Can anyone tell me if this looks safe/acceptable for e85 tune?

Just learning myself here, your fuel trims are within the ±5 range so that's good. Flck was minimal and your advance multiplier stayed at 1, which is great.

Yes.

The 1st lot of data for MAF1 was minimal. To get the best results you should reduce the dV/dt parameter but this requires more logging time as you discard more. I tend to set mine to 0.3/0.25 but then I like logs of 45 mins or longer when I do this.

Should I flash the MAF1 rom or MAF3 rom if I wanted to do more logging to scale the maf and improve it?

No matter which one you do, the results should be the same. However sense would suggest you continue with the most recent and therefore the more accurate.

First time posting in here. Just installed Borla V2 UEL yesterday and flashed the Stg. 2 UEL E85 Tune.. Let me know if everything is okay . Idle and cruising:

I think I've done this right. Never used datazap before but here we go

EcuTek
Sprintex SPS 210
700CC DW injectors
Zeitronix flex fuel

So I'm a total rookie at this but I've been lots of reading and experimenting lately to try to optimize my tune over the past few weeks and wondering if anyone can guide me in the right direction to smooth out the flkc and fuel trims even further.

I started off with the OFH 93 tune as a base tried applying Wayno's settings to see if I'm getting better results.

I'm running the following parts:
- auto transmission
- JDL catted UEL header
- stock overpipe/frontpipe
- TRD catback
- Perrin drop-in filter
- gas is Chevron 94 octane

Here's the logs for the following:
original OFH 93 UEL tune: http://www.datazap.me/u/gawesome/201...data=1-5-11-12

original OFT 93 UEL tune: http://www.datazap.me/u/gawesome/201...data=1-5-10-11

OFH custom tune with Wayno's auto throttle map, always-on radiator fan, 'Stg2 UEL 98 v101.AU.Rich A01G UEL' base timing b and AVCS tables:

OFH custom tune with Wayno's auto throttle map, always-on radiator fan, 'Stg2 UEL 98 v101.AU.Rich A01G UEL' base timing b and Shiv's JDL E85 AVCS tables:
http://www.datazap.me/u/gawesome/201...0&data=1-10-11

So from my rookie observations, all seems to being dropping IAM slowly with the 1st custom tune being the better of the 3 tunes. It looks like the OFH custom tune with Wayno's maps seems to be less erratic with flkc with the exception of the ltft being weirdly higher at -8 compared to the other two around -4ish which I don't really understand. I haven't scaled my maf yet btw for all 3 tunes.

Or maybe I'm just starting with an overly aggressive tune since I did use the OFH tune. But IAM and flkc looks worse on the OFT tune though?

I'm wondering if the erratic flkc at higher rpms be a fuel issue? Or is this something that just needs refining? I could try to fuel up with the next best gas here (Shell 91oct) and reflash with a 91 tune to test it out.

@G-awesome the calibrations you've loaded are typically used on non-catted header setups, I believe. So, it may be that the ignition advance is simply too aggressive or the acvs table not well suited for your setup. I'd load a stg 1 calibration and log just to see if the flkc goes way. A number of different things can be causing your problem though. Exhaust vibration due to improper installation, bad gas, unsuitable calibration. Although the 3rd log using wayno's 98ron cam and ignition calibration looks the least worrisome.

Good point! I've been obsessing over the stage 2 UEL tunes since I got the header installed that I totally forgot to give the stage 1 a shot again.

If the stg 1 come turns out to be free of knock (relatively) then you will have ruled out the vibration cause. Though, with a stg 1 calibration i think its safe to say you will not be taking full advantage of your headers. I'm sure ideally it's somewhere between a stg1 and stg2. Or you can try to find somebody with catted uel headers and use their cam and ignition maps as a starting point.

Do you guys use a software when analyzing the csv's or just know what your looking for .-.

Hi!
here is the log i made during track session yesterday. Tuned by OFT based on v.101 Wayno's tune (+ custom MAF scale). my opinion the engine was working properly:

http://datazap.me/u/ondreiko/mrw-log...zoom=7419-7481

and i am going to make some final minor changes to MAF scaling (as excellent VGI's tool shows) in field of OL mode basing on this log.

[Wayno]

Would be quicker to just multiple 3.71 and 3.91 cells by 1.01 and call it a day. Don't need any tools.

looks like I'm still dropping iam and flkc with the stage 1 93 uel tune...hmm http://www.datazap.me/u/gawesome/201...data=1-5-10-11

looks like I'm gonna check the hardware for leaks, vibrations, etc.
