bumping this thread so that I can come back to it.

just thought id post an update
basically my injectors wanted a fuel flow rate of about 69 across the board. No idea why. Also ran essentially stock ls1 injector values for everything else and they...
correct. Im trying to completely stay out of closed loop so that I can accurately tune it as close as possible open loop. Then I will re-enable it for smooth cruising and such. I know some people run...
no-one? nada? :(

Posting a 2nd thread
My current iteration of my tune has still lingering problems.
I can only get the idle to lean up to about 13 ish with VE no matter how low I go, but it shouldnt need that...
So I made some headway. I lowered the mimimum pulsewidth and default pulsewidth to .593 and it seems to be alot better. It still idles way lean right after starting then works down but only drops to...
I would disable the air pump then.
Yes, open loop eq ratio. 14.7/.83 = 17.7 AFR. To maybe ease tuning I would set the whole table to 1, or copy in the stock OLFA tables then tune from there....
mods? stock injectors? is your wideband scaled and calibrated correctly?
Forgive me if anything sounds stupid because I'm a total rookie tuner, but just some things I noticed:
Do you have an air pump? Its not disabled. If it needs disabled the temp should be at 285 for...
a loud whistle at idle is probably a vacuum leak. seeing as your map sensor wasn't showing anything, Im guessing you might wanna start by looking around in that area... lol
Gotta post some details on your setup, and a tune file would be nice too. Post your config with a log file as well.
Just based on what I could see in my config, is your MAP sensor reading at all?...
KPA is down near 35 at idle. That seems pretty damn low. attaching a log and config file.

So all of my injectors on the passenger side have vacuum leaks. All the drivers side ones are fine. I bought some fuel rails off eBay from a guy "Fasster". They look nice and seemed nice but Im...
I copied your short pulse adder and minimum injector pulse data, ran super lean. added the ifr and offset tables, wont start at all lol.
got it. the question is, how do I get a baseline for my offset values? I copied the 0kpa column across the table. Immediately upon startup it went kinda lean, 16-17 afr. It then leaned out and was...
it is set to .002 right now, which is what I read from dsteck and a few other people. Or should it be .02?
Im not really sure I fully understood that document, nor do I have the stuff required...
On that note... is there anything else in the tune that seems goofy or off?
I have it failed in 3 other places.. but I'll change that too, thanks!
Holy derp, I guess it never occurred to me that the voltages shouldn't change either. I just figured "copy banish's data...
I am pulling my hair out on this one. I cannot get the car to idle around stoich.
