I recently purchased the SSI-4 from Elliot at Turbosource in order to data log my fuel pressure. The unit was fairly inexpensive at $129 and really easy to setup.

I followed the instructional video awesomely laid out by Andy with Adaptronic:


Why would one want to data log their fuel/oil/meth pressure?

1. Engine safety (as pointed out in the video it enables some very nice fail safes to prevent engine failure)
2. Diagnosing any issues with your current setup
3. Remote Tuning!! (I have been sending my data logs to my local tuner for him to adjust my settings to reduce the cost of dyno times)

What is awesome is you can now buy the sensors needed for this unit from a well known shop Full Function Engineering for a very reasonable price of $60.

Here are some pics from my install:

 

Great stuff! I need to get some of those sensors from FFE I think!

 

So I have gotten some feed back and there appears to still be some confusions on installing the SSI-4. Here is a screen shot from Andy's video at 2:17 -



He shows how the wires will be coming out from the back of the plug.

A - Is the ground (Very important it needs to be connected to the -CH + the Chassis)
B - Is connected the Green 5V port on the SSI-4
C - Is connected to the +CH on the SSI-4

Since I currently only have 1 pressure sensor I made a jumper from the ground on the SSI-4 to the -Ch.

 

Thanks Shawn!

 

Does someone have recommended settings to start with for Fuel Pressure in the Power Cut tab?
