Anyone know what this is?
« on: November 05, 2013, 02:36:46 PM »
So I tried writing a flash to my 2000 c5 a6 4b0907551k ecu I tried writing a mbox file with mpps failed, tried galletto to write fail. So I opened the ecu and noticed this the chip has Hy29f800bt-70 chip. Nefmoto has a memory layout for the 800bt but is this it? Also what is the plug for? Was this chipped by what anyone can tell? If this is the correct chip can I write the mbox file I have? Thanks in advance

It's an APR gen 1 EMCS board.
It must be removed, and the ecu returned to stock before it can be flashed with nef. I do quite a few of them.

Yes, as long as the speed of the chip is correct.
29F800BB-70SD are a good fit and readily available on ebay.
