I bought the ecu that supposedly had apr on it, but it never made more power than stock so i assumed it was bs.
Do you try to activate tuned part of ECMS with CCS-Switch?
If not, than ECU will operate as stock.
I opened the ecu up to mod it for boot mode and i found that same chip.
Im assuming it can be read but not written to?
You can read only 1Mb stock part of 4Mb-APR flash in standard boot-mode.
You can't write or change something in this dother-board in boot.
