I am tuning a vehicle with a WB and the ve table doesnt seem to move 1:1 more like 2:1 is anyone else seeing this trend or is it just me.

Just move it till it reaches what you need it to be. How hard is that?

1:1 or 2:1 compared to what? I am seeing that the trims are very particular when you are narrowing it down. Are you planning on disabling closed loop? I wouldn't tune with wideband if you aren't.

open loop tune. It usually take two passes accross the table for the fuel to fall into line

11:1to 13:1 seems like it takes 36% instead of 16% reduction in the ve table

Another_User

You need to watch your other tables. VE is not the only table affecting your fueling, especially in open loop. Did you make the entire AF vs. ECT 1s? So many tables, so little time...

yes that table is set to 1.13 all the way accorss commanding 13:1. This way i divind the actual/commanded and find the percentage that is off and then scale accordingly

Are you tuning mafless still?

Yup. This is a customers car and the maf is unplugged until i get a clean ve table

I have a question, when you say it "16% reduction" does that mean subtracting 16% or multiplying by .84?

HumpinSS

multiplying by .84

P Mack

Well the only other thing i can think of is your wideband is off.

What if two different people using different equipment get the same results?

Open Loop with the MAF - about 2.5- 2:1 change in VE.

I think it goes back to gameovers posted "Airflow Calc Thread". Closed loop - Through the O2 sensors is a different ballgame. FWIW.

Pull the fuses ( takes about 60 secs) to zero out the "Long Term Idle Trim Airflow" .

You're welcome. It's so nice when the young guns treat the old farts well .
