After this mod I start thinking about ecu. I couldn't modify my original ecu, I found a ecu with similar codes, i try buying it.
So,when I got my new ecu, I read eeprom in which is stored immodata (mine was a ST M24c02) and I copied it on new ecu.
Car starts with new ecu
Than a goes to a professionist to get socket on my new ecu
So I could start with my test on it:
First test was:
EGR OFF
I check always my mods with a nissan data scan & consul 14 (modify in 16 pin)
After that I have Swirl OFF, redution of glow plugs timer, start torque, and I tryied some solution of MAF off, But I don't like the injection sensitivity with turbo pressure variation
First I start with AT27C010 but I discovered that those are OTP...so I buy some AM29F010B that could be erased!
