Notes : - These OEM ECU connectors are no longer available to purchase new. Due to popular demand for this product though, we've created a trade in program where you must ship us a factory PCM with a good condition connector in order to build your new MSPNP Gen2 ECU. We will remove the connector from your factory PCM to build your new MSPNP2. Orders received without a proper trade-in will be refunded less a 7% administrative fee so please only place an order if you have a good condition ECU/Connector to send to us to use. You can place your order here on the website, and then follow these instructions: Customer_Instructions - MSPNP2-T8590 Customer Supplied Connector Program to send us your connector. We'll build your ECU to order and get it out to you fast!
- This one does not match the pinout for JDM 4AGE motors with factory MAP sensor, the 4A-GZE lineup, or later 20 valve engines.
- Although there is a paid upgrade to TunerStudio, it is not needed to tune this ECU. The free version included on the USB Stick can access all the features and tables of the MegaSquirtPNP. The paid version of TunerStudio simply adds tuning and analysis software, such as VE Analyzer Live to tune the fuel tables based on wideband O2 feedback (requiring a wideband O2 sensor and controller, sold separately). It also unlocks the ability to use customized dashboards, such as our MSPNP2 Dash, which is designed specifically to help make tuning your new build intuitive and easy!

Warranty Information - DIYAutoTune Un-Assembled Kits
Products purchased in kit form we will guarantee have all parts needed to complete the kit, and the parts will be in new and working condition when we ship them to you. If you find a discrepancy please notify us. We're pretty easy to work with and we'll do our best to take care of you quickly. Obviously we cannot warranty your assembly work of a kit. If you get stuck we suggest posting a thread at www.msefi.com or www.msextra.com and emailing us the link so we can attempt to chime in and working together with others we can usually help you get to the root of your problem. That being said most people don't have any problems assembling our kits, they are clearly labeled and go together just about as easy as any kit could.
Warranty Information - DIYAutoTune Assembled MegaSquirt ECUs and Accessories
This section applies to any product that is available as a kit, but that we also offer as an assembled product. Examples would be standard MegaSquirt I and II ECUs, Stimulators, and the like. Standard off-the-shelf MegaSquirt ECU Assembled units are covered by a one year limited warranty against manufacturers defects. Contact us if you believe you have an issue that should be covered under warranty. We will discuss the issue with you and provide an RMA number and an address to ship your unit to. Our tech will evaluate the unit and if a problem due to manufacturer defect is found we will repair it free of charge. We will cover the cost of shipping from our shop to you up to $25; we will need for you to cover any cost of shipping beyond $25 and the cost of shipping the unit from your location to our shop. If we determine that the problem was due to mis-use, mis-installation or improper modification, our shop rate will be $75/hr plus materials to repair your unit (one hour minimum).
We do not mind the modification of the unit as that's the spirit of the MegaSquirt project, just understand that if your mod appears to be the likely culprit of damage to the unit that we cannot support the unit under warranty. Note that extensive modification may complicate the troubleshooting process, and in some cases it may be neccesary to reverse modifications in order to return the unit to working order. Charges will apply for the time required, and in these case we cannot be responsible for putting custom modifications back in place after having to remove them to resolve a problem.
