Please explain? Are you telling me the tune is bad?
