Calc.VET: correcting MAF and calculating VE (in single log)

[TunasTwins]

Im ready now.

Can you test the ACP signal by connecting 1 or 2 AA batteries to it, and see if the scantool logs the correct voltage for the pid GM.ACP.

[joecar]

Is your LM-1 programmed to default AFR:V function, or did you program it the same as the LC-1 (use LM Programmer to view the AFR:V function graph)...?

[joecar]

If you can read GM.ACP.V and your LM-1 is programmed to default, here is the calc_pids.txt to read your LM-1 analog voltage thru the ACP input (air conditioner pressure)...



this calc_pids.txt uses your LM-1 wideband analog output (read into the AC pressure sensor circuit) to calculate wideband lambda and WO2BEN...

so it uses both WO2BEN and LTFTBEN (i.e. SELBEN selects whichever one is appropriate based on CL or not CL).

[joecar]

You will have to select the pids CALC.WIDEBAND and GM.ACP.

My work week starts today. I will do the testing next Wednesday. I got the green light to purchase a V2 but would still like to see this to the end. My next project will be to make a harness to quickly replace a nbo2 with the wbo2 and keep closed loop functionality. I see a trip to the junk yard in my near future. Also, my lm1 works great yet I am looking into the 14.7 pure plus. Ground offset will be the decid8ng factor. Im trying to create a system that will aloow me to quickly hook up to to various vehicles f9r street tuning.

I wired my LC-1 to an NBO2 plug that I cut off an old NBO2 (so that the LC-1 gets power/ground from harness, provides NB signal to harness, provides WB analog and serial signals on loose wire that is feed thru transmission lever grommet into passenger compartment)...

you have to be careful: some vehicles switch the NBO2 power/ground on/off while driving (for example GTO does this)... you have to check a wiring diagram for your year/model/vehicle (make sure that NBO2 power and ground do not go thru PCM).

[joecar]

When you do get your V2, you can use the calc_pids.txt that is provided in post #1 of the Calc.VET thread.

Josh,

Check that you can log the pid GM.DYNAIRTMP_DMA...

if you can't (your OS does not support it) then we can edit your calc_pids.txt to use table B4901 from your tune to calculate dynamic air temperature (CALC.DAT).


[ when using V2, there is a B4901 modified calc_pids.txt in post #1 of the Calc.VET thread ]

[joecar]

lol, that would be post #1 of this thread.
