Ok I'm kind of at a loss here. Wouldn't colder plugs cause the car to run more rich? I put in some hotter plugs (BPR7ES) and my AFR's are way rich now. I'm not sure if this is because of hot weather or what..

I'll elaborate more when I get home.. My gf's keyboard feels like a 1920's typewriter and the spacebar barely works

 

Plugs don't affect your AFR. When you say you put in hotter plugs (BPR7ES), does this mean you had aftermarket COLDER plugs in before (BPR8ES)? BPR7ES are equivalent to stock...same heat range.

 

Yes exactly.. I was running the colder plugs now I'm back to stock heat range. The car feels really smooth now but I was running around 11.1AFR and now I'm down to 10.8.

It could be weather tho.. It's been getting real damn hot then cooling down.

Would plug gap have any effect on the AFR?

I realize these are stupid questions but I'll never know if I don't ask

 

do you have a flash or AFC ?????

 

I have the mail in dynoflash and SAFC-II. Right now my safc settings a just like -1 and -2. I think my main problem is the only time I log is at night.. It's fairy cool but humid.. then daytime is hot & humid.

 

plug doesn't effect the afr, it might effect how efficient the air/fuel mixture ignites.

temperature does effect boost, coolant temp, air volume, etc... which could cause your afr to run a little richer or little lean.

your gf probably spilled some coke on her keyboard.

 

Yeah, if you have both the flash and S-AFC II, then you're all set. Doesn't the II have 2 maps? You should do some tuning in the heat, then do some at night and have 2 maps to run. Since I have an S-AFC I, I have to make adjustments quite often as the temp changes so that my AFR is optimum.

 

i have a flash and i am running very rich..... in the 10's....im not useing my AFC untill i find out what is wrong....i replaced my sparkplugs 2 weeks ago and checked them last night and they where black as hell....my old ones with 19,000 miles looked better then the ones that where 2 weeks old..

 

What do you mean "until you find out what is wrong"? Most people's flashes have them running in the 10s for AFR. That's why you then fine-tune with the S-AFC to get it in the low-to-mid 11s. Do you think it's more than just the flash?

300+whp running that rich is pretty impressive w/o cams.

 

Provens dyno i put down 303 A/F's 11.3......my local dyno 260whp A/Fs in the 10's...both are dynojet dynos...know one understands this

 

Ah, ok, that answered both of my questions. You need to get a logger or find someone with a logger to verify this discrepancy. You don't know if one or the other dyno is off...or if you have developed a problem since leaving Pruven.

 

i'm thinking about getting on of these http://www.auterraweb.com/index.html or going to turbotrix and haveing them find out what is wrong...... i would like a wideband but think this could help me out more.... and/or Trubotrix can check my flash and A/Fs on there dyno

 

Here is a lil shot of my AFR after some work.. I'm running 100 octane and 22psi right now Car is insane!
