Solution for fgtech 4 v54 simos pcr 2.1 unlock ecu error
 

I have simos pcr 2.1 ecu , i want to unlock but with fgtech 4 error unknown ecu

I think dashboard on / off problem
12v charger I put, but one extra batter supply given or not ?

Working Solution:

Remove 25640 put in programmer and unlock refit write ecu obd…..

Apply 12v dc adaptor to fgtech, not battery supply to fgtech.

Add only 2 resistors, not 3 ones.
560 ohm and 1K ohm and one wire to make a bridge.

Hi,

I think you problem is that device does not support BRZ\86 ecu. The ecu in brz\86 is a RENASIS SH72531 based not motorola or denso ECU.

The cheapest device to reflash these ecu is a Tactrix see www.tactrix.com
and link below TACTRIX INFO FOR ECU FLASH

Or spam??

Post count and location might give that away ;) Too eager to help mate....
