Ecu swap Bmw e36 318i 0261203278

[Leeetoyo]

Hi guys,

I’ve got a ecu to swap on a bmw 318i convertible ‘95.
I have old damaged ecu which injector feed is shorted out.
And I have a used replacement ecu with all the same numbers.

I have been looking for immo off solution but that’s hard to find and maybe not possible?

I think I have these options:
- sync ews and ecu but don’t know yet with what tools that’s possible?
-swap flash from one to the other ecu.
-make ecu virgin.

Why is best way to swap ecu?

Immo off is possbile.
For you... just swap eprom (27C256) and be done. Max need sync ews+ecu with inpa.

repair it, injector feed is probably darlington driver on 1 of the heatsinks, trace pin and you find it

This type ecu doesn’t have the 27c256 eprom. Already tried to go that way, no succes..

I have searched on the pcb for burns and odd spots but nothing to see.

What can I look for at heatsinks?

Sure it got... lift the white bracket... there it is, 32kb read... DIP28 eprom (Number on Sticker start with 1267....) . There is all immo data inside the eprom. I done several of em also ews delete without emulator.

you will not see visual damage on them..

take off clips and make measurements with DMM, 1 of them will give other value
