Just installed Scangauge & set up coolant & oil temps. Decided to add 2 more gauges & used Boost & HP. When running truck with heavy load (26000) I noticed that the boost gauge would go negative & the HP gauge would drop considerably. In a little time it would go back normal. I used the values for 6.0 & Ford specific tables.

Does anyone have an idea what is going on?

Do you mean under Hard Acceleration Boost would go negative??

check this thread out Boost may take a little playing with to dial in

lots of good stuff n there^^^^^^^^^^^^^^^

 

Boost
TXD-07E0221440
RXF-046285140640
RXD-3010
MTH-001D0050XXXX



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.

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
12.7 FF81
12.8 FF80
12.9 FF7F
13.0 FF7E
13.1 FF7D
13.2 FF7C
13.3 FF7B
13.4 FF7A
13.5 FF79
13.6 FF78
13.7 FF77
13.8 FF76
13.9 FF75


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.



 

Also, check which version you have. If it is 6.0, it will read pending codes.

Go to their website and read up.

Upgrade : Linear Logic - Home of the ScanGauge

User Manuals : Linear Logic - Home of the ScanGauge click on version 6.0 User manual.

 

That worked. We're cooking with gas now. Thanks for your help.

I tried the fuel level x gauge and it doesnt work, any suggestions?

 

I used that one once just to see if it worked, and it did. All I can suggest is triple check your entry.

I was testing 2 boost gauges just the other day and one didn't work. Checked and well, I missed a number.
