ECMlink First pull almost to redline

[GSLENK]

I got some knock so I decided to back off.

Eh, I clearly have to start over. This is a terrible log. Further down is my Idle log. I guess that's the start over point

Look at the LTFT himidlo .elg file a few posts down. this 3rd gear pull posted in this post is practically irrelevant except for all the comments made on it.

It is running quite a bit lean thats the first issue I would fix. after that do another pull if you are still getting knock raise the timing up a bit might be trying to fire too soon.

WTF a little lean

20 psi and 13-14:1 AFR's? I Say that's a bit more then a little.

Slow down, your not even logging your fuel trims...

You have adjustment made in MAf comp? But are running SD and you VE map looks untouched for anything under any load.

have you Actually got any amount of dialing in for cruise an lower boost ? I think not if your not even logging the trims...

Quit doing pulls till you can post a log that's not cut down to just a pull and have your Ft's in it... .

 

[GSLENK]

ok, fuel trims:

Thanks

 

[MY1GDSM]

Ummmm... . Nope sorry they're not.

 

[GSLENK]

Looks "dialed in" to me. But clearly something is wrong because I'm lean at anytime other than idle. I saw a ton of ecmlink videos. I have ~.25 gm/rev airflow, I have combined FT floating around 1-2% thats what the tutorials say to do. As far as im concerned I did what was right but I clearly must have missed something.

Link Wikis show how to adjust the VE table at idle, so the airflow is at .25 gm/rev then adjust dead-time accordingly to bring fuel trims down. I used track-datalog to find the box(es) to adjust for idle (for me its one box). Im using PTE 680s.

And how do you Dial in cruising? I thought there was a tool for that. Thats what I used. Is there a tutorial somewhere? You dont have to tell me how exactly, although It may benefit more than just me... But a useful pointer would help a lot.

Ummmm... . Nope sorry they're not.

They arent fuel trims? they arent dialed in? they arent what?...

Not being logged as seen from the last log here...

I just did this today. Check out the link and rewatch the #8 demo video, "Fuel trim". I literally watched it at least ten times before I dialed in the MAF for cruising.

Thanks for pointing that out. I was unaware that there are other important FTs than combined (noob mistake) thanks for being "patient" (mildly harsh) as opposed to a complete griller.

Heres a log with the missing requested values.

I watched it like 4 times, actually took notes . then watched it with my notes in car as I was setting idle. Only thing that was different, was that instead of adjusting sliders, I was raising/lowering the VE table numbers based on track-data log option.

I was able to find .25gm/rev and combined FT around 1% using the methods the video displayed.

TURN DOWN THE BOOST!!! Start over, thats alot of knock. Get your fuel trims right, then get your a/f on point at wide open with about 12psi of boost. When you get all that right at 12psi add 3-5psi until you hit your target boost while keeping a/f in check. Then play with timing. for your base timing map try a 2g map. Whats your fuel system consist of?

I forgot about turning down the boost. Will definitely do that! thanks.

Also my fuel system will be dramatically changing again, and more permanantly.
Currently:
PTE 680's
Factory fuel pump rewire (4ga to junction block in rear, 8ga to FP from junction block)

I have the following all in the mail on its way to mi casa:
-wally 255 + install kit
-FIC 1050's
-Fuel lab AFPR
-fuel lab 818 fuel filter
- -6an lines from filter to rail, rail to afpr
-fuel lab fuel rail with -6an adapters

^^^ should suffice.

I would like to know what Im doing with the current setup, so I know what im doing with the above setup going in in a week.

Where can I find proper AFR at different rpm/boost/load? I dont expect you to tell me all, unless you wanna but Id like to have a solid source.


I read the V3 config on ECM wiki, and it said that the 2g timing map is for 1gs with 2g low compression pistons. Am I wrong here? I thought I read It was ok elsewhere, but when I read ECMtunings description, I decided against it.

Are the 1g default ecmtuning maps for timing/fuel (AWD, '93) safe to use/tweak?

THESE: http://www.ecmtuning.com/wiki/v3configs
they are considerably different than "stock"

...if you are still getting knock raise the timing up a bit might be trying to fire too soon.

Huh?

 

[GSLENK]

Huh?

dont worry I most certainly took a lot of grains of salt with that. I assumed hes an engine rebuilder in need of more work... I definitely will not be doing that.

Are the 1g default ecmtuning maps for timing/fuel (AWD, '93) safe to use/tweak?

The 1g maps are very aggressive on timing, but overly rich on AFRs. I always recommend that people load up the 2g or Evo8 maps, as they are more conservative and make for a good starting point. Once everything is at least close, you can lean them out a bit and start dialing the in the airflow calibration and then start tuning.

 

[GSLENK]

Thanks for that info. do you have any preference (2g or evo)for my mods? they will be changing, a bit at the end of the week it will be: wally255, 20g, FIC1050, AFPR, and so on.

 

[Calan]

Thanks for that info. do you have any preference (2g or evo)for my mods?

I would probably start with the Evo8-mod1 maps, leave the timing as is, and change all of the AFRs that are less than 10.5, to 10.5. You just want something that is safe, but not overly rich.

Once you get the airflow dialed in, you can start raising the timing and leaning out the AFRs (in small increments) as you increase boost a couple psi at a time. But you want to get everything dialed in first.

 

[GSLENK]

Great advice! Now I am onto setting up my idle... Ill post a log soon. Im still waiting on a 255, but idle, and low boost should be ok to start logging right?

And adding a 255 shouldn't change that right? especially since im running an afpr.

It seems safe but weird to start at low boost. because what do you do when you raise boost? Pull more timing? What typically happens as you raise boost? is a better question i guess...
