What table "xxxxx" is the command afr for what map pressure
What table "xxxxx" is the command afr for what map pressure
Commanded EQR:
- OL: B3605 or B3647 for COS.
- PE: B3618.
Do use EQR rather than AFR (set tunetool fuel units to EQR), you will find it easier...
CL will be EQR 1.00, and PE should be EQR 1.17 for NA, and EQR 1.25 for boost (regardless of the fuel you run)
( you view the tunetool tables in EQR, you log EQR and/or Lambda from wideband )
( you do have to set the stoich AFR in table B3601 )
( for example, stoich AFR's: gasoline 14.7, E10 14.2, E85 9.6 )
The truck in working on doesn't go into PE like it should. It stays in CL under WOT and removes fuel under boost when the whipple ecm is adding fuel. I've got another thread somewhere with the tune posted and data logging file if you would be up for examining it for me ?
Post your tune file/log files.
Point me to your other thread...
using this method, if the car will be open loop, i need to modify the CALC.PIDS as said above. wich one will be the input data to correect the maf? and wich one will be the input data to calculate the VE MAP
If you're running OL (no CL) you'll be using WO2BEN only (no LTFTBEN)...
so you must edit calc_pids.txt as follows:
change CLC-00-200 from this:
to this (see the red zero):*CLC-00-220
factor 0.5 1.5 .4 "iff({CALC.CL}, {CALC.LTFTBEN}, {CALC.WO2BEN})"
( This forces CALC.SELBEN to always use CALC.WO2BEN for corrections. )*CLC-00-220
factor 0.5 1.5 .4 "iff(0, {CALC.LTFTBEN}, {CALC.WO2BEN})"
Use Notepad to make the edit (when you exit Notepad click Yes to save the changes).
You now proceed as said in post #1 (use CALC.SELBEN map to correct MAF, use CALC.VET map to make a new VE).
When doing this tuning I have followed all procedures and Im getting corrected MAF and VE table as expected. The only thing that is throwing me off is how choppy my AFRs are looking while logging. Im assuming this is because I'm doing CL tuning using this method. The up and down swings correlate perfectly to the switching of the O2 sensors. Would it be better to do this tuning using OL so that fueling isnt so choppy? Or is it a function of the wideband I'm using (AEM analog)? Or does it not matter as it is averaging out over time?
Post some log files.
LTFT's are a filtered from STFT which are filtered from NBO2 swings (i.e. they should not look choppy).
