first datalog of new turbo combo
got a log of an idle situation....I'm trying to get this dialed in. I realized I messed up and didn't datalog some parameters I should have...I'm going to try and get another tomorrow with all the right things in the payload but until then...if anyone can take a look at this and give me some ideas I would appreciate it......It 'looks' like idle AFR is hitting 18 and sometimes 19!!! YIKES!!!!
|
apparently I can't post a datalog... since they're CSV. files hmmm

I will be up that way this coming week going to Bob Kurgans shop if I have time I will see if I can swing by... |

I think something was up with the computer (A9P) so I swapped in a C3W I had laying around. I will try to see if I can get a log tomorrow.... I'll see if I can attach it as something else. Brad |
still trying to get this going, I haven't had much time to work on this and things are still hokey with the AFR in the 15-17's!!!!! Commanded is around 13 and some change, I think...SOOOOOO I'm thinking I need to get it some more fuel???

Make sure you don't have a vac leak. Getting the LAMBSES to match what the WB is seeing is definitely first.
|
ya, that's what I've been reading about...just trying to figure out what to adjust to get my AFR (15-17) to match the LAMBSE of 12-13
|
One other thing, make sure you don't have an exhaust leak as it will give false readings too. Is the AFR you are seeing on the gauge or in EA? If it's in EA make sure you have the offset set correctly for the type WB you are using.
If all that checks you can either adjust the fuel table or the MAF curve to get it to matche commanded AFR. Oh and be sure you force open loop while doing all of this and clear KAMREF. |
I've got a LC-1 wired into the computer (eec) through the pin for the egr, and I've also got it where I can just use a serial cable. I'm viewing all this in BE and EA.
There is a SMALL and I mean small exhaust leak on the PS (one of header bolts is stripped out and I couldn't get it to seal ALL the way. Hopefully that wont make a HUGE difference in the AFR. The other thing I was thinking about was when I set up the LC-1 it has where you can set it for GAS (14.7) or E-10 (14.08)....and I set it for 14.08 cause on almost ALL the pumps around here they state that it "may contain up to 10%ethanol)....Am I wrong by putting that in that field? (14.08) I'm going to try and load a tune with it set to 14.7 and see what difference that makes. |
There are several good threads on eectuning that talk about setting it to E-10 personally I don't see the need on pump gas because the blend changes a couple of times a year and you never really know.
IMO the exhaust leak even though small will be an issue simply because you have no way of knowing how much oxygen it's letting in the exhaust stream and how much of it is saturating the WB. As it goes through several heat cycles this amount will change. An exhaust leak never gets better on it's own only worse over time. You said you have the WB tapped into the EGR pin, is it on the ECM itself or are you tapped at the other end? It really needs to be at the ECM so that the signal doesn't degrade from resistance due to wire length. |
at the ECM. I've been messing with this all morning, enbled FN1360(with the code patch and all) got AFR to come down some by changing startup open loop table rows. AFRs are showing 7's and then at 5 seconds into datalog it jumps to 16's. OH, and for some reason the tag on the dashboard for OL/CL is reading CL, despite "forcing OL" being enabled....:headbang:
|
Have you calculated the % change in size of your injectors and added that to your fuel settings?

I FINALLY got idle into a reasonable level...13-15, adaptive OFF, Forced OL, started changing shit till it sounded right..in Fuel Base OL.....FINALLY, now it's leaking oil from my oil drain going into the pan!!! my car--->:chairs:<---Me |
Its always something! lol Sometimes i wish my car was bone stock cause the stock ones never give any problems!
|
you're right!
|
Brad, not going to be able to make it by. Had to spend more time at my mothers than I had originally planned she has not been doing good health wise. I am planning on making another trip up in November to check on her again. Pm me your location so I can see how far you are off of I-20.
|
no problem Dale, family first man!!!!!

also latest datalog...
|
Probably be tomorrow before I can look at it but I definitely will.
|
that's cool, I've got a ton of crap going on right now too...trying to get ready for NMRA this coming w/e.
Thanks again. Brad |

no problem, man you have had your hands full....I'm not worried about it...if you get to it great, if you don't no biggy!!! I'm in Milner GA. 30257
Thanks. Brad |
Brad, I haven't forgot about this just been really busy with work and getting ready to play at the fair this Thursday. I will get to it.
I kinda got a little bit ahead of myself. The injector changes were for cranking PW. Calculate the difference between stock injectors and your current ones as well as the CID difference and multiply all the values by that number. It will greatly help startup. |
cool, thanks man, I haven't had time to mess with it, we're at NMRA Bowling Green, and leaving tomorrow to head home. Once I get home I'm going to be WFO with my landscaping business...I had I don't know how many calls I've had this w/e while we were at the races...
|
I tried to look at the file and datalog but it gave me a bunch of errors. I think something might be up with the program on my laptop. If you can email them to me in the original format and I will try again.

aight, lemme try again then....I haven't even touched it in over 2 weeks since I've been messing with my son's car....
|
SENT, also sent most recent bin, and the first "initial startup" bin and the latest log
|
Brad it looks like I'm going to have to back up and punt. I can't get the tune to load in my copy of BE, it gives me a ton of errors. I'm sure it's the program so I guess I need to uninstall and reinstall and try again. As far as the datalog goes, Clint has that disabled on the free version so no dice there.
|
haha, no problem, I've not messed with this thing in over 3 weeks. It may be operator error on my behalf (most likely)
|
guess I need to find someone closer to me to help me through this...I'm such a "visual" person. If I can see something being done and what happens as a result of that, it generally sinks in.
