Is there a way to pair a new ecu with my old immobilizer?
Certain code or??
Any help would be great.
Thanks
Daniel

Just resolder 93C56 or 93C86 8pin chip from old ecu to a new one if both ecu's are Denso and use the same chip.

No way of re flashing or anything? Im told EcuTek can do it.

Just copy immo sync region in 93C56\93С86 EEPROM by an applicable tools.
I have to say a solder is the most inexpensive tool move immo on to another ecu.

Just verifying, is this the correct chip (2006 WRX ECU)? On my ECU, the label was pretty hard to read. Attachment: eeprom.jpg

This is correct.
Most probably labeled 93c56.
Some JDM\USD may have 93c86.
93C56 and 93C86 chips are not completely compatible but immo sync maybe copied from one chip to another by means of an applicable programmer.

Just copied mine via eeprom. Worked a treat.

This is an old thread but I wanted to say that I just switched the EEPROM's between my old (water damaged) ECU and a new one I bought on eBay.
Worked great!
Thanks OP!

Anyone know if the eeprom next to the IC402 is the correct one for the newer 08+ ecu's?

To get a replacement gauge cluster working, would the eeprom transfer/soldering work? same 8 pin chip?

Been successfully copying eeproms to match immobilizers.
But does anyone know if you can virginise the ecu? So can throw it in a car without pulling old ecu??

i don't think there is a virginise type setup for them, any ecu even brand new from the factory will need paired with the car your putting it into.

Hi Guys,
Im changing clusters from and 04 Legacy to 07 Legacy.
What is the sync region to copy from and L56R to a 93C76.
Or is it possible to solder L56R from 04 cluster and replace the 93C76 from the 07 Cluster.
Dumps of both chips attached. Would also like to change the klms from 70K to 250K
which is on the 04 cluster.
