I want to turbo my 2003 SE over the winter. The first thing that I would like to do is replace the ECU and tune it so that the car run with the stock engine.

I decided to use a MS3X. I made a list of the stuff that I think that I need to buy, could someone have a look at it and tell me if I am missing something?

MegaSquirt-III w/PCB V3.0 - UnAssembled Kit with black case
MegaSquirt-III MS3X Expansion Card
DB37 male & female connector for MS3 and MS3X
A bunch of 1N4001 diode
GM Open Element IAT Sensor with Connector
Wideband

Thanks!
