I'm beginner here. Nice to see many experts post
Now I use MY05 WRX EUDM (A4TE300D) AJ830-8820 and just read ROM
by EcuExplorer via Openport1.2 . I show my original maps in the attachment.
Please suggest me that , after decat 1st , 3rd cat and change backbox & intercooler to STI ,can I reflashed "AJ830Pro_192k.hex" to my ecu?
(just convert AJ830Pro.zip to 192k hex file and don't edit it)
