How are you people able to download the maps? Are you using the ConsultII protocol or dumping it from the microprocessor?

The Nissan reflash software uses J2534 adaptor which is based on KWP2000 protocol. The reflash is done after gaining securityAccess through seed and key authentication. The data send to ECU is encrypted so it can not be captured and the requestUpload command (0x35) is not implemented.

Can anyone shade some light?

Thanks,
Tom

I can reflash any 2003+ Nissan /Infiniti now (finally!)

Done years of research and finally got it down. I made a kernel to read / write and can modify every map, disable dtc's and even disable NATS (anti theft) so you can install engine in any other car with no worries.

If you are local to Southern california I offer this as a service bringing the car to me. If you don't live in SoCal, you can mail me ecu and I can flash to your specs and send ecu back. PM me for more info if interested. Works on all SH7055 and SH7058 Nissan ECUS (2003+) This took me many many hours over past couple years but finally got it down.

The system I use cannot be easily made but I can help people if they want to tune their nissans.

Also can disable the Drive By Wire sensor by wiring a 0-5v TPS to throttle body, runs better, less lag
