Good evening chaps

I am having trouble with particular setup - ecu from terrano keeps locking. 
Ecu is made by zexel
23710 2x90
L3
407917-111 1

Its from 2004 terrano with zexel rotary pump that looks surprisingly like bosch vp44.

I want to get rid of immo. Alternatively/additionally how to virginise it? The only info available is to write FF on all addresses in 24c02. 

Attached is the original dump from 24c02

Anyone familiar with these??? I am waiting on t300 delivery next week, but really want to play tomorrow with that vehicle.

How do you make it virgin or which bits are for immo????

[vitasik]

Does anyone know which are the sync bits in that dump?????

I am getting really frustrated with this piece of S******t. Trying to use Nats 5 key utility to read nats itself, I have 3 k-line adaptors, 3 laptops, 3 different NATS 5.6 with according transponders. I cant get connection with nats at all, none of them, from none of the laptops, regardless of the adapter...... 2 of the NATS units came from a known running vehicle. what am I doing wrong????

As for the eeprom 24c02 - there are clips that will help you read it in situ , call me old fashioned I remove she chip, very easy as its only 8 pin.

Tell me guys what am I doing wrong as I am on an edge of torching the lot together with the car.

I have sorted mine. What is your problem?  Describe your immo led behavior as its really helpful in getting right diagnosis.  My immo unit was damaged.
