setting up ve table for vaccum and boost

Hello,

I am trying to setup the infinity tuner v2.96.8592 fuel ve table for map/ baro. This way i can tune this vehicle via vaccum and boost per rpm and load. I have tried many different setting in the infinity software and every different setting just shows values for kpa, tps etc. Below i have added some screenshots of the settings i currently have. 

Any help on this would be appreicated

Setup Wizard-->Basic Setup--

Setup Wizard-->Basic Setup-->Engine-->VE Table Load Axis Selection

Select "MAP/Baro"

I have already tried that but

I have already tried that but the load column for that is not displaying the values properly. i.e -17 -14 -10 -5 -1 0 2 5 6 8 10 15 20 25 30 40. only displaying 0-100 and the values look like the same ones when its set to kpa

MAP/Baro will be small values

MAP/Baro will be small values, nothing negative. It is a ratio of manifold pressure to atmospheric pressure and is typically only used for engines that operate in conditions where there are extreme elevation changes. For example, an engine at atmospheric pressure (0psig) would be operating at a value of 1.0 for a MAP/Baro VE table, less than 1 for instances of engine vacuum, greater than 1 for instances of boost. 

Are you sure MAP/Baro is what you are looking for? kPa is also representative of engine vacuum with values less than 101.3kPa (at sea level). You can also change the units to PSI by going to Wizards-->Units Preference and select U.S.

the reason why i am trying to

the reason why i am trying to set it up as vaccum and manifold pressure is because most of the cars i tune with the provided software use those values. I am not 100 % familiar with kpa vs load value i.e kpa vs boost/ vaccum conversions. So i am trying to elimiate any room for error. I was thinking maybe i was doing something wrong trying to set that part up. i went to wizards - unit conversion and the only thing that seems consistent is kpa on the ve map then going back into the wizard - engine and changing the ve fuel map setting to kpa. although there was one time i was just messing around with the software settings and i was able to get the ve to display the axis values i am confortable with.

that load axis looked something similar like this:

30.2

20

10

5

0

-5

-10

-12

-17

I didnt save the layout and have not been able to replicate that setting for the ve fuel map.

I think I get what you're

I think I get what you're trying to do now, you want positive pressure in psi and vacuum represented as in Hg. Unfortunately, you cannot represent vacuum as in Hg in the Infinity. You would either have it represented as kPa or psi. What you can do to help yourself visualize in Hg is to create a virtual channel that converts MAP (psig) to in Hg so you can see the unit in "in Hg" but the table axis will still be in negative psi.

Your VE table will still look like this, but you can open a text box to display the "in Hg" value:

Virtual Channel Text Box:

can you give me a description

can you give me a description on how to apply that to both the ve fuel map and the ignition map. i can live with it being setup as being solely psi for the the vaccum portion of those tables.

In the Setup Wizard, make

In the Setup Wizard, make sure to set the VE and Ignition Table load axis to MAP. From Wizards dropdown, select the Units Preference and select US. Conversely, you can change the units for each channel individually by double clicking on the unit associated with each. The channel units you want to set are "Engine Load." In there, you can select various units such as psi.

the things that you stated

the things that you stated above are not working correctly for me i have included a copy of my layout and you can just use a shelf evo 8 calibration. i tried adding a virtual channel with the formula from that screen shot that you posted above the software give me a error for it and there is now way that i can see to apply it to both the maps. Also under wizards - setup wizards- engine for the igntition and ve fuel map it doesnt give me a option to change it to psi.

the only options i have are:

Kpa/map

throttle %

mass air flow [---]

mass air flow [---]

map/epd

map/baro

DBW_app1 [%]filtered

under wizards-unit perferences- engine load. i have already selected psi still no change

Try this:

Try this:

Mitsubishi - EVO 8 v96.2_psi.itssn

kPa/MAP = psi when you have "Engine Load" units set to psi. I think you're getting hung up on the fact that it says kPa.

thanks that file you modded

thanks that file you modded for me displays it properly. how do i add the virtual text box to display in Hg?

Layout--->Add Virtual Channel

Layout--->Add Virtual Channel, then follow the steps outlined earlier:

What you can do to help yourself visualize in Hg is to create a virtual channel that converts MAP (psig) to in Hg so you can see the unit in "in Hg" 

Add a Text Box by right clicking in your layout and click "Text" then select the channel you created (in this instance "in Hg"):

Hey I'm having a similar

Hey guys I'm having a similar issue, didn't want to start a new thread cause figured it could be answered here and is related. I changed over my VE map to MAP/baro and the X and Y axis are correct as I wouod want them, however my map tracking still tracks in Alpha N By TPS. How can I get it to follow my map sensor rather then TPS for log tracking?

Thanks!

The InfinityTuner software

The InfinityTuner software only checks which table axis to use when it first opens a layout. After the first time you switch a table input axis, you'll need to re-open your layout for the live trace to follow the correct cells.  Also, the software won't automatically change the y-axis or x-axis breakpoints when you change the input, so if you're changing from MAP [kPa]  to MAP/Baro you will need to manually change the breakpoints in the table.  For instance,  breakpoints that were originally 60, 80, 100, 120 when using MAP [kPa]  need to be changed to 0.60 , 0.80, 1.00, 1.20  for MAP/Baro.  The relationship is a bit less simple to spell out if you started in MAP [psi],   but in general most engines will be around 0.20 - 0.70  at idle ,  1.00  at full throttle for a naturally aspirated engine (no boost), 2.00 is about 14-15psi boost, 3.00 is about 30psi boost. 

 

If you've already tried those things and you're still having problems, please take a log of the problem happening by moving the throttle with the key on (engine off) and attach the log (.itlog) and calibration (.itssn) file here.

 

Hope that helps,

SB
