NVRAM Adapter

Post by jamez70 »

Hello all,

I'm creating an NVRAM plugin adapter to replace the 27SF512. I reprogrammed my ECU (7247) to allow Mode 5 as code upload and it works great.

I may professionally spin about 10 boards, and was wondering if there is any interest in them from anyone else?

Its an American pcm. I'd be happy to add support for it to the OSEPlugin for Tunerpro 5 if you wanted.

Same goes for the flashtool if your using a similar frame format to the write modes I have added to the aussie bins ...

Byte 1: Device ID
Byte 2: Number Of Bytes
Byte 3: Mode
Byte 4: \
Byte 5: / Destination Starting Address
Byte n: Bytes To Write (anywhere from 1-128 depending on the ECM)
Byte n+1: Frame Checksum
