I was just looking at the diffs between your rev3.1 and rev2. The most likely candidate to me is timing. I'd be curious if you set the timing maps back to stock if that wouldn't help. The other maps that seem to make sense are ldorxn and ldrxnzk. Although you shouldn't be hitting over boost because of your KFDLULS changes..

Sorry I can't give any more help here, I haven't tried a full launch on any of the revs yet. Partly because I don't have a good place to do it. Partly because I'm a chicken : ) I'd like my drivetrain in one piece, thank you.

Went ahead and tried 3.2 on my bone stock car. Everything flashed fine, started up, drove a bit... Car drove like a bat out of hell. During one 3rd gear pull the car went into limp mode, no CEL. I pulled over tried to read codes, and couldn't get a connection to the ECU. The car wouldn't start up either 

Disconnected the battery for a few minutes and it started right up, but as soon as I shut it off and tried to start again... no dice. Same deal, no ECU connection, and it wouldn't start.

Went ahead and disconnected the battery for a bit, got the flasher to initialize and flashed my old file back on. All is well again. Just not as quick...

Anyways, just wanted to report on my fun tonight! I don't know if I did something retardedly wrong or what, but dang I sure want that tune to work!

edit: after all was said and done and the original tune was back on I pulled this code

17964 - Charge Pressure Control: Negative Deviation
        P1556 - 35-10 - - - Intermittent

I just tried rev 4 with the same result as 3.2. I must be doing something wrong! I'll attach my log and my original backup file (that works every time I flash it luckily so I'm not stuck!)

Workflow:
Connect everything, Nefmoto open
Car ignition to on position
Connect
Flash new file
Get the success dialogue
Disconnect (with button)
Ignition off
Ignition on
Scan for DCT's and clear P1602
Start car once and it's good
Start car once more, and nadda
Nefmoto won't connect to ECU

Disconnect battery, connect with Nefmoto and flash original backup file and everything works as it should

I didn't take it for a drive so I didn't give it a chance to hit limp mode.

As far as the checksums go, I'm on a new computer and haven't reloaded the software to manipulate anything yet. Just have the flasher... I'll have to find time to get that stuff up and running again.

I'll give you 91 oct logs as soon those updated files are up!

I realized I have no idea how to really modify the bin files at all, let alone update the checksums. I've only played around with the software, I need to read some more...

I verified checksums in the two files posted with my own checksum software and they are all correct.

What was the problem? I'm also using the MTX plugin but have not had any issues. Was it a config problem or is there an updated plugin that I should be looking to get?

Went ahead and flashed rev 4 onto my stock S4 (I'm running 91 octane). Initial impressions are great! Everything so far has been smooth and seamless, haven't hit a hiccup yet.

When I get some time I'll run some logs. Which blocks do you want logged specifically?
