Hmm, it feels less peppy down there to me. Seems about the same everywhere else though.

I just loaded 1.3b as well and it does seem not to have that pull right before 3k rpms anymore.

Another thing I noticed is the crickets seem to have gotten really loud after loading 1.3b. When I go to start the engine it would chirp very loud on a slightly warmed up engine. The kind of loud chirping that would only show up after being run very hot (track and/or very hot ambient temps) with the factory tune. Not sure if anyone else is also getting this.

You can do a file comparison between v1.3 and v1.31 and you'll see the only change is ignition advance map at moderate to ful load below ~3500rpm. This should only effect ignition advance learning during those load/rpm conditions. Definitely won't make a difference to any cricket noise issue. For those who prefer the feel of the earlier map versions, by all means still run it. Next revision I'll see if we can add more timing down low without sacrificing stability. Buy this is the stuff end users can do themselves once we enable datalogging/viewing.

Awesome! Can't wait for the data logging features. I also noticed that the OFT auto updated something when I plugged it into my laptop to load the new 1.31 map.

Edit: I actually went from 1.2 to 1.31. Did not get a chance to try 1.3.

so do i remove the o2 spacer?? anyone?

there's no way the tune did anything to your crickets. Probably just some especially ethanol-y gas.

Yeah, I did a file comparison and that's how I found it. I'll leave 1.31 on there for now as I'd rather have a bit more knock correction than that tad bit of extra pep down there. Once datalogging is enabled I plan on testing minor changes to that area.

I have 93 here. Any reason i shouldn't just use 1.2 based on your observations of 1.3?

I say run whichever one you prefer, and once datalogging is here, fine tune it a bit. If anything, 1.2 still felt safer than the stock tune.

I cant find the 2.0 tune. Is it still up?

If you download either the 1.2 or the 1.31 beta map files, you will find both stg1 and stg 2 in the zip files.

Got it. Thanks!

@solidONE not sure about cali but i'd imagine winter blend fuels have started showing up in most places. that or just higher ethanol content.

I run ethanol free myself.

Updated to 1.31 today, and decided to add some 101 octane to my tank. I can't get over how fun the car is with the bump in octane, just wish it wasn't so freaking expensive ($7.50-ish a gallon)

Also, I've modified my intake snorkel, see below
