I am having problems trying to wire my up my diypnp ver 1.5 board for sequential fuel injection. I cannot find a pin out diagram for the 94-95 Miata.

I can only find 9697 which shows as:

Batch: INJ1 4U,4W
INJ2 4V, 4X

Seq: INJ1 4U
INJ2 4W
INJ3 4V
INJ4 4X

My best guess for the 9495 then would be:

Batch: INJ1 4Y, 4Z
INJ2 4U, 4Z

Seq: INJ1 4Y
INJ2 4Z
INJ3 4U
INJ4 4Z

But I really don't want to guess, If anyone has a pin out for the injectors I would greatly appreciate it.

Thanks in advance.

 

Here are wiring diagrams.

 

Thank you. From I understand, on a 95 us Miata harness

INJ1 2U
INJ2 2V
INJ3 2Y
INJ4 2Z

Now I just need to trace back the jumpers on the MS side.

 

Ok, my educated guess for a 95 Miata is now

Sequential fuel injection:
INJ1 4U
INJ2 4V
INJ3 4Y
INJ4 4Z

Does this seem correct?

 

After getting a reply from diyautotune:

"The injectors would wire corespondent to engine firing order. If your firing order is the typical 1-3-4-2, then injector 1 output would wire to cylinder 1, injector 2 output to cylinder 3, and so on."

Based on this, my new plan is

MS Board_____MX5_______MS
INJ1_________2U(INJ1)___4U
INJ2_________2Y(INJ3)___4Y
INJ3_________2Z(INJ4)___4Z
INJ4_________2V(INJ2)___4V

 

I got it right!!!! It idles so smooth steady now. Now, on to the 6 speed, more boost, and 3.6 gears.... Man, every time I think I'm getting closer to finishing the car....

 

What settings did you use in TS?
