An interesting prospect...thanks for making me aware, I will have a look and let y'all know!

Kelu that is great news on your tune with the new turbo.
Looking forward to see a video at the track and the news you broke the 12 sec 1/4 time.
Good luck

Next race will be in mid Sept, I will keep you posted as usual

Kelu drifted this topic himself!

Can't wait to see him so I can push him in the river.

After some logging few weird moments have been encountered.

Switched heat range 8 spark plugs with the standard heat range 6 - NGK 6509 (thank you elff) because in low rpms and low load it made some weird fuel corrections because of not proper burning with so cold plugs.

Also removed the evaporative valve from intake manifold because it was making some weird corrections at idle, normally when you log for MAF calibration you have to unplug that sensor so it won't interfere by pouring gases into the intake and ruin the calibration.

Kelu, if you get a chance, see if your EVAP solenoid is bad. I have been trying to keep track of the failures at what pressures and for how long to see if there is any correlation, also have a possible fix for the failures.

Thanks,
Dave

Kelu

FYI
The NGK 6509 are 1 step colder than the AC Delco 41-108s
So you do have room to go up one more heat range

Some weeks ago before last turbo change, I got some errors regarding the EVAP solenoid, I didn't care back than.
From the last week 20 mins logs I noticed once, at a stop light when idling, it was correcting the fuel a lot even I was close to a good point of the calibration, it was correcting with 20% on average.

Talked with the ECU tuner and he told me he saw that too while was calibrating the MAF on the dyno once at idle.

I don't care about EVAP, it can blow outside, I just don't want to drop all the garbage in my engine because of some stupid emission limitations. I asked mechanic to eliminate whole that part.

Next is cam case vent tubes, I will vent them into air because now I have the MAF on cold side pipe and I shouldn't care about recirculate them, right?

I wish
Right now I have 2 of the very Non Ultra versions.

tazz · « **Reply #286 on:** July 23, 2012, 01:23:59 PM »

I thought the NGK 6509's are gasket seal and not taper seal? Will those fit the LNF?

elff · « **Reply #287 on:** July 23, 2012, 03:03:59 PM »

If they didn't Kelu's car would not be working

tazz · « **Reply #288 on:** July 23, 2012, 05:31:40 PM »

So they are taper seal.
I was wanting to try the IX series but could not find one that was a taper seal.
Thanks

elff · « **Reply #289 on:** July 23, 2012, 06:08:02 PM »

Personally, my car hated them. I gave them to Kelu because mine runs better on the AC Delco 41-108s

tazz · « **Reply #290 on:** July 23, 2012, 06:18:27 PM »

MY car likes the colder plugs that originally came with the vehicle so I was wanting to try the 6509's.

Gentleman Jack · « **Reply #291 on:** July 23, 2012, 06:30:59 PM »

Interesting. My car thinks spark plugs are for sissies

Diesel or death!!!!!!!!!!

Oh. Damn.

Kelu · « **Reply #292 on:** July 23, 2012, 06:54:07 PM »

I tried both 6509 and 3787, both work, can't say which ones are better because I tested them in different setups.

Tomorrow I will check the EVAP solenoid

Back on post 96. I switch to Autolite XP5263, equivalent to the AC 41-102. The original plug for the early 07 GXP. Been running them over 17k. with no problems. IIRC the only difference is the Autolite as a .6mm tip & the AC has a .4mm tip

SKY888 · « **Reply #294 on:** July 24, 2012, 05:57:19 AM »

Kelu, with my old set-up (gt35).....it really liked the AC-Delco 41-108 at .0028 gap

and I'll prolly try 6509 on my new set-up.

40rtyp · « **Reply #295 on:** July 24, 2012, 06:44:11 AM »

Oh man, from my experience autolites are hot garbage. My car under acceleration on those plugs @.0028 would blow out all the time. I then re-gaped to .0032 and it still didn't help. I got the NGK IV off amazon for $40 and it was Night and Day. They are gaped @.0032. I have since had no signs of the plugs failing and its been a solid 6 months. The stocker(Denso) are actually damn good plugs as well and hmmmmm.....NGK makes them, how bout them apples. The autolites I will never use again. I think they are fine if you haven't modified your Sky, other than that....you have been warned.

Are you sure you can just let it blow outside without causing problems?

miller11386 · « **Reply #297 on:** July 24, 2012, 07:40:24 AM »

I would assume if you disable the P0443 you would never know the difference.... but I havent tried it.

kennysabarese · « **Reply #298 on:** July 24, 2012, 08:07:42 AM »

I think it would be important to understand how the entire ventilation system works for EVAP and the crankcase so you don't disable half of it. I'm sure there's documentation on how to do it properly somewhere for ecotec.

miller11386 · « **Reply #299 on:** July 24, 2012, 08:45:04 AM »

are you talking about the crank case evacuation or the purge from the fuel tank?

The crank case vent is solved by a catch can...

The gas evap is a line from the tank to the intake manifold to evacuate pressures in the gas tank. This has nothing to do with the crank case ventilation. I would think if you just tie the solenoid somewhere/ put a filter on the line from the gas tank you should not have any issues. other than the P0443... It just needs a way to vent to atmosphere so it doesn't 'splode in the hot sun. However I will agree that our querky ECM may find a way to get disgruntled about not seeing the fuel vapors from the gas tank....

I know all the other high HP cars have not seen an issue from this... so I bet Kelu's solenoid is probably malfunctioning. Mine died at ~60k miles
