Question on Auto Ve tuning

[MSGHUFF]

Followed the tutorial did the logging updated the VE but the tutorial just leaves you there... I am assuming I just make the adjustments to the VE tables and change everything back(connect the maf, enable mil's ect) right?

Is there a tutorial on how to tune the Maf, PE, and spark tables?

After doing VE table do this:

0. in OLSD tuing mode, log GM.DYNAIR to use to sanity check item 2. below or as a starting point for item 2.

1. re-enable PE table and set the AFR/EQ that you want, log with wideband and see if it agrees;

2. go back to OLSD tuning mode (no PE, no CL) and enable MAF, log MAFFREQ, AFR, WBO AFR, and do WBO AFR % correction procedure on MAF table (same as when you did it to VE table, except now your BEN map is X vs MAFFREQ where X is anything you logged (e.g. RPM 1 cell wide 0-8000));

3. go back to OLSD tuning mode and enable CL and see if trims are on 0%.

4. enable PE, CL, MAF and see what trims are and compare with wideband.

5. goto a Custom OS and transfer your tune over and/or tune some more.

Your running options:
a. OLSD (uses VE+OLFA)
b. CLSD (uses VE+trims)
c. OLSDPE (uses VE+OLFA+PE)
d. CLSDPE (uses VE+trims+PE)
e. OLMAF (uses VE+MAF+OLFA)
f. CLMAF (uses VE+MAF+trims)
g. OLMAFPE (uses VE+MAF+OLFA+PE)
h. CLMAFPE (uses VE+MAF+trims+PE)
i. some combination of above in COS.

The CL modes use the OLFA table whenever in OL.

newbie questions....

1. re-enable PE table and set the AFR/EQ that you want

going right from the OLSD tuning what table exactly do I re-enable? Just B3605 and 3618?

2. go back to OLSD tuning mode (no PE, no CL) and enable MAF

from the OLSD just enable c2901, 2902, 2903, 6002 and leave the rest the same?

3. go back to OLSD tuning mode and enable CL and see if trims are on 0%.

b4205 only?


Thanks

Set B3618 to the AFR or EQ that you want; leave B3605 the same as for OLSD tuning (you can fine tune your non-PE AFR in B3605).


2. go back to OLSD tuning mode (no PE, no CL) and enable MAF

from the OLSD just enable c2901, 2902, 2903, 6002 and leave the rest the same?

Yes, correct.


3. go back to OLSD tuning mode and enable CL and see if trims are on 0%.

B4205 and B3801.
