Thanks.

At this time, you will not need ANY computer to use the OFT as it will come pre-loaded with maps for all different ROM types. Just plug it in and select what Stage map you want to run. But if you do want to modify the maps or download datalog files to your laptop, you will need to run Windows OS. Personally, I use a MacBook Pro running Windows through Parallels. Or you can run Windows through Bootcamp which comes with your Mac. Easy to do and probably more stable/better performing than running Windows through a PC

Which suggest that there still might be air entering the exhaust system at the header flange/head connection. I'm sure you will see positive fuel trims ramping up with more driving time. The only solution to get your trims in order would be to fix your header once and for all (assuming you think it is still leaking).

That is not good news

Would some residual E85 in the tank on fill when swapping from the E85 maps to a normal Stage 2 gasoline map cause a lean condition until the LTFT's adjusted for it? If so it doesn't look like they have moved from 0 during WOT yet. I'll drive some more today and log again tomorrow to see how much it adjusts. If the leak is still there I'll cough up the cash to get a shop to install them because if the leak is still there apparently I can't install headers correctly (or the flanges are warped).

If you have some residual E85 in there, it would certainly result in temporary leaner AFRs until LTFT kicked in and brought AFR to the target range. But it shouldn't take too long for things to get into the desire range.

Ok, thanks. Just checked google maps. It had 8 miles on the reflash when I started logging and put another 8 on it during the log. Not sure if 16 miles is enough time for it to adjust but I'll check again tomorrow after I put ~50 on it tonight.

Sigh... I think you are right shiv, but I'm going to at least run this tank out to make sure the higher ethanol content isn't causing all this weirdness. Is there anything else that would cause LTFT's to jump around? DI seals, Intake leaks, etc? Logs coming home from dinner look semi fine to me on the highway. LTFT is a tad high but stable. The one pull I did getting on the highway had AFR's in the low 12's this log.

Here's a log I took from last night. From around 6000rps WOT LTFT climbs up to 14% and stays there till redline and goes down to 8% at idle, lower rpms and low load conditions. Doesn't look to be an vacuum or exhaust leak. AFR is lightly richer than target AFR's.

I had the Advance multiplier value go down to .0 from around .8 couple of times (not on the log). How much does the engine have to be knocking for that to happen?

Mods: afe drop-in filter, cut intake scoop, a catless J2 front pipe and v1.42 STG 1 OFT.

This might be a stupid question.... but... I'm having a hell of time trying to update my OFT. This is my first time using Windows since the 90's... so that might be the issue. I'm on 8 and I ran the update for 8.1 and I believe I installed the patch. Anyway, when I connect the OFT and it searches for updates, it find one and then when I click okay to update it I get an "Updater" error. It says "Unhandled exception has occurred in your application...
yada yada... The process cannot access the file '.\\updater.exe' because it is being used by another process."

Any ideas?

The LTFT at WOT and high RPMs had gone up as high as 16.41% today. Any ideas, Mr. Pathak? @shiv@vishnu?

Shoot me an email at shiv@vishnutuning.com and I'll send you a new map that seems to sort out the high LTFTs that some cars are seeing. I'm out of the office this during the holidays but if you send me an email tonight, i can probably send you the revised map tonight as well.

Yup catless J2 front pipe, aFe drop in filter, and trimmed snorkel. All else stock with a 1.42b stg 1 OFT tune.

I did keep a bit more material on the snorkel than shiv and others. Although I'm sure that's not going to change much.

Are you running the last version of OpenFlash Manager 1.04? It's be available for download for approx 2 weeks. If you are running an older version, just remove the version you have and reinstall the new version that can be downloaded from HERE.

Sound good! Thanks shiv!

I screwed this one up the first time around, but yeah, iam, fbkc and flkc would be nice.
Don't know why no one pulled me up on it. Guys, if I say the wrong thing, feel free to correct it.
