Hi I just got my Efilive flashscan V2 and was trying to read teh calibration file on the pcm, but it keeps coming up with Error: Bootloader Rejected. DOes anyone know what it going wrong? This is on a 01 Yukon and I believe it's the untouched factory pcm in it, thank you in advance.

 

have you tried to read the pcm again?
Every now and again mine will act funny, so i just try it again and it works fine.

 

Yea, I tried it again after the 15sec delay, restarting the computer, and restarting the car. The scan and logging part of it works fine, and it says the computer is not locked and has a standard key.

 

Make sure you selected the right controller type (99+LS1)

 

also if you have an aftermarket stereo it wont work sometimes..pull the radio fuse

 

I selected 99+ genIII, also tried all the rest just for the heck of it and the others get Bootloader Rejected: can not unlock....

I have a factory radio, all my e-fans and other high current draw items are unplugged

Here's what happens on the 99+ genIII

I appreciate all of your assistance, never knew that it was this hard to just read the pcm.

 

Have you down loaded the latest version of the software and updated the Firmware on the V2 itself? I know there was just recently some changes to how V2 connects to the PCM and that may be your problem. I would also post this over on there forum too.

 

I checked that and it is the current version, should I reflash it anyways? Being new to the forums at Efilive they still need to approve the account before posting privilages are given.

 

Thank you very much kbracing69 reflashing did it, if I would have known this earlier five hours of fustration could have been saved.

 

No problem man
