Ok, so few days ago i bricked my ecu flashing non checksummed bin.
Shorted out the ECU while hanging on bench, great O_O

Bought a spare ECU, and immo off + flashed original bin.
Finally can continue fixing the overboosting.

Currently i'm having this in logs, i don't really understand what to change to compensate spikes.

Also I really think you should flatten DIMX quite a bit. You have falling boost request anyway.

Lol, you will definitly not blow up the engine Cheesy the ecu has many foolproof methods programmed to prevent this unless ofcourse you disable it like the Boeing guys did Cheesy

That is literally the last thing you want to do. Not because you'll blow up your engine, but because its pointless unless you do all of the work described in the thread.

Much better. but keep extend the flat imx down to 2500rpm or so.

Also, there is something very wrong with your DRL. it should not spike to 95 at input of 65, that is what is causing your oscillation.

Can you log wgdc prelin?
