Using a NATS ECU on a non-NATS Micra

[baguete]

Hi, i was wondering, it is possible to use a NATS ECU on a non-NATS Micra? Maybe using the NATS loom (ignition ring, NATS box and key chip) connected to ECU to make it work?

Thanks

some of the pinouts are different i believe baguete (superls posted the 2 diags up last week) :grinning:

I saw these diagrams and did a comparison, the pins all match up, except for pin 26, used with the IMMO and unused on the non-NATS ECU. It is possible to connect the NATS loom to the NATS ECU and make it work the same as on a NATS Micra?

BTW, does anyone have a pic of the NATS Control Box and the NATS wiring? Thanks

Hi mate, i have that schematic. By seeing that, the NATS control box pin used is number 1, and i can only be a NATS Type5, see it here:

If its in that way, it doesnt use any control box, just uses the box inside the NATS ignition ring, all-in-one. Thats why i want a pic of it in the car to double check it. I think that the 1st Facelifts use NATS 5, and the 2nd Pre-Facelifts use NATS 2 (with simple ignition ring and a control box). Thanks

BTW, your ECU have "1U201" as part code?

my 98 slx ecu is 1U203

the small nats control barrel unit was hidden in the loom beside the heater fan motor and door hinge cavity area.

Yours is an SLX, thought it was an SR. But its a similar part number as my SR ECU.

My 99 Micra doesnt have the NATS box, only a bigger ignition ring box (all-in-one). Do you have any pic of you control box? Its a Siemens part?

i don't, nope.

mine was prob one of the final pre-facelifts before the facelift upgrades

What month of 98? I think that it was in April that Facelifts came...

looks on my record that the blue slx that the loom was from was first registered on Jan 98
