OpenFlash Tablet v1.42b maps now available

[enwave]

We must be getting a good winter blend out here in Utah, cause I started just fine after one crank at 7deg F on the 1.40 maps (not even 1.42 with the enrichment table changes). Plan on flashing up to 1.42 once I have access to a Windows machine again since it will likely get colder again soon.

Definitely got a little sputtering/hunting in the first 15 seconds of idle though. Settled down perfectly after that. E85 is certainly an addictive fuel.

ugh, ran my first autoX on e85 yesterday. My times were about 1-2 seconds slower from where I normally am (based on others that I compete with). The reason? I couldn't get traction! lol. I guess I need to retrain my right foot because my car didn't used to lose traction this easily in the midrange RPM.

Looks like if I can actually get this thing started I'm going back to the changes I made... at least they would get me started in 5 or less attempts.

Unfortunately, until I run in to a starting issue here I can't do too much testing. Also I agree with you that you should test the ethanol content of your fuel. It may be out of the ordinary. I haven't seen any significant starting issue here with the E85 I use. Of course, temps in northern CA rarely go below freezing.

There is an unk speed limit map but not sure if that is actually the speed limit we are thinking of...

That would certainly make the are almost unusable. Easy to do too. If one just wanted to keep the car drivable but no fun, changing the speed limiter from 225kph to say 90kph would certainly do the trick.

There is something seriously going on with my car then. I just swapped back to the 1.4 maps and took a quick log on the way to the store.

LTFT were wildly fluctuating between 2.1 all the way up to 18 according to torque during steady state cruise. It concerned me so I took a quick log.

Advance multiplier sitting at .66 to .7 and AFR at low to mid 11's at WOT. LTFT's sitting at 13 during WOT. WTF

Bad E85 causing this or other issues with the car?

Definitely something going on there. Have you ever replaced your header before? If so, not replacing your exhaust gaskets can easily cause a leak that can result in the fueling aberrations you are seeing in your logs.

I replaced the header on my 05 STi when I had it. Never could get it to not leak and looks like (and I thought it smelled like) I may have one now. I'm going to order new gaskets then and replace them. I did reuse the OEM ones when I put my borla UEL headers on, I've been wondering if I had an exhaust leak or not but my suspicions might be right now. Especially since It's pretty much impossible to get a torque wrench on one of the bolts on a Borla UEL header. Going to swap back to 93 until I get this sorted out. Oddly I haven't gotten a CEL from the codes you turned back on, maybe I just haven't driven it enough to throw those codes.

Thanks Shiv

based on your engine loads, you are getting quite a bit of air flowing through the MAF. Stock intake or no?

[Malt]

Stock intake with a perrin panel filter.

Engine load (g/rev) looks fine to me for cold weather.

Also doing well out here in IL, down to 0 degrees. Blends must make a big difference.

Yeah, it looks really good...is what I was thinking. You are probably right about exhaust leak at header.

[Malt]

Just got back from more logging and I get this... Stuff looks questionable to me at the start but then starts to look better at the end.

http://www.datazap.me/u/malt/12-16-1...t-2?1-2-8-9-11

First set of going through the gears, same crap as before but the next set and subsequent ones...

0.78 LTFT, mid 12's AFR, Adv mut pegged at 1, KC learned value 5.5-6



Ugh, crap is going to make me lose my hair. I don't understand why the LTFT can sit there at 19.5 during steady state cruising right after I do some pulls and get such pretty numbers at WOT.

Just tell me, should I just not worry about steady state cruising because everything honestly looks fine at WOT based on the guidelines Shiv has given.

Really sounds like you have an exhaust leak at the header. No reason you should see such big LTFT during cruise. Assuming you didn't get a tankful of gasoline by accident, that's a symptom of fresh air contamination in your exhaust. I wouldn't bother wasting your time with diagnostics until you replace your gaskets and/or inspect your header for leaks. They really can't be re-used. I learned this myself the hard way
