Project Page for NP Complete Performance Hello, We are looking to develop a plug-and-play VEMS kit for the Dodge Neon SRT-4. http://www.allpar.com/neon/neon-srt-4.html I believe the only difficult part will be the crank trigger. Our crank wheel is a bit strange. It is a 36 tooth wheel, with 2 fused teeth and 2 missing teeth. Here is a picture: http://www.northtexasneons.org/~antihero/pics/ngc_wheel.jpg And a diagram of the signal: http://www.northtexasneons.org/~antihero/pics/ngc_4cyl3.jpg The sensor is a hall effect sensor, so you get a very nice and clean 5V logic signal out of it. Other details about the motor: 2.4L DOHC Turbocharged - Stock turbo - Mitsubishi TD04 - Mopar S3 upgrade - Mitsubishi TD05 - However, many people are running other, much bigger turbos Stock sensors: 2.5 bar MAP or 3 bar MAP with Stage 3 kit (will probably use VEMS internal MAP sensor) 2.5 bar or 3 bar TIP sensor Knock sensor Cam position sensor (not sure if we will use this or not) IAT - located right before throttle body in cold side pipe AAT - located at air inlet Usual coolant temp sensor, etc Ignition - 2 coil, waste spark ignition O2 - 2 stock narrowband O2 sensors, but we'll use the VEMS wbO2 Fuel - varies. There are many different fuel system configurations people are running, including RRFPR. We would minimally want to support 4 injectors in both hi-z and low-z form, plus a spare injector for W/I. There has been recent work to get Megasquirt running on this car with some success. They have added some code to support our crank trigger. I would like to duplicate this work with VEMS so we can start using VEMS as well. Here is the wiring diagram they have used for setting up Megasquirt: http://megasquirt.sourceforge.net/extra/pix/msneonwiring.gif My first priority is figuring out what I need to buy to setup a test car. After that, figuring out the crank trigger. If anyone has any suggestions on anything, please feel free to chime in. Sorry that this page isn't formatted very well. I will work on that. I am new to Wiki. Thanks!
