Data Logs! Post them here.

[Susurs]

Hello everybody,

this is my first post in this forum. Usually, I'm active in the german forum for BRZ/86 owners, so please forgive me to post a question here without further introduction of myself, which I'll do later.

Recently I purchased the OFT and started to test the OFT OTS Stg1 tune on my car that is basically stock on the drive train except for a Cosworth air filter and a N1 catback exhaust. I'm currently driving on non-premium 98 octane, which I assume is similar to US 91oct.

Because I just started learning to read and interpret logs, I wonder if someone in this forum could take a look at the logs I've recorded with the OTS and Wayno's v98 map that I customized for my A00G rom to be sure that the engine runs safe. Currently, It's about 35 degrees Fahrenheit. Once it gets warmer, I'll also try 102 octane petrol and E85 (of unknown quality) as well.

This is the log from the first drive after flashing Wayno's work (city and highway):

These are the logs for city driving using the OTS OFT v2.07 Stg1 map:

and this is a 3rd gear pull when driving conditions allowed it:

What do you think? Is it safe for me to drive with these maps?

@Susurs I only looked at the third gear pull, but your AFR looks safe, and you don't have any significant knock correction that I can see. You want IAM at 1, which it is. In the future log FLKC.

So from my knowledge, your tune looks safe.

Hey guys can someone shine some light on my 2nd and 3rd gear pulls. much appreciated

Thx! I'll log FLKC in the future and post a log once it gets warmer here.

I just put an open flash header on and I flashed OFT stg2-93oct-UEL with Wayno's load limits quiet start and fan mods. I have an A'pexi drop in and a Greddy supreme SP cat back. It's only had about 10 miles on the tune but I thought I would upload the log's. http://datazap.me/u/oldgunfan/stg2ue...-2-3-4-5-6-7-9

You have some significant knock and IAM drop, what tune/fuel are you running?

I'm running shivs esc tune since since i have a phantom super charger. i'm running 91 oct gas (chevron). I have no clue what it could be as i have open flash headers as well.

Possibly the attack of the "winter blend." dundundun... You need to log a bit more data, but I wouldn't be surprised if fuel quality or exhaust vibration has something to say about it.

I dont know why youre logging widband AFR as it's just flatline. And engine load is not being logged. I'd like to see the cam timings as well. The lean spot where maf voltage go up suddenly at 3000 rpms does not look good allong with the peak maf voltage being only 4.08v. I can hit 4.13v totally NA though the esc might have something to say about that. http://www.datazap.me/u/shaynek/log-...-10-11&mark=11

I will log another pull and get back to you.

I've got some more data. I'm running Stage 1 EL E85 my ADV is less than 1, do you think it is safe to have the tune on the car?

This was the one where i noticed the ADV was than 1.

http://datazap.me/u/jlim7/knock-2?log=0&data=1

I tried to keep the rpms as much as i could.

Looks to me like your E85 is more like E45.

There has been a couple of times where I filled the last bit of the gas stations gas.

Should I go back to 93?

I'm not an expert but for reading the forums i have seen E85 that should be 85% ethanol it more like 60% and because we have had so much rain and ethanol absorbs water you may have bad fuel. By the way where are you getting 93oct gas in Atlanta? When i'm down there all I can find is 91 E10 or E15.
