Fair enough, is 50 miles enough to get a good log? Not trying to be difficult, just truly don't know how the ecu learns and how fast.

50 is probably the minimum for a log to show information that is useful. Obviously the longer on the flash, the more time your trims will have had to stabilize.

EDIT: Also you can change what you log. It probably would be helpful to log FLKC and knock correction instead of VVT intake and VVT exhaust. If you are seeing some knock correction or FLKC then that would explain why your IAM is below 1.

For the sake of science, I took another log after 40 miles total on the tune this time logging FLKC and KC. The adv multiplier is now at .72. So we're headed in the right direction. Thanks Malt for the advice, I'll log again at 75 and then 100 miles.

To speed up learning do about 3 easy steady partial throttle (not wide open) runs in 2nd or 3rd gear from about 2000 rpm to 5000 RPM and your IAM will get to one.

the knock looks pretty minimal, but with your driving below 2500 rpm steady throttle then just going WOT to the higher rpm the ecu is not getting to learn, it learns much faster in "closed loop mode " ie steady throttle driving/cruising (non wide open throttle) but you just need to up the rpm a bit while your cruising.

Does everything else look ok now?
Thanks

Yeah look pretty good, shiv tune always run on the rick side higher rpm your high 11's so that pretty standard for oft tunes

there is a very small amount of knock about 6400-6500 and a bit about 6700 rpm see the chompy bits out of the kc learned curve. The FLKC logging is still not working but you can work it out from kc learned. Looks like is only about -0.7 degrees so it probably ok and the fine learning knock control will probably sort that after a bit more time if it keeps happening.

Is it normal for my ltft to be around 15 at idle? Im on my second tank of e85 and noticed that my ltft rose compared to my first tank which stabilized to lower than 10 which Ive read would be safe. Should I reflash and start again?

That's not normal. Do you have an aftermarket intake? LTFT's should be +- 5%

Just picked up my OFT today. So I'm using the B01C map, can I upload the A01C map with LC, FFS, and the rest? OFT won't even let me put the A01C map on the device itself?

No. You have to use the maps for your CalID.

No stock intake, recently installed a hks drop in filter though. What should I do?

I'm not saying you have an exhaust leak, but those trims are exactly like what I had when I was running E85 and had an exhaust leak.

Interesting. I really don't think I could possibly have an exhaust leak. Could it be the filter? I made sure it was installed correctly and sealed properly. I really don't know what to do. Can i damage the engine running this way?

The first thing I'd do is take some logs and post them up to datazap. People much smarter than me could look at your logs and determine if there really is an issue.
