OBD2 scanner

I have a cheapo £13 reader from ebay which allows me to read the fault codes, clear the fault codes and also read the vin of the vehicle, this type will tell you a general location of the fault i.e P0400 = EGR Valve

I then have a laptop with a licensed Ford OBD2 diagnostic software which cost £20, this allows me to do the same as my little hand held but also gives live data readings allowing further indepth diagnostics of whats causing the fault P0400 = EGR Valve = Recirculatory air flow not correct = clean the pipe work and the manifold with a decoking agent

I guess it all depends on what you want it for (y)
 
Where I could get that software? Well i ordered ELM327 - bluetooth thingy. It can also view live data readings, and in depth solutions... well, we will see... :)
 
If you've got an Android phone or tablet, get the Torque Pro app from the Play Store. It's good stuff ;)

So, i have obd2 tester, and it shows no errors :) also wanted to ask, what readings can you see? I miss fuel pressure in the rail and air mass... Can you see them in your software, and what software do you ise? Thanks,
 
Autoenginuity. As yes I can see all of the PID's there is no fuel pressure sensor on the cougar though. That tends to be more a diesel thing or if there is a returnless variable speed fuel system
 
Regarding fuel pressure in the rail - it is strange, because there is a sensor... also intake pressure...
Also one strange, or maybe maybe not thing: At idle my throttle position is 16,9% - ok. But on wot its only 84%. Why not 100%. We I played in my garage in neutral only, today will take her for a spin.
Also, how good are 0-100 and dyno features? Maybe someone tried? If so, what weight do You enter?

THanks,
 
I don't think there is a fuel pressure sensor, it would be redundant on this sort of system like Bob has pointed out; the regulator just maintains a constant rail pressure on a system like this. Useful for diagnostics but the ECU isn't concerned about rail pressure.

Intake pressure/vacuum relates to MAP sensors, this engine uses a MAF instead, different technologies but serve a similar purpose.

It may be your unit will list various sensors that do exist and just report nul values where the sensor isn't fitted.

Try an ECU reset, drive the car for a day and recheck the TPS readings that are returned to see if they change.
