megasquirt 93 CA miata ???
 

will my 93 CA wierd miata work with a diypnp mega squirt that was ordered to work for a 91??? i know the fuel injector wireing is changed a bit for 93. please any one any help thanks, i have searched and dont know if it will work.

The same model diypnp works for 90-05 miatas.
Wiring it up correctly is up to you.

what do u mean wireing it up,, i got the PNP , all i have to do is plug it in and run it. i am wondering if the 93 ca car needs a 93ca pnp computer or will the 91 work? the 93 CA car was sequential injected. it has 2 extra wires in the harness.

I'm in the same boat, actually. If I understand correctly I could use the optional sequential injection board for the DIYPNP if I want to keep the sequential injection - OR, I could just forget it and revert back to bank injection. Does it matter much? Nobody seems to think it does ... can anyone confirm either way?

DJ is there an option to run sequential injection on mega squirt? if there is where can i change the option so i can run it sequential?

Here ya go:

DIYPNP Sequential Injection Kit DIYAutoTune.com

But I'm not sure if it's really necessary...

The ECU connector is the same, and the only difference is the extra two injector wires. If you want to keep it simple, just parallel the 1/3 and 2/4 injector lines together. This is how the regular MSPnP (and all other MS1 installs) work for CA93 and 94+ cars.

You can add the sequential daughterboard and run four-channel if you want to, but you don't have to. I'd wager that most of us are still running two channel, regardless of year. The change to full sequential was mostly about idle emissions.

GOOD DEAL.. thanks for all the help i will have it done soon.

Thx for the reply Joe - so does this mean that any mods need to be made to the wiring pinout on the standard 90-93 DIYPNP? Or will it fire all four injectors with the standard pinout?

I don't know that I'd call it a "mod" per se, since with the DIYPnP you're free to wire it however you want. Just make sure that the Inj1 driver is wired to both 2U and 2Y, and that Inj2 is wired to 2V and 2Z.

Perfect - that's what I needed to know. Thanks a lot!
