Went to the track today and have a log file

[5.7ute]

Ok I must be a total tard here...I saved the new file and a copy of the old ones where you guys said and then went out and tried to find the PID in the scanner and a I can't figure out which one it is I need exactly to log boost.

In the calculated pid section it is called boost & vaccuum . CALC.BOOSTNVAC
You also need to log the SAE.MAP pid for it to work.
The best thing about calculated pids is you can add them to an old log file to view as long as that log file has the necessary pids logged. In this case any log with the SAE.MAP pid can have the boostnvac pid added.

In the scantool under the PIDs tab...

on the PIDs tab page, you can click on any of the column headings to sort on that column (click again to reverse the sort order).

WTF am I missing here. I went back and I still don't have it available...saved the pid.txt to desktop...opened mydocs/efi/v7.5/user config/saved the old and a new file....( I am looking at them saved in the box)

Opened the scanner/ went to PID's / looked for BOOSTnVAC and every iteration thereoff in the Parameters and the Descriptions and I still don't see it????? I think I seriously suck at life.

The file calc_pids.txt has to go in My Documents\EFILive\V7.5\User Configuration.

Also, under the PIDs tab, uncheck "Supported", then click once on the heading "Caption" to sort by the Caption column.

Here is a screenshot of how I have both of the files saved.....



Now I open the PID tabs and selected the actual boost pressure PID and get the red x...It said that I needed to select another PID GM.BOOST_DMA, but that PID is under the Diesel System Tab. What else am I missing now?

[joecar]

Close the scantool.

Save this calc_pids.txt file to My Documents\EFILive\V7.5\User Configuration.

Reopen the scantool.

Then under PIDs tab, click o the column "Parameter", and then select:
CALC.BOOST
GM.BARO
SAE.MAP

When done selecting, the CALC.BOOST pid should show valid (no red X thru it).

On CALC.BOOST, do rightclick->Imperial (to use psi as default).

On the chart, find an empty place (to the left or right of a chart), and do rightclick->Imperial Pids->CALC.BOOST.

Keep in mind when you are tuning with meth that the stoich is much lower than regular fuel, so if you are using a dual nozzle and pumping a lot in there, you will want to see AFR's lower then the norm.

It will depend on how much you are using percentage wise, but I have ran the best times between 10.5-11:1 with my dual nozzle alky.

Hope that helps, nice times from that ECS Paxton set up.

That's why it's best to use EQ units instead of AFR...

then when methanol is injected, you divide the appropriate AFR into the EQ value (you can have a second concurrent calc pid to do this for you);

I think (as an engineer) it is better if we all thought in terms of EQ...

One thing to note exploder is this pid is only as accurate as the info you give it. In the txt the equation is
CLC-00-008
psi 0.0 15.0 .2 "(({SAE.MAP.kPa})-101.3)/101.3*14.7"
The red amount should be your actual Barometric pressure. So if with key on engine off your map pressure is only 98 kpa you should change the equation to
CLC-00-008
psi 0.0 15.0 .2 "(({SAE.MAP.kPa})-98)/101.3*14.7"

What does the 101.3 mean and the 14.7 is afr??

[5.7ute]

101.3 is the kpa at sea level & 14.7 is the conversion to PSI.
