Experienced Help with auto ve please

[johnj]

So i have been trying to get my auto ve to work for a little while now. It seems like when ever i convert my map with multipliers pretty much everything is gone and hardly any change is made to my ve table. Here is my pid selections am i missing something or does my ve table have to be in lambda? Thanks in advance. 1841718417

Post some screenshots.

Do you have FlashScan V1 or V2...?

Your wideband is an LC-1...?

[joecar]

Post log files and current tune file.

[johnj]

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. 18425184261842718428

[johnj]

There is an a and a b map in the log a is out of boost b is in boost.

[RADustin]

try to make one map with the entire map spectrum. Then split it up when you paste it back in. This worked best for me.

[johnj]

Ok I wil give that a go see if that helps me out. Can any one confirm for me weather or not the tune needs to be in lambda or if its ok to be in stoich???

[RADustin]

I tune in lambda.

are you tuning to 14.7-stoich? if so it shouldn't matter. If anything else it would matter I believe.


edit- I tune in eq. (inverse lambda) this is how Joe set me up lol. worked perfectly(thanks Joe!)

[johnj]

Yes 14.7 on the high side and I believe 11.5 low side

[RADustin]

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.

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...!?

[johnj]

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.

[johnj]

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

[joecar]

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

sorry to hijack.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.

[johnj]

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.

[RADustin]

in comparing my B3647 100 kpa column to my PE table (B3618)- the PE is slightly richer(stock ls1 PE table).

I have my VE dailed in- so I supposed I could enable back PE mode- I am curious at why PE is safer.

Right now I command a max of 12.5AFR(1.17 eq) in 3647- should I re enable PE mode (B3618) and set it to match the last column in B3647? This way I am 'guaranteed' to get the enrichment?

...very interesting.

[RADustin]

John,

Your VE looks very choppy.

I would ensure everything is setup in EQ ratio and go from there. Start by smoothing out the VE table by hand a little bit- then go take some good logs. How is your wideband setup? Is your filters set correctly in the maps? When I go to your map properties it has a 0 entered for cell count for considered empty. This should be 10-50 IMO. Also- the data you have is very sporadic- I think your WBO2 or it's setup is faulty. Post your calc_pids file.


Your high and low base spark tables should match base spark in gear and park neutral in the idle regions. I set 0.08-0.32 g/cylinder and 400-1200 rpm all the same- what I want my base timing to be( I run 26°).

Your end timing looks real low- I run a final time of around 22° in the high/low maps, then use A0010 to subtract ~1° per pound of boost. It works well. I also have a 5.7- your 5.3 I believe should be fine with more timing, but that's your gamble. I know 4.8s love timing.

[johnj]

My wide band is set like 12 inches from the turbo outlet. I adjusted my cell count last night to 50 before i went and did about an hr or so of some driving and i got some pretty good results i think. Ill post the log file tonight when i get off work. Im going to try to get some dyno time this week end and see if can get some more logging in.
