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:
And a diagram of the signal:
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:
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!
