I should put that one on the Torque PID page. Great job! I never thought of that one, and I haven't even had the time to tinker.

Now... the EBP will be reading high by 2 - 3 PSI, and that makes sense. EBP shot.

I wish that made sense...

I have tested 2 OEM and 2 after market and the all read 14.2 ish. I pulled the new EBP sensor this am and tested it uninstalled and it read 14.2. Unplugged from the pigtail it read 43.5 .

That's why I'm curious as to what other than the PCM could influence 4 different sensors to read that high?

To remove the sensor from the equation, could you test the same sensor on another truck? If the reading is correct on the other truck, seems like it's time to start working backward through the wiring on yours...

Does this use the vehicle baro sensor?

Yes, exactly. It uses the pcm baro reading instead of the baro sensor on the android device for the calculation.

First thanks to all for the responses. The moral of the story is OEM Sensors..... I'm absolutely a convert! Turns out my OEM was bad followed by to bad Borg Warners.
Thanks to Pony Boy for doing a sensor swap with me and it proved out Tuglys thought, I was over thinking it. DOH!!!!
Power is better, flutter reduced, seems to downshift better. Proved out by hauling a bobcat and a dump trailer today. Much more fun than a gutless rug.
Pika your boost calc is working great!
Again thanks.

I'm sorry for bringing this thread back up and hi-jacking it but ,

these are the readings I'm getting from Torque-Pro

KOEO

MAP - 12.3
EBP - 16.4
BARO - 14.5
BOOST - -2.2

If I understand from all the reading that I have been doing with trying to understand my truck with Torque Pro ,

I would say that I have to replace my EBP sensor . It was cleaned and the tube was cleaned about a month and a half ago .

Anybody have any thoughts on it ???

Thank-you .

Check this first:

MAP , EBP & Baro should be within .2-.3 psi of each other on a cold engine with key on engine off (KOEO)

If they are all different, verify your Baro reading to standard pressure at your altitude/elevation

Verify the BARO reading with the latest formula here: [LINK]

Check your MAP formula, check your EBP formula, all three of the readings should match, as Rich said.

I have checked , then re-checked and then triple checked my formulas with what has been posted and updated from the PID listing that Rich has put together .

I still come up with the same readings ;

MAP 12.2
EBP 16.2
BARO 14.4
Boost -2.2

I will still keep playing with this until I get it figured out .
