UK MX5 Sebring SC owner here!
 

Hello Miata owners :)

I am here on the hunt for some information to repair my car, and also to get some inspiration in to what to do next!

Here's my car:

Attachment 197031

It has the Sebring supercharger kit, and BBR piggy-back management. I want to junk the management as it's not doing it's job, and badly need to find the pinout for it!

This is the ECU in question:

Attachment 197032

Those wires go inside the ECU and are soldered in place on to the main board, not just spliced in to the ECU loom :(

If anybody can help it would be much appreciated, I'll post this is the relevant section too :)

Thanks for having me here, and thanks for any help.

I would just remove the whole setup and get a MSPNP. The other option would be to just go buy an ECU from a scrap yard.

I have a whole doner car, but due to the unique way the immobilisor seems to work, even swapping the ecu and ignition ring, putting the correct key in the ring etc, the car gets cut off by the immobilisor.

I want to remove this box as a temp measure while I put in a powercard and Bipes, as a fault finding exercise, the car just isn't running anything like it should, and I think this gadget is why.

Before I splash out on a Megasquirt or Link, I want to try this known good option I have at my fingertips to make sure it isn't some other fundemental problem :)

Thanks for the input though, you're thinking along the same lines as me, promise :)
