Guys any input here I'm still having the same issues, boost leak showed a small leak in the tb elbow gasket but that's all airflowperrev is .10 above what it should be and I'm runing rich...I've notice that if I rev it and hold it at 2000rpm it will go so rich (9.x AFR) and backfires. I'm out of ideas... Tomorrow I'll post a log.

Might be able to give input after a log. Make sure to read these three threads before posting a log. If you don't make a new thread in the proper section, I can just move this one there.

Sounds like your deadtime is off, we would have to see a log to tell you anything for sure

Al right I did read the above threads so here I go but please note that I insist that this is not a tuning issue is a mechanical a haven't touch my tune in a while and car was running perfect for long time.
1). Any boost, vac, or exhaust leaks?
Boost leak tested 5psi above your max boost with no leaks?
Yes minor leak in the TB elbow fixed

2). Verified mechanical timing?
Yes

3). Verified base timing?
Yes

4). Ignition system
COP with ARC-2
Spark Plug brand, type and Gap: NGK-BPR6ES/.028

If you are having electrical issues?
No not at all
5). Motor health (Compression Test)
No!

6). Performed basic throttle body adjustments?
Idle Switch: Yes
Throttle Cable: Yes
TPS: Yes
BISS: Yes

7). Compression ratio
8.5:1

8). Any known bad sensors or brittle wiring?
No

9). Any DTC/CEL codes?
Yes- code 1500 for having a 2 wire alternator

10). Electrical system
Car off (not running): 12.5 volts
Car running: 14.2v cold 13.8v warm (battery is logged)

11). Base fuel pressure and injector values
Base Fuel Pressure: 43
Injector Size (cc/min): RC750
Deadtime 320ms

12). Properly calibrated and configured wideband sensor
Sensor Brand: MTXL wideband
Calibration Date: a couple months ago

13). Type of fuel
Type: 93 Octane
Percent of Ethanol: 0%

14). Watched ECMlink how-to videos?
Yes

It doesn't look like you've done any airflow tuning via the Speed Density tab to bring down the high AirflowPerRev value. And at idle your CombinedFT is way off (-27%+) so you obviously haven't got into adjusting the deadtime. Get your idle dialed in and then see how the car reacts.

Yes, you are right I haven't touch the VE tables, I will do what you told but please take a look at this log too if you have the time. Is the exact same tune on the same car same mods nothing changed since october last year!

I do see what you mean, but if nothing has changed, I can't think of what to suggest to look at other than just tuning it.

@Calan any ideas?

On the 2014.10.18 log:

At first glance, it looks like something is up with your fuel flow. During the period from 34.8 to 40.2, airflow, RPM, and injector PW are steady, and the front O2 and fuel trims are acting like they should. BUT...your wideband is jumping all over the place. Since you actually feel this, it's not simply the WB flaking out....the lean spikes are real.

Looking closer though, check out your timing signal. It looks like the ECU isn't able to adjust timing consistently, possibly due to a bad CAS or intermittent signal getting to the ECU. The timing jumps every now and then like normal, and then flatlines at a perfect 5*, as if the ECU is locked in diagnostic mode.

On the 2015.02.17 log:

Combined FT is maxed out, O2 stops cycling, and IPW keeps increasing. The ECU is fighting to keep the AFR in range, and finally reaches the end of it's adjustment, so AFR goes steadily more rich. First thing to do is get the CombinedFT at least close, so that the ECU has something to work with.

****

I would look into that timing issue first. I don't know why it doesn't show up in the earlier log, unless it is just that intermittent....or I'm missing something obvious. Since you were using the same VE table in both logs, and it wasn't calibrated in either one, I think you are looking at a combination of things. Why it ran decently last year is what I'm most curious about. Based on that 2014 log, it wasn't running good at all.

Thanks to both for looking at my logs indeed in the last year's log timing goes *5 and then comes back just to go flat again never noticed that.
In the latest log the timing is acting like it should right? I'm still going to check is if there's something wrong with the CAS and CPS and their wiring.
Now should I adjust combinedFT via the VE tables or deadtime? I asume VE since my airflowperev is also off!
Just to add to this I did had an big oil leak in the timing area where even the belt got soaked in oil and had to fix clean and replace, I didn't replace the sensors tho actually I didn't even touch the I just unplug them to remove the covers. And since then i feel like this issue got worse actually it gets worse every time I turn on the car!

Use this video to help get your idle dialed in. Instead of using the MAF Comp sliders, you'll use the Speed Density table (use Track Datalog to show what cells are being used at idle).

Thanks Brian yes I've seen those videos multiple times anyway as I'm writing this I'm in the car tuning I managed to drop the CombinedFT in the +/-5% depends on the rpm sometimes goes 0.x% but to archive that I had to drop some VE cels in 40s range might sound like a noob question but is this ok?
Sorry for these long posts but here I'm on my own the internet and you guys are my only help!

That sounds fine to me as long as AirflowPerRev and CombinedFT are in check.
