cannot communicate with 2005 corvette
i have a 2005 corvette and i am trying to at least start by pulling the stock tune and every time i am trying to pull it out it has an error... bootloader rejected. reason one of the following- engine speed is not zero -vehicle speed is not zero -a flash memory fault has been detected. any and all help is appreciated im somewhat new to efi so im probably doing something wrong
Hi radical,
Welcome to the forum
Do you have your V2 firmware up to date...?
Install V7 and V8 software from here.
V8 software includes V2 firmware that you have to flash into V2.
i installed the newest software but i dont think i flashed firmware into my v2 unless it does it automaticaly... how do i do that ?
V8 software includes two programs:
- EFILive Explorer (EE),
- Scan & Tune (S&T).
start EE, goto the Firmware tab, and flash bootblock (if it's not the latest), and then flash firmware;
the bootblock/firmware files for FlashScan V2 have filename starting with FS_.
Then when you finished flashing firmware, use S&T to configure V2 BBL/BBF, and V2 settings:

ok set all that up now... if i try with the s&t to read the tune it tells me $0537 the controller is locked with a custom key. if i try to read the tune with v7.5 it tells me something similar... if i select try alt keys then it comes up with the same bootloader rejected error as i stated in the original post
Has the vehicle been tuned before (to your knowledge). It seems like it may have been and the ECM has been locked by a previous tuner.

checked that article my bootblock version is 2.07.01 and says version is ok firmware is version 2.07.09 and says is ok also
vehicle was bought used with exhaust and intake from a used car dealer... to my knowledge i was never told it was tuned but highly possible.
