VE Table Smoothing Question

[Chalky]

Working on my VE tune and am making progress. Question is: When is it appropriate to use smoothing for the whole table?

I was making progress in getting the table in order and decided to do a complete VE table smoothing and it seemed to make things worse. My take on the matter is that I should just focus on the spikes and variances in the table vs. making the whole table flow more smoothly.

[joecar]

Don't smooth.

Don't smooth.

Chicken :muahaha:

I have a beautiful looking VE table and pretty sexy BENs as well ;)

Generally you don't want to smooth the whole table because it will pull all the cells either up or down.

When I do "local" smoothing I find my BENs creeping away from 1.00...

I have [a yet unproven] theory that the spikes are due to resonances or harmonics... they keep coming back in the exact same cells. ;)

Andrew, do you have any "guidelines" (...a tutorial...) on how to smooth...?

Speaking of theories, let me ask you this:

SinisterSS was looking at one of my log files while tuning in SD and noticed a lean spike. Car was being accelerated and AFR went real lean for a moment and then climbed back to normal AFR. Car did not have any KR. Could this have been an anomoly?

[joecar]

Would you be able to post a screenshot showing this spike (show enough PIDs, and zoom in some)... time to learn how to post screenshots... :D

I have seen lean spikes in actual AFR without any detected knock, I am wondering if it is misfire related (O2 reading won't be correct because fuel is raw/unburnt, I'm wondering if it ignites in the header).

[Chalky]

Here is the info I have courtesy of SinisterSS. Rick has been a big help but I don't want to wear out my welcome with questions.

[joecar]

INJDC shows that the injectors are turned off, and the wideband AFR shows this (there's something like a 100ms time lag in the exhaust path).

Are you hitting the rev limiter...?

[Chalky]

I could have hit the limiter trying to log in SD at higher RPM's. I was looking at TPS and not looking @ RPM. Limiter was set @ either 6600 or 6800 RPM!

I have been kind of concerned with high INJDC and when the spike was pointed out, I thought the two could be related.

Thanks.

Get back out there and keep logging so you can answer all my questions.

Andrew,

Here's my latest tune file and the latest log file I used to apply VE corrections (i.e. don't apply this log file to the tune, I already did it).

Car is 2001 Trans Am WS6, stock :notacrook: (other than LT's w/cats, TR6's, low ohm sprial wound wires, 180 degree thermostat, and OLSDPE w/DFCO).

Cheers,
Joe

Andrew,

I just realized I neglected to filter out DFCO when making OLSDPE_0122.tun,
so here is my previous tune OLSDOE_0121.tun that I logged OLSDPE_0123.efi from.

Sorry to mess you up with my stupidity... :bash:

Cheers
Joe

Mind sharing the finished product?

Mind sharing the finished product?If it's okay with Andrew it's okay with me.
