Just in time for your summer project!
This reliable MSPNP MM9093 ECU was installed in my car in April 2009, and replaced last year with an upgraded unit. There was nothing wrong with this one, and the car was able to make good power in both normally aspirated (132RWHP) and forced induction (205RWHP) iterations. This has been sitting in my closet and now needs to go to a new home. I modified it to work with a variable throttle position sensor by removing a resistor (R6 - see second photo). It has firmware and tune to run my now supercharged car, so the tune will (likely) need to be changed before your use. The attached brackets allow it to be mounted in the OEM location and the DIN to RS232 tuning cable is included. I do not have the original disc, but updates and software is readily available from DIY Autotune. If you do not have an RS232 serial connector on your computer, you will need a USB adapter, and I recommend the one sold by DIY Autotune as others are known to not work.
