Hello all,

I've had a look around on the forums here for awhile and I might have missed this info but I can't seem to find exactly what I am looking for.

The Nissan DataScan software has a Map Trace feature, which as I understand it, shows what cells in the ECU Fuel Map are currently being referenced by the ECU while the car is driving along.

I'm trying to make this work for a 1999 1.0L K11, which I *assume* is running the ECCS ECU, not MoTronic ECU. This car does have NATS.
Connecting the data cable and running Nissan DataScan does allow me to view information which seems to be correct.
I believe I need some ROM Addresses that work for this ECCS ECU so that Map Trace will read correctly.

Taken from this website: https://www.nissanclub.com/threads/nissan-datascan-map-trace-addresses.262361/ as an example for a 1993/1994 Altima:

Does anyone have these address for the 1999 1.0L ECCS ECU ?

Another quick side question, does anyone know if this ECU is a 32kb ROM size or 64kb ROM size ?

Thanks all
