Tuning Open Loop EQ Ratio

**1slowbusa** · 06-13-2013, 04:09 AM

I am a little confused on tuning the open loop EQ ratio.

Do I need to set the EQ Ratio to 1 and tune the AFR to Stoich and after that, how do I determine what to set the Open Loop EQ Ratio at? This is what I am confused on.

Or

Do I just add 10% to the entire table from stock?

If I am out in left field with this procedure, please let me know.

The car starts fine and it idles fine, just need to get rid of the lean condition while warming up. BTW, I have the 1 bar speed density with RTT if this will make it easier to tune the cold start. If more information is needed, please let me know.

2000 Camaro SS LS1 M6, AFR 205 heads, Polluter V2, headers, catted Y Pipe, Fast 102 Intake with NW 102 Throttle body, FTP 102 Lid.

I just turn it on and listen to it.

I'll have to look at mine and see what I set it at. I run an SD tune in open loop all the time. So I set the EQ ratio to a target AFR that I wanted and used the wide band to log % error and corrected from there.

I didn't know the radio did all that stuff. Whatever it is.
