k guys, i'm a TOTAL noob at the tuning stuff. got the EBL up and running, and for the most part i'm getting the hang of it.

the thing is, i can't get it to idle at all. when it was cold this morning, it actually would sit there and idle, but once it was warm, no way. it sputters and loads up real bad, and smokes (black). i do have a couple datalogs, but i cant for the life of me figure out how to get them and post them on here.

but to me, it looks like i'm lean or something because my BLMs are high, where for the rest of my tune i'm on the rich side. my VE graphs look way odd from what the "stock" EBL one was too. every time i drive it it seems to want me to -10% from the same areas.

so if you guys hook me up with how to get my EBL logs on here, then maybe you could help me some more. this tuning stuff is addicting though. my g/f is already getting pissed at me and i've only been at it for a day...

thanks a TON in advance. any help is awesome to me, cuz i hella suck at this stuff.

One thing at a time.
If warm idle is rich, then start with that and lean it down until it runs. Once you get that done, and that it started OK before, if it's hard to start cold after leaning the VE tables down, you know your going to have to add fuel to the cold run. Be sure to say the .bin files as you go, labeling them so that you can easily backtrack.....

Might recheck your BPC calculation.

 

fast355 and Rbob both checked the BPC and said it was ok.

 

If the O2 cools off it will show lean which can force the BLMs up which further cools the O2 and makes the engine rich. If you have a heated sensor (which you should have with LTs), then lean out the idle area. Keep an eye on the BLM's. If they are going up and the exhaust goes to black smoke, then something is up.

If the O2 is cooling hold the RPM's up to clean off the plugs and heat up the sensor. Then let it idle and see what happens.

Can use the Learn VE screen (even if not in learn) to see the RPM and MAP cell you are currently in. Then start pulling (lower) fuel from the VE table in that area.

LIke grumpy says get the warm engine stuff correct first, then move on to the cold stuff.

ok, so yesterday when i was working on it, i was watching the VE learn screen and noticed that when rpms would drop down, the MAP would go way up, and then would come the black smoke. so do you think i should lean out those high MAP areas and see how it goes?

the VE learn doesn't ever tell me to take fuel out in those areas, is that because it gets out of closed loop when it does that?

 

>>so do you think i should lean out those high MAP areas and see how it goes?

Yes.

>>the VE learn doesn't ever tell me to take fuel out in those areas, is that because it gets out of closed loop when it does that?

The main WUD screen indicators will show whether the ECM is in BLM learn mode ior not. Did the Learn VE color block turn from yellow to green?

RBob.

 

i'm not sure. i will try it again later hopefully. how much should i lean it at low rpm, high map? 10% or more? sees like every time i drive it w/ VE learn i'm told to lean it 10% in many of the same areas.

 

Leaning by 10% can't hurt. If you go too far the engine will surge a little, then just add a half that back in.

As for the VE Learn leaning it by 10% is the same areas, make sure that you keep selecting the new BIN each time you re-learn. Otherwise nothing will change.

As it is let the VE Learn do it's job. It does work and is using the BLM values. There is a limit on both the BLM low and the amount of correction. So depending upon how far off it is, will affect how many interations it takes to learn in the VE.

that is kinda what i thought. when i started, my BLMs were 108, and now they seem to be getting better, so i think its working.

thanks bob
