Trouble With CalcVET

[SLP IROC-Z]

I finally finished setting up calcvet and calibrating my FS2 to my lm1 wbo2. I setup an OL speed density tune and did some data logging, i set the tune up rich for obvious reasons but after starting to build a new VE table my car leaned out more and more. eventually i called it quits because it was hitting 17:1 barely accelerating . Being the newb i am i decided to post here for help. here is my calculated VE table and log file. Any help is greatly appreciated.

Log_0011.efi
calc_pids.txt

Edit: I just changed part of the calc pids to "{GM.EQIVRATIO}*{EXT.WO2LC11}/14.7" from "{GM.EQIVRATIO}*{EXT.WO2LAM1}" when i was data logging. was that the issue??

You want to build a map of CALC.VET not CALC.VEN...

but the map you show of CALC.VEN contains bad data (it is low by a factor of 10).

[joecar]

You really should connect your LM-1 to your V2 using a serial comms cable (with a null modem adapter), and avoid the analog interface.

[joecar]

Your log shows 25 pid channels, this halves the data sample rate, you want the most data for tuning... remove a pid (e.g. remove these: LONGFTAVG1, LONGFTAVG2).

Something is going on with your MAF in the range 5500-6525 Hz... post a pic of the MAF table you're starting from.

Your PE is commanding lean at any load <-- this is BAD

(looks like your tunetool has swapped Lambda/EQR units)...

in tunetool, go Edit>Properties and set fueling units to EQR, exit tunetool and reopen it,

then go and fix B3618 PE table and B3605 and/or B3647 OLFA table (at load you want to command EQR 1.165)...

remember to save file.


edit: correction.

Also, your DAT is high... from where are you getting air into the MAF...?

[joecar]

ALSO: your MAF is failed (MAF DTC is present)... this means you cannot do Calc.VET


with MAF disabled you should be doing Calc.MAFT

If you want to do Calc.VET (you should, at least initially) the enable the MAF.

Im going to leave the wideband the way it is for now so atleast i can figure out how to get this to work then ill worry about making it perfect.

ill remove unneccesary pids.

its a stock maf table for a zo6 vette (85mm maf)

ok, ill check that

this is because the tune is setup SD

So should i do Calc.MAFT or Calc.VET? Im thinking about doing away with the maf all together.

There is no calc.pe pid on my pids list

I do not have an extra bung for my Wbo2 so the pass side o2 is removed, obviously i cant do a CL datalog that way so is there any other options
