No, it should have been almost an hour. Now that I look at it I'm wondering wtf happened because I hit save after I got done. Looks like I'm going to have to go re-log it. What values should I have selected so everything is there since I have to redo anyway?

Can someone please take a look at these ecytek data logs and give some feedback??
Any responses will be added to a comprehensive review of a certain etune vendor.

There is a long ass one with a check engine light at the end with full power loss. The smaller one is some driving with two pulls.

Is your car boosted ?? it help to know what mods you have :-)

What looks suspect is Knock Corrections up to -5 degrees in longer log and advance multiplier dropping to 0.35 indicating regular and quite large knock events

are you running correct octane fuel for your tune ?

read the DTC code for the cel light that does not show up in logs.

Full 2.5' exhaust, Boosted with BOV and EBC Omni Map sensor CEL Code P0068 supposedly running tune for 10psi on 93. Just filled up with 93 from 1/4 tank of 93.
Symptoms = bogging under WOT,
RPM increase when clutch pedal depressed unless selector moved out of gear
bogging below 3k rpm
CEL code resulted in loss of acceleration until car shut off. Would start and run poorly. Then would not start then would start and run okay.

I'm thinking either faulty MAP or bad tuning? Do the fuel trims appear okay?

It looks like Long term fuel trim is disabled in your tune as it zero all the time or amazing good maf scaling.

http://engine-codes.com/p0068.html

could be a heap of things
bad MAP sensor settings in tune if your running aftermarket MAP sensor
faulty maf or map
intake leak boost leak ect.

did you clamp off hoses under intake manifold one might have blown off under boost.

around 3000 rpm is where your getting the knock up yo -5 degrees correction will cause some hesitation as ecu pulls timing and this is with Advance multiplier at 0.3 (it should be one) so ecu has already removed quite a bit of timing.

The Stock 02 sensor scaling does not read AFR richer than about 11.25, so without a wideband you cannot tell the actual afr your running. Boosted cars will run richer than 11.25, but stock sensor will not measure that.

you need to talk to your tuner about those issues.

all that stuff could be rersult of faulty sensor or air/boost leak

I really appreciate the help here. During test drive number 1 I blew off one of the pcv hoses under the intake manifold. I then clamped the 3 under the intake manifold and 1 other by the oil filter. The long file with CEL was test run #2, and the short file is test #3. I have double checked all clamps and connections for obvious leaks. I have requested the tuner check over the logs and will have a revision by Wednesday I believe. I am new to the boosted scene and panic easily lol sitting on the side of an expressway today wasn't that fun. Looks like I need gauges sooner than I thought.
Thank you again Steve99

Ok, take two now that I actually paid attention to the recorder. Cold start, warmup, surface street driving with 1 hard pull.

It looks safe to me.

I've never seen OFT Stage 2 have a solid 12.0 Commanded AFR through WOT. Perhaps someone will know what's going on there.

Anyone up and care to give some feedback on a data log?

http://www.datazap.me/u/darksunrise/...s?log=0&data=1

Looks like my LTFT's are generally -6.25% at idle, and +4ish % above 6k RPM at full throttle.

Mods are:
- OFT stage 2
- JDL UEL catless header + OP
- Berk catted FP
- Perrin 2.5" resonated CBE

I confirmed there are no exhaust leaks (all gaskets are spotless), other than the header flanges which I just re-tightened but haven't checked the gaskets on.

I'd personally be doing a rescale. It's certainly safe the way it is since the ECU compensates, but you're running rich enough to peg the O2 sensor at WOT. You'll get better performance and use less fuel by doing a rescale.

Thanks for the reminder, I need to check my header flanges too. I retorqued everything else and forgot those.

Cool I'll try rescaling the MAF this coming week. Hopefully not too difficult!

I went a bit overboard with the header flanges to be safe (sick of chasing exhaust leaks!) and torqued them down to 30 lbs-ft. You can get a torque wrench in there with an extension and 14mm crow foot.

Interesting going from factory header to OFH in that you don't feel the need to rev it out as much around town, has much more grunt down low. It almost fools you into thinking that it doesn't pull as hard up top as you don't hear the angry VVTI changes anymore around 4k. Just very linear.
