MS2PNP & Sequential Injection
 

So I have a 1993 California based Miata, which apparently comes from the factory with sequential injection.

I was wondering if any additional wiring was necessary in that case to use the sequential features, or if I just change the settings on the tune?

I am using the MSPnP2/Extra.

According to megasquirts website, the unit I bought should have come preassembled to accept the sequential injection; "Up to 4 fuel injector channels with individual trim tables available in sequential models."

Edit:
So after some more review I've ran into the fact that I do indeed need to do a wiring change, though I am a bit confused about which jumpers need to go where?

Also can I retain the factory wiring which is currently utilizing the z2 and y2 slots?

For this particular application, all you have to do is enable it in software. The car is already wired for sequential injection.

So I can disregard this post, and leave it wired as is and jumpers in their original position?

Thank you.

Right. If you are using peak and hold injectors, you will want to remove the Inj Qty jumpers from outputs A and C.

Thank you Matt.
