Product Description

MegaSquirtPNP Gen2 – Plug-N-Play Standalone Engine Management System

Fits the following cars with the 3S-GTE engine:
1990-1991 Toyota Celica All-Trac (GT-Four) with manual transmission
1991-1992 Toyota MR2 Turbo with manual transmission

These are for USDM pinouts; the pinouts we’ve found for the 1990-1992 JDM MR2 Turbo look identical. We have not tested this MSPNP on a JDM car, but from all indications it should work. Some markets used different ways to number the model years. See the ECU part number listing at the end of this entry to check if a Toyota ECU not sold in the United States or Canada is compatible.

Second Generation MSPNP; Easy to Use and Install!  

MegaSquirtPNP Model #TS9092 Features:

• Fully Plug and Play Installation – No wiring required for basic functionality, other than adding an IAT sensor (included in the package).  Install time is about an hour, only exception is if you need to have someone weld in your IAT sensor’s bung for you real quick.  That’ll cost you just a few bucks at most tuner or welding shops.

Note: 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).
