I think my turbo is blowing out my spark, I have a much upgraded Fuel System.
When the Car is at normal temperature, And start to get into boost mode,4-5000 RPM. my car seems to "misfire", it will make like a TATATTAT sound. Like a machine gun. I am using OEM NGK plugs with an unmodified Plug Gap. MSD 6A box along with a Blaster 2 coil.
Any Info or Suggestions????
Thanks.

hey whats up d16turbo. i can help u on this get ngk bkre7. they are one step colder and gap them to 0.30 and your spark wont blow out

 

Oh ****, I thought that name looked familiar. Thanks for the info, right now I am reading : https://honda-tech.com/zerothread?id=510127

 

yw, gapping is key

 

So is it just "BKR7E" or is their another number ofter that??
Yep, i will try the gap at .30 or .35.

 

but what version is it. this pic came up at advance auto parts under BKR7E AKA NGK-6097.

Tatattat scares me. Are you sure it didn't sound like pingehpingping?

 

HA.
Are you being sarcastic or are you representing the sound of detonation
Hey, ah, honda9369 are BKR7E-11 The V-Spark or Standard. I head V-Spark Is an over kill for turbos?

 

Never Mind, I just figures out the answer: BKR7E-11, is VSPARK; BKR7E(S)-11 is Standard. So many spark plug type, should I get the BKR7E-11 or the BKR7ES-11

 

BKR7E-11 sorry i was spacin out v-power

 

I've been experiencing the sme problem for some reason just recently. Get into boost and the car seems to lose power and seems to misfire. I threw a P1123 code (short-term fuel correction too low) and went to like 10:1 AFR.

I will try going to a colder plug, but with only 50% more power than stock I don't think I need it?

 

Well since you say get the VPOWER, which is BKR7E-11... Those come as .44 gap. SO the question is are the VPOWER gaps adjustable just like the normal ones. im trying go get a .38 gap or so.

 

I adjusted mine just fine, closing it to 0.030.

 

Ok cool, you adjusted yours to .30, is that with the NGK V Power.
Hows that going.

 

Well, I rechecked the plugs, spark plug wire continuity, and my wiring for the S-AFCII and the MSD DIS-2, and it didn't fix it. Turns out, I simply miscalculated the low-throttle fuel correction with the AFC. My stock injectors are 15# and I am using 19#, so I figured I would need (15/19-1)*100 or -21% correction.

But this didn't work, and my ECU (an OBDII) was maxing out the short-term fuel correction to try to make the engine run stoich. This is what caused the trouble code and the misfiring.

After a couple test runs I found that -10% across the low-throttle correction worked fine. I am still using -15% for the high-thottle, though. (With the OBDII I am unable to really tune the low-throttle, but it doesn't matter since boost comes at high throttle anyway, and the ECU can correct for several pounds of boost when cruising. I don't know why so many Honda guys switch to OBDI) The car runs like a champ again.

 

well I'm glad you got that short term fuel stuff worked out. That is alot of **** to know. that is why I don't what to get an Apexi Unit; But I will need one eventually.
