you wont be reading that ecu with nefmoto or any other software. nefmoto is me7 only and that ecu is m5.9.2. if you really wanted to you could remove the chip and dump it in a chip burner but i wouldnt waste my time. you can write to the ecu using mpps
Thanks. I remember Giac soldering chips on for tuning. Can someone tell if that is a Giac (or other aftermarket) chip?
I have 2 other 557P, those were flashed with MPPS (Daz initially, I think later Mirza), I forgot how they performed. Only wrote down 18 psi, readiness checked and 'tune outs'. So assume stage 2 tune. Don't have a car anymore to test them.
