Fix your boost control. You have a boost spike and then boost creep.

Agreed. Do not go any further until you have your boost control worked out. You'll be chasing ghosts around around and around otherwise.

Interesting. I would like to know more about how CVN is calculated, and if modifying ME7 binaries changes the CVN read by OBD.

Note: my interest is specific to ME7.

In particular, do they have a whitelist of all possible ME7 ECU revisions? I assume crossflashing from similar (stock) ECUs is ok? Or not ok?

OP, you are changing the wrong bits.

As I said I'm confused about this. I dont' know if a block CRC can be done in a standardized way. If yes they could do this.

But I find the benefit of block CRC vs simple CVN check is very thin. If a tuner can fake the CVN he will be able to fake the block CRC as well.

Reading the blocks throught OBD won't work for all ECUs. Howerver it would be a killer option as no workaround would be possible then.

So there are 3 options :

-1 CVN check : easy to do but weak
-2 Blocks CRC : more difficult to implement but a bit stronger
-3 Read Blocks : straightforward, very stong but only work for a limited set of ECUs

Code:
[15:30:35] Status : R/W Function available
is interesting as it seems that the ecu is in read/write mode. So it looks like they use option 3.

Another option would be to send the blocks to the ECU and then ask (how ?) the ECU to compare the bytes on it side. This would give similar timestamps. Realistic or not ?
 

I have a question regarding flash and boot mode (ME7) I understand that the EEPROM content is not updated at all when flashing in boot mode. Is it correct ? So there is a problem if CVN has changed right ?

You just need a little more q2 and it will be perfect.

look at your kfldimx in 3d view and tell me it's linear.... it doesn't need to be though it will work fine without it being perfectly linear.  it's just easier to make adjustments if it is.

So, I think I dun fucked something up but I'm unsure what.

I'm starting with a slight amount of enrichment VIA LAMFA (Lean best power just in case I get bad gas and to pre-cool stuff down)
It seems lamfa is doing what I'm asking it to.

I'm planning to dial in LAMFAWKR after I get BTS correct but I'm having loads of issues with BTS. I'm not even sure if i should trust my EGT model to be even relatively close honestly. Even so, It doesn't seem BTS is doing anything that I'm asking it to.

B_tabgbts seems to turn on immediately as soon as I go WOT and stays on after I finish 3rd gear even though I have TABGBTS set to 800 deg C. Are these not correlated? The idea I was going for was: set KFLBTS to taper down to Rich best power and let FBSTABGM enrichen by multiplying. Am I misunderstanding how these operate? Still unsure why it blasts up to stoich at max load.

Anyone have any idea why my AFR's at max load shoot back up to stoich?
