Re: Diesel injection effects on fuel rail pressure sensor

Well Taho, you were not wrong when you said "good luck". I have been trying to power a fuel rail pressure sensor on a donor vehicle using a stable 5V supply and earth independent of the ECM to retest the theory. This is not my concern as this is reasonably easy, my concern has been trying to convinc...

Re: Diesel injection effects on fuel rail pressure sensor

Many thanks Taho for your input, it really does help. I will try to carry out the same tests over the next week or so using a separate power supply and earth independent of the vehicle at the fuel rail pressure sensor. I will then retest and view the effects on the fuel rail pressure sensor output a...

Re: Diesel injection effects on fuel rail pressure sensor

So Sorry I have taken so long to follow up this quest but it’s been a little busy (No excuses I know) To cut a long story short regarding the effects on common rail pressure and Diesel injector operation, I have carried out 2 tests, the first of which on a 2007 BMW 318d. The plan was to look at the ...

Re: New forum Member

Hi Debbie and thanks for the data you sent, sorry I have not responded sooner. Looking at the data it is very strange to see that every alternate cylinder reports low efficiency which indicates one bank of cylinders, given this vehicle is equipped with a flat plane crankshaft. If you “right click” o...

Re: Distributor syncrograph

Hi Debbie and thank you for your post. To be perfectly honest I had to Google Syncrograph and can now see how this device determines the stability of a conventional distributor at various speeds to conclude good even dwell with mechanical and vacuum advance. In answer to your question I would like y...

Re: Hello

Hi Mark and welcome. Regarding the patterns you have captured could you upload them here so I can take a look at the settings etc. of your scope, along with a brief description of what circuits were under test? There are numerous reasons why some traces may have this "haze" or "noise" present along ...

Re: [X300] Mystery....

Here is a theory going on a bomb that was dropped early in this discussion. The vehicle had been gas converted and now reversed? This really does move the goal posts. From a pure mechanical view, how many miles have been covered using LPG? My experience with LPG results in rapid valve seat wear and ...

Hi Debbie from Steve Smith at Pico and welcome. Well, you have arrived with a bang and now I have my work cut out. First of all thank you for posting this information which I will look into and feedback as soon as possible. One question regarding the relative compression test, once the engine was di...
