3 bar map reading higher than the rest of the tables.

[jmac636]

I have exhausted all my options and I need help. I have been running a 3 bar OS for some time now. I changed setups and have to retune and in between setups I have tuned 1 bar setups no problem. All my other tables read say 50 kpa MAP and my histogram reads 145 or 155kpa. Key on Car not running the MAP voltage is 1.59 volts with a 3 bar map sensor from EFI Source.

1) I have went into the histogram settings and deleted the SAE MAP and SAE MAF like the directions tell you like post #16 here: http://www.hptuners.com/forum/showth...g-105-kpa-only

(This step for 2bar and 3bar enhancement only) Open VCM Scanner and connect to the vehicle. Open the Table display (Scan -> Table Display). Right-click the "Manifold Air Pressure (SAE)" PID and select "Delete". This removes the existing 1 bar PID from the table, if you don't do this the histogram will not function correctly.

(This step for 1/2/3 bar Speed Density enhancements only) Right-click the "Mass Air Flow(SAE)" PID and select "Delete". This removes the existing MAF PID, if you don't do this the histogram will not function correctly.

(This step for 2bar and 3bar enhancement only) Right-click again on the table display cell and select "Insert", go to the Engine -> Airflow section and choose either the "Manifold Air Pressure - 2 bar" or "Manifold Air Pressure - 3 bar" PID, double-click to insert it into the table.

2) I have even uninstalled and reinstalled the whole VCM Suite. I used an old beta version though from 2013.

Any suggestions are appreciated, Thanks.

Works fine for me, do you have a user defined boost pid or any other user defined pid that references map kpa?

I think that's the problem I will post back when I figure it out with details.

I removed the boost defined PID and now my logs look correct, Thanks RUSS!

I had added a Boost PID some one else had created and it made my logs all wacky. Even my old logs were out of sync with the Table KPA.
