  • There’s more than we could list here– click this link to view the full feature list of MS2/E.
  • Also- you can click this link for the official DIYPNP Product Page Feature List which includes the above list plus a hardware level feature list (that tells you not just what you can do, but what hardware is available to do it)

Note:  Some of the features listed above use the General Purpose Inputs/Outputs.

This one fits early TPI Camaros, Corvettes, and Firebirds, many TBI V8s, V6 Fieros, and many more. See the Models page for a detailed list of known applications and how to wire up the ones we have tested in house.

This board supports up to four BIP373 ignition drivers which are not included in order to keep your cost down since most of you won’t need them for running your stock setup. If your application does require internal ignition drivers (again, most do not) you can add BIP373 ignition drivers to your kit.  We offer a DIYPNP BIP373 mod-kit which includes the BIP373, Heatsink, and mounting hardware here.

  1. 4 out of 5

    DIYPNP Delphi-56I just installed one of these in my Pontiac Fiero with a Chevy 3.4 liter V6. Generally speaking, I'm pretty happy with the results. I still haven't finished the tuning, but it runs and drives. However, some of the documentation (specifically regarding the stepper idle control and DIS) left a bit to be desired. But I was able to figure it out. I also bought the TunerStudio upgrade, to make use of the auto-tune feature. That should make the fine-tuning a lot easier.

    Diypnp Delphi 56Never assembled a computer before but we'll labeled. It would probably be easier if I were putting this in a Chevy but I'm putting it in a air cooled 4 cylinder vw that was previously fuel injected with a Chevy computer. Soldering is not hard but does require alot of reading and double checking. So far I have no complaints but I still don't have it up and running yet.

How is the DIYPNP different from an MSPNP, besides being a solder it yourself kit?

  • The DIYPNP and MSPN Gen 2 are closely related. Both use the MicroSquirt Module at their core and run MS2/Extra firmware. The MSPNP adds a couple extras – an improved knock circuit, peak and hold injector drivers, and a 4 bar MAP sensor with a 1 bar barometric correction sensor. Other than that, they are very similar.

Can I use an MSPNP map in a DIYPNP?

  • Yes, but you will get a couple warnings when it loads as some of the output pins have different names (and the outputs may also be on different pins depending on how you built the DIYPNP). You will need to confirm that the outputs are on the right pins before you attempt to start the engine.

Can I use a Stimulator or JimStim with a DIYPNP?

  • This is fairly difficult – you will need to make an adapter harness with the same pinout you have built for the DIYPNP. You can, however, power the DIYPNP directly from a 12V power supply for loading firmware and other bench tests.

Can this fit in the stock ECU location?

  • The DIYPNP is taller than a stock ECU. We have confirmed it won’t mount to the factory kick panel bracket in Fox body Mustangs. Fitment in other applications is uncomfirmed.

Can I buy a fully assembled DIYPNP?

  • DIYPNPs are only sold in kit form, but we may have a ready to run plug and play option for your vehicle in the MSPNP line. Please see our line of pro and PNP options to determine if we have one for your car.

    This DIYPNP supports all full size TBI trucks from 1988 to 1992, and 1993-1995 manual transmission trucks as well. The 1993 and later automatics were computer controlled and used a different connector. But for 1990, the DIYPNP supports both manual and automatic equipped trucks.
