Can't write to JDM evo 9 ecu

[spetsnaz]

Hi Guys,

I'm able to download the map from my JDM evo 9 ecu however when I try to write to it I get the following error

[00:06:18.414] 524288 byte image read.

I'm using ecuflash 1.29a with the Tactrix OpenPort 1.3 cable.

I'm able to read and write successfully to JDM evo 7 and 8

Has any one ran into this problem before.

Please help
