With all the different MegaSquirt options out there, chosing the right system can be a bit intimidating. The first decision you’ll need to make is the overall approach. Do you want to keep expenses as low as possible by soldering your own kit together? Or would you rather spend less time and more money? Here’s a comparison of the different approaches you can take.
| Unassembled Kits | Assembled MegaSquirt * | DIYPNP | MSPNP | |
| About how much does it usually cost? ** | $250-$375 | $305-$640 | $460 | $700-$1700 |
| What does it fit? | As a universal system, it can be adapted to most cars except diesels and direct injected engines. | As a universal system, it can be adapted to most cars except diesels and direct injected engines. | The DIYPNP can be adapted to most cars that use the ECU connector included with the kit. | MSPNPS are model specific and cover a wide variety of vehicles. |
| How much work is it to build? | The ECU will need to be soldered together. Plan on around 8 to 10 hours if you are inexperienced at soldering. Any surface mount components will be preinstalled. | Depending on your application, an off the shelf MegaSquirt may need minor modifications before it’s ready to install. Contact us if you would like one with special mods already installed. | Simplified assembly means that a DIYPNP can be assembled in less than half the time as a regular MegaSquirt. All surface mount components are already installed on the MicroSquirt Module. | No modification or assembly is required – the MSPNP is ready to run, right out of the box. |
| How much work is it to install? | The wiring harness has a MegaSquirt connector on one end and the other end unconnected. You will need to add the other connectors needed to the wiring harness to complete the installation. | The wiring harness has a MegaSquirt connector on one end and the other end unconnected.

* MicroSquirt falls into this category, however it is not easily modified, nor does it require modifications.
** This price range includes ECU base price, Stimulator if applicable, and standard wiring harness if applicable. Rounded to nearest $5.
