Hi!
I just getting started to modify the maps and I have trouble with my BIN which I read from my ECU. I would like to switch off the Secondary Air Injetion System (SAI), because it's very noise and my pump in on the finish of life. So the problem is that, when I'm checking the original BIN in ME7Check in the end program shows 1 error: "RSA signature failure found -> Found 1 error!!!". I don't know why...what's the problem?

Second question. I compare my "oryginal" BIN to the BIN of the same ECU (file with BIN of this ecu is in folder from ME7Sum) and there are a lot of differences between them. Is it possible that I have a modified engine map for higher power?

I tried to use ME7sum, but it did not fix errors. However, I have read the manual again on the forum and it probably works. The results can you seen in the pictures 


So, I it is possible to deduce how much power this modified map can generate? The previous owner did not tell me about tuning

Okay, I will do logs, but first i want to remove the SAI system.

This is my BIN with zeroed values of MSLUB and MSLBAS. After corrections in the ME7sum and I checked it in ME7check. There are no errors, so now can I flash it to the ecu safely?
