Ah. Forgot you have an impala. I realize reducing timing when experiencing kr can help power in those areas but I just don't think we should have to run less timing than stock. I run 93 octane with...

Take away timing?!?!?! F that. Turn down for what? lol. Clean your intake valves with some top end spray (Seafoam or CRC). Mine got misfires and KR to the point of the engine going into limp mode...

I still can't find how to log MAF error in 3.x. In the old 2.x i could just create a custom pid, 114 + 116 (ltft + stft) and add that to the histograms. I can't even find histograms, only a few...

I see the graphs but my dumb ass cant figure out how to find the place to make custom PIDs so I can log MAF error (LTFT + STFT)

Also, I can't seem to find the damn histograms in versions 3.x.

I'm at work so I don't have access to the data logs but Car is knocking like a sonofabitch with even the slightest increase in ignition timing. The car hates me. I don't have a whole lot of time to...

Just read that its a known issue in 3.0 that the scanner freezes. This thing is useless in every sense of the word.
I am having trouble ironing out my cam position tables (car keeps falling on its...

for some reason I cant get my damn scanner to log for more than about 30 seconds without throwing an error and stopping. Which is preventing me from gathering any useful data and tuning the car. I...

PM sent. I don't have the car right now and probably wont for a week or so. Dumbass here didn't see a strange yet large curb/divider in a parking lot and ran into/over it. smashed the bumper, ripped...

Aw Balls. The LNF ecm I could understand. One look at the tune file on my car had me confused.

Now I'm hearing that the timing chains on the LFX tend to stretch prematurely. :banghead:

I...

Bahahaha :lol:

I looked at the stock tune file briefly and didn't see any lambda tables. Maybe I missed it. I doubt there would be a different o2 from the 10-11 LLT to the 12+ LFX. Unfortunately...

Positive thinking. The throttle plate size isn't changed. Vmax is not really ported, just the inlet honed and smoothed. Might as well burn your money.

I'm not cutting off the stock mufflers as...

I don't know what if anything the intake does for performance. Sounds really cool though. Honestly it feels like it wants to move better on the low end with the stock intake. I'm on a stock tune so...

I suppose it's possible the increased airflow from the rotofab might draw more oil through pcv.. Not sure how though.

The intake was installed last summer. Not quite on for a year. The elite catch can was the first thing i did at 700 miles. I heard good things about Elite. Don't know if it's the best but definitely...

Since one of the Elite catch cans and the clean side separator isn't doing enough, I was thinking of running two.

Anyone run two cans in-line on the dirty side?

I have to stop this oil. Ive...

Very early. like 1000 or 2000 miles. I took the can apart today and while it is catching alot of oil, much is still getting through to the intake manifold. The coalescing media was soaked in oil, the...

I regret wasting my $ on the vmax.
As some may know, my cobalt was not exactly stock lol. That being said, the camaro is still fun to drive. Rwd is fun on the wet/ snowy roads. And the manual trans...

Area, just curious, what is your reasoning for getting rid of the VMAX honed TB? Everyone swears by these things over on Camaro5 forums, although I can't see that it does a damn thing.
I'll msg you...

The top end cleaning seems to have fixed everything for now. The techs also put in some sort of fuel additive.
I wasn't getting low end kr. It was from about 2500 to 5000 rpm.
The techs advised...

I haven't written anything to the ECM. Stock tune still. Waiting to get the issues straightened out before tuning. The car has 14,500 mi. The KR wasn't just a few random spikes. it was consistent. it...

Hahah. Yes I took a step backwards on that one but desperate times called for desperate measures. The ss/sc needed an engine rebuild among many other things. More money to fix than the car was ever...

I do mostly city driving... maybe that makes a difference? I have no idea really. GM uses this engine in a LOT of cars, trucks, and utility vehicles so idk why the camaros seem to be affected worse...

After not finding any sensors, fuses, or data out of spec, I began to suspect something internal. I decided to pull the intake manifold and valve covers. Didn't need to mess with the valve covers...

Stock intake back on and reset fuel trims. Even more KR now, and I get it lower in the rpm range too. Real tired of this thing...
