2G: please look at my log

DSM's 4 life · 07-05-2012, 12:29 PM

I have posted this strictly in the ecm tuning section but no one seems to see that form as I am getting no responce so I am posting a new log here please take a look.

Ok, you def need a WB. Then follow videos on ecmtuning.com to get the basics down. Get combinedft near 0 during closed loop operation.
Next, your coolant temp needs to hit 180 or you can use coolant offset in link(iirc, no personal experience). So warm it up nice, then grab an idle log.
Your airflow/rev is too high i think. With crower 272s i have mine near .32 or so. Not a critical thing, but something you might want to get dialed in a bit better with your maf sliders(assuming of course you ARE using a maf, i dont know from profile and i noticed mafsd in there, not sure about that)

Basically get the wb, go from there. Its not too hard. Yes it is very difficult to get knowledgeable people to weigh in on your log. Jus tgive it time and post up a better log with wb and maybe a pro like MY1G or craig will show up. I have limited tuning knowledge but i do know the basics of how things work. Hope i could be of some help to you.
Hell, Ive got my own problems, im just a bit further along than you. Look 2 threads down at mine lol.

edit, i see as you heat up, airflow comes down. So dont worry about that.

Thanks I'm new to this whole tuning thing but hey I have to start somewhere and I am haveing trouble getting started since this topic is left to the professionals. I actually just purchased an aem eugo wideband used locally he had it hooked up on his rear o2 should I do that or use the front o2? A local tuning shop near me installed it for him "innovative tuning".

boost97gst · 07-05-2012, 06:52 PM

I run my lc1 in front o2 location and sim narrow band. Works very well. The AEM wb is notoriously tough to calibrate and get to work well with link. But alot of guys do it. Theres plenty of threads on AEM wb solutions. So grab that, get some op temp idle logs and i can help you out for sure. I have some downtime anyway, waiting on low temp tstat, some ducting, and some nice COOL nights around here to get some solid 3rd gear pulls at 27psi.!!! Im so close to big HP numbers yet so far away lol, always the case and with dsms, your always chasing 1 problem or another.
Post a log up after wb install and ill help as much as i can bud.

finally got my new 02 housing in the old front 02's threads were stripped here is a new log Im not sure if I did this collecting the correct data let me know.

c2ypt1c · 07-18-2012, 09:30 AM

Are you running e85? You need to enable narrow band o2 simulation and adjust your TPS. Then post an idle log...
Also, your profile says you are using 550cc injectors, yet you have global fuel set for 886cc, base fuel pressure is 37.5, and your stoich is 9.8:1 (e85?)
I would revert the TimingMaxOct table back to stock and zero your sliders as well...

boost97gst · 07-18-2012, 10:56 AM

you still need to grab a log with it atleast 180 so the fuel trims are leveled out and i can see whats up with your maf. There are other issues ill address later when i get home from work. And yes: what type fuel?

DSM's 4 life · 07-18-2012, 08:04 PM

Premium pump gas 92octane
What should my injector dead time be set at?

You need to calculate it. Click the "calculate" button on the fuel tab in ecu config. Use 550cc injectors, 42.6 fuel pressure (or whatever your AFPR is set at, but stock is 42.6), and 14.7:1 stoich...you really should watch the ecmlink demo videos and read through their wiki.

EDIT: Just realized you asked for dead time, this is to calculate global fuel. Just set deadtime to 0 for now. ALSO, unless your log has changed, I must have been looking at another log when I thought it was yours...Looks like you have it set correctly

I have watched all the videos i did have my injectors calculated in the previous log but I still am running rich

edit:
I enabled wideband simulation and set my deadtime to zero I will post a log in the morning before work thanks for the help I really appreciate it.

Yeah I was looking at another log at the time and thought it was yours, sry bout that

I'll be waiting for the new log

Bump fuel pressure up to 43psi first. Then recalculate globals. Should be closer to -15 or so. If you have 550ccs they dont actually flow 550 cc. You have to find out what they REALLY flow to accurately calc globals.
After your global is dropped see if you start getting near 14.7. Your lean as hell, especially for a cold engine. Your showing 17.7 and it doesnt move hardly(which is a bit conspicuous... would double check wiring to be 100% sure). Thats way to lean for idle.
Then, after car is at op temp!!! 180* pleeeeeez lol. Get your combinedft's in line using deadtime and mafsliders if afrest is off too much. Make sure your tps is set up properly,its not too hard to get fixed.

IIRC, if your afrest is too lean(which it is) then use the slider in that hz and move it down, i think to get it closer to 14.7 at idle. Then use deadtimes(most likely increase) to richen your mix up to match the afrest.
Do globals first and foremost, i think theyre off. I estimated actual flow at 530cc at 43psi and got -15 global. Your a 2g so 43psi is what is needed.
Also have you thought about simming narrow band? Would be so much easier to work with IMO. Whew, thats all i have for now. Play with your 50hz slider and move it down some and check airflow/rev and afrest. Then watch the videos on ecmtuning and youll be good to go dude!

DSM's 4 life · 07-19-2012, 05:32 AM

I don't know how i could be lean my car reeks of fuel when it runs my wide-band is just showing lines when I give it a rev it goes to 14-15 and then goes back to the right to 17 and reads lines.

the small adjustments I have made thus far have helped dramatically with the idle but the fuel injector calculation keeps giving me -18 I inputed -15 like you said my base pressure was always 43 so I'm not sure what you want me to bump up. here is another log now I'm off to work should be home around 9

I'm not sure if this log got to the *180 you were looking for but my garage reeks of fuel cant really keep it idling like this for long or else I will probley affixiate myself. and yes the door is open

c2ypt1c · 07-19-2012, 08:13 AM

Your frontO2 (simulated narrowband) is not occilating correctly in closed loop and it's now causing you to run super rich at idle (11.4:1!). Your coolant temp is < 180 so you'll be a little rich from that. However, I suspect you need to calibrate your wideband because it significantly differs from afratioest. here's a good video on how to do so:

http://http://www.youtube.com/watch?v=k3BIR6OOphg

But you might want to take care of your "volume airflow circuit malfunction" first...

boost97gst · 07-19-2012, 10:20 AM

I agree, your not cycling properly. However the only value i see is "aemuego inlinewb" Thats pretty consistently reading 17.7 which is lean as hell. Calibrate that first. It has to be messed up.

DSM's 4 life · 07-19-2012, 06:09 PM

I watched the video but I am not sure how to do the last part since I am not running speed density.

I attempted to use the adjustmet idle knob have it set at 8 currently here is a log my wideband is reading values but Im still running pig ritch

EDIT:

I was messing with my maft and found that if i set it to 3.5" gm maf It greatly reduces my throttle lag when I get on the gas.

I then attempted to adjust my "Base idle knob" but from what you guys are telling me I am running lean but that makes no sence... when I turn my knob to the right to lean the mixture my gauge goes to 14. ratios but doesn't that mean that I am running richer

I will record a secound log now with my 3.5'' maf selected and 8 selected on the base knob
