Experienced Help with auto ve please

14.7 is reference to the fuel you are burning, ie gasoline.

you can also try to lesson the count that each cell must have to be considered. I do this on my higher boost cells as the street is tough to tune up high.

Using and lc1 wideband and a v2. Here is the tune file and most recent logs. There are a couple of dyno pulls and one trip to the race track thats about a 45 min trip of mixed driving.

Are these logs all from the same ctz file...?

[joecar]

1st log: PE ramps too slowly (and it is causing knock as load starts increasing).

other logs: no knock at all...!?

I thought i had p.e shut off an was just controlling fuel off the ve table. Im not around my computer with the software on it right now. And the tune that pasted is the latest tune in the car. The logs are not the same tune exactly from 12 to 13ect has small changes to the boost ve table. And the trip to track is the latest log.

[joecar]

If you have PE disabled, then you should not run up past medium load (not safe for engine to run it at load without PE)... so how do you tune it in this range...?

( VE calculates, airmass, PE specifies fuel ratio to go with that air... i.e. when VE is correct, you specify the fueling )

[RADustin]

for COS5, we don't need PE correct Joe? As B3647 will command richer? correct?

sorry to hijack.

I was under the same impression atleast thats how i read the tables description.

With a COS you can use either PE (B3618) or OLFA (B3647)(you ramp up EQR as MAP increases), or you can use both (richest table wins)... the COS is flexible this way;

and if you're running boost, you can set the PE MAP Threshold (B3613) to 105 kPa so that the PE table (B3618) now becomes the boost fueling table.

Im running in olsd. So is the pe still possible.

[joecar]

Yes, in OLSD, PE is possible if its enablers allow it to enable...

actually, in OLSD, the tables that are primarily active during normal running (i.e. no overheating or engine melting) are OLFA and PE (when PE enables)... the richest of the active tables (at the current operating cell in each table) determines the fueling EQR.
