Well I am pretty upset that the livewire ts does not read ebp (exhaust back pressure)... it seems so simple for the livewire to do it, the truck is already set up for everything. At first the livewire could read ebp but the equation was wrong. Then with all the complaints they got... instead of fixing the equation they got rid of it all together, so if you update or have a new livewire ts it does not even have the ebp pid.
I am determined to figure out how to make it work and I have a couple of different ideas... but I have a few questions and I need a little help from some electronic gurus here on the org (electronics are not my specialty
As far as I understand it the ebp sensor is a 5 volt sensor. It reads from 0-5 volts which is a linear equation to equal 0-54psi... So I should be able to tie into the lines, and plug it into the livewire TS, select the firewire cable, select or make the correct formula, and bam I get my ebp sensor back.
Here are my naive electronic questions:
- Will tying into the ebp wires disrupt or mess with the computer signals
- what equation should i choose?
- what are the 3 wires going to the ebp sensor (?ground, signal, 5v power?)
- is there an easier way than what I am doing
Here is some good info from the 6.0 bible
On a side note if I can get this to work then I should be able to do the same thing with the boost side of things so I can read it correctly past 30psi
