Plug Gap for BKR7E-11 @ 13-15psi?
I currently have them gapped at .039 on my 1.6 with MSPNP. I am experiencing the misfire issue as discussed in other threads. Is the gap too high? Are there going to be any adverse effects from lowering the gap down? Nobody really elaborated on the plug gaps other than that you want to run as big of a gap as you can without blowing out boost. I am also looking into adding additional grounds to the ecu, but in the meantime was wondering if I should change the gap on my plugs.
Thanks in advance for your answers.

I don't think you're going to be able to run larger than .030 gap, probably more like .025
I'm going to open the gap on mine up to .050 and see what happens. No issues to almost 18 psi at .045

I'd run as suggested by those that have it working for them. .020 sounds super small to me (ie: easy to foul the plugs), but if its working... can't argue with that.

Yea it does kinda foul plugs, but then again I'm running two heat range cooler plugs when 99% of the time I'm not spraying nitrous. If I were turbo and hit boost everyday, they would probably stay cleaner. But it does run fine so no complaints yet. Besides, I'm not trying to get 50K miles out of my plugs, they get changed every couple months anyway.
FWIW, it had a BAD misifire at .035 on the bottle. I gapped to .025 and that helped a ton, probably fixed it. I just run .020 anyway so I don't have to worry about a misfire, as it can cause a lot of damage on a nitrous motor and rob lots of HP.

Uhm. Ran additional grounding. That's cryptic?
LOL, sorry for being facetious. One of the guys at DIY soldered in a jumper lead from the main ground pad and broke it out to extra pins in the center connector. Ran 3 leads from the center connector the the head. Also cleaned up the 2 factory grounding points at the head.
Car runs like a freakin champ.

Thats why I was wondering, because I asked Atlanta93LE and he said that:
"I opened the ECU and added a jumper from the ground pin to an open pin on my extension harness, and ran that from the harness to the engine grounding point. I run a MSPNP 9093; the later cars had more grounds from the factory."
So I am wondering if someone has posted instructions how to do this, because I am not one to play around with PCB's and soldering.

Let me rephrase that. I wouldnt feel comfortable going in a soldering things unless I had a good picture diagram showing specifically what needs to be done. I am not one to "f" with stuff that I am not sure about. If no one has them, I will send mine in to DIYautotune.
