Re: Adding boost pressure sensor to my install

I installed the boost sensor today, and I am getting readings. They are a bit wobbly, but with some adjustments I managed to get some readings. I adjusted the AFR values, and ended up with a=25.90 b=-12.90. That gave me some sensible readings from 0-4.4 psi. Does these numbers seem sensible to you? ...

Re: Adding boost pressure sensor to my install

So basically if I copy the values from the pressure readings, I can read out pressure in PSI with the AFR variable? Thats a great idea! Thank you so much! The easiest install for me will be to drill and tap a 1/8" npt hole in the upper intake manifold. I have seen similar pressure sensors befor...

Adding boost pressure sensor to my install

Hi! I have a couple of question about boost pressure sensors. I have a spare of the oil and fuel pressure sensors. Is there any reason why I couldn't´t use it to measure boost pressure? Also - at the moment, I´ve used all the pressure reading inputs - is there a trick to add another one, or would th...

Re: Bouncing fuel pressure sensor

Again I have to say that this is really amazing customer service! So cool!! :D I installed the new firmware and software today and played around with the numbers. Started with 800ms average (40 samples) which was dead steady, and after driving around and changing it a bit I settled for the 600ms ave...

Re: Bouncing fuel pressure sensor

That is very kind of you to offer! At the moment, I am able to read the pressures, and it´s good to know that the readings from the gauges are the same. It would perhaps be more interesting to see how the readings would be with 0.6s averaging for all the inputs if you don´t mind? Thank you so much a...

Re: Bouncing fuel pressure sensor

Uploaded the new software today before going out on a longer drive. It works wonderful! It´s still rather bouncy on the gauge closest to the injection pump - I suppose the demand from the IP is quite fluctuating - but now it´s readable and understandable, so I´m very happy with the update! Thank you...

Re: Bouncing fuel pressure sensor

Ah, yes, I forgot to mention that! The "oil pressure" is pre filter on the wvo side, "boost pressure" is pre filter on the diesel side, and "fuel pressure" is common just before the injection pump. In the video, the car is idling on diesel, so there is no lift pump runn...

Re: Bouncing fuel pressure sensor

Haha, keep the questions coming! :) :) Yes - all the readings are bouncing. The pressure sensor closest to the injection pump is bouncing quite a bit more than the sensor closer to the lift pump. It seems like the filters are acting like "buffers" and is taking away some of the pressure sp...

Re: Bouncing fuel pressure sensor

Wow, if you can do that, it would be really cool! :) To be honest, I don´t really know what would be the "perfect" average. It is good to be able to see the fuel drop when I accelerate, but it seems to me like I am reading quite a bit of the pulses from the lift pump. Maybe cut it in half ...
