plugged tube. dirty/faulty sensor. the three should read within .5-1.5 psi of each other at KOEO.

 

Here we go....both MAP & EBP are way low. This is koeo. How do I fix this? Thanks!

 

The Baro is perfectly normal but with both MAP and EBP reading so close that's almost like a PID thing. Is there a way to change the PID values or more than one value that you can use?

 

Maybe double check with another device to verify. Or maybe a Torque Pro guru might see this thread.

 

What are the formulas for ebp & map for the Scangauge? I can use it to verify.

 

EBP
Exhaust Back Pressure
07E0221445
046285140645
3010
001D00500000
EBP

Yea, MAP is a standard gauge - but this XGauge is actually better than the standard one. It has a larger range which was needed because the standard gauge tops out around 37 psi absolute (about 22 lbs of boost), which diesels have no problem doing. This one should read well beyond 22lbs of boost.

Manifold Absolute Pressure
TXD: 07E0221440
RXF: 046285140640
RXD: 3010
MTH: 012203200000
NAM: PSI

With a little tweaking you can adjust this to read boost as you said.

To do this, just plug in the MAP code - get a reading from it with the key in the on position but the engine off, then based on the reading changed the last 4 digits of the MTH to whatever corresponds to your reading on this table

14.0 -- FF74
14.1 -- FF73
14.2 -- FF72
14.3 -- FF71
14.4 -- FF70
14.5 -- FF6F
14.6 -- FF6E
14.7 -- FF6D
14.8 -- FF6C
14.9 -- FF6B
15.0 -- FF6A

So, for example if you got a reading of 14.5 PSI with key on engine off you'd change the MTH to 01220320FF6F and the reading should read 0.0 with key on engine off and would then show how many lbs of boost you were at when the vehicle is running.

 

Thanks Rusty.

Anyone considering one of these, I have my Samsung tab3 7" tablet with Otterbox case mounted to the windshield with a Ram Mount Tablet holder that I bought from Amazon. The mount is rock solid.

 

I haven't programed the SG for ebp or map yet.

Does anyone else have this problem....initial start, Torque Pro works great and all gauges work. I stop at the store, turn off truck, come back and restart and I get this.....it happens everytime.

 

OK, I just checked my MAP & EBP with the Scangauge. I got....

MAP 14.7

EBP 15.0

So I'm good. Apparently the formula in Torque Pro needs tweaked.
