Running lean after tune

[SRT10KLLR]

I was dyno tuned a couple months ago but recently switched to AFR 225 heads to increase cr from 8:1 to 9:1 and adjusted the tune likewise. I had a buddy of mine check/retune and he said my VE and MAF were right on. The problem is that my LTFT's are at +25% and I keep getting a lean code for Banks 1 and 2. He told me to check to make sure my MAF was plugged in correctly(which should be since we did not unplug it) and to clean it. Also, to check my 02 sensors to see if they are plugged in correctly. I am going to but some MAF cleaner and spray the MAF just to make sure it is clean and plugged in correctly.

What could be causing my lean condition?

Also, I noticed that when logging if my tune file is also open I can see where I am at during driving as far as the Main VE table and/or Spark tables go but the Main VE table is not referencing the same Kpa as the log.

:help: Anyone :wallbash:

I don't want to drive it if I am truly running lean especially with an annoying "Check Engine Light".

Do you have a wideband installed in the car? Were the injectors/regulator modified? The heads were all that was modified and the fuel trims went from 0 to +25?

Hi SRT10KLLR,

You need to set up the units for MAP to be the same in both the scantool and tunetool (set them both to kPa);

have a look st at these thread:

Basically in the tunetool go Edit->Configure Display Units and find B0101 and set the row/col units to Metric.

If your LTFT's are that much positive then you may have some airleaks.

Can you post your log and tune files...

[SRT10KLLR]

Here is my tune and log.

BTW, my Main VE table has Kpa and so does my log but they may not be reading the same thing.

Do you have a wideband installed in the car? Were the injectors/regulator modified? The heads were all that was modified and the fuel trims went from 0 to +25?I swapped out to 60lb injectors a while back ago and had it tuned with them. Since then I only switched heads and removed the cats. Right after the head swap I retuned on a Mustang dyno and have run with positive 15-18 LTFT's. I made a tune based on the first dyno tune with the old heads and the new tune with the new heads and used that as a base for this last tune.

A buddy of mine made a couple changes but said the VE table was pretty much "dead on" and the MAF needed very little adjusting. An Innovate LM-1 was used for the tuning and it was done on the street. :help2:

Thanks

BTW, I know that log was pretty long. I was driving home(about a 45 min drive) and made about 9 logs on the way. :grin:

SRT10KLLR,

So now your log->tune MAP kPa linking is working correctly...? :cheers:

Long logs are fine, I have some hour long logs... :)

Be aware that you have 35 channels selected in your log (update rate is 5 samples/second)...
If you get the channel count to 24 or less, you will update at 10 samples/second.
(see channel count at bottom of PIDs tab display).

Cheers
Joe

Yes, the MAP kPa linking is working now, thanks again.

When the tuning was being made the channel count was a lot lower.

Did you see anything wrong/out of the ordinary in my log. I have more logs but they are also from the same drive home.

I looked at the log and tune files briefly and they looked fine to me...
I can look at them in more detail later today (when I boot up Windows :)).

Joe, since you were able to fix my logging MAP linking I will throw one more at you. The dyno operator/tuner used my laptop to retune after he installed the heads and now whenever I try to monitor my Dashboard(B) it automatically goes to "recording" and pauses it instead of "monitoring". It used to allow me to monitor without recording.

[SRT10KLLR]

Bump. I logged a couple more runs today while making some changes to my TCC. Tomorrow I will clean the MAF with the electrical cleaner I bought and check the o2 sensors. I will also swap out the MAF and o2's from my brother-in laws 5.3 Suburban just to make sure. I don't think there is anything wrong with them but will check them any ways.

[joecar]

BTW: I got busy, but I'll still look at your files in detail.

Monitoring is just a way of starting recording in pause mode. That's how its always been. When you are monitoring, if you want to start recording just press Ctrl+Spacebar or click the pause toggle pause mode on/off.

While monitoring, if you never un-pause then when you stop monitoring you should not be asked to save any data because no data would have been recorded.

PaulPaul, I understand that and it used to work that way when I first ran the scan tool but now it does not run that way. My dashboard B does not have the "yellow" or "red" buttons active. They are only in my dashboard A and when I press the "yellow" monitor button in dashboard A it goes to a "paused record" action on my dashboard B screen. The dashboard B no longer has the monitor function. This happened after my tuner used my laptop to re-tune after he swapped out my heads.

How do I get it to work like it used to when I first installed it? Should I re-install the software or is there a way to go back to factory seting a better/easier way?

BTW, it has been cold and rainy here so I have not had a chance to clean the MAF but I doubt that is the problem. Also, I noticed a 8% change in the MAF between my previous tune the the current tune even though it was supposed to be right on.

There are four things you could try in this order:
Select the menu option: Dashboard->Recall Installation Defaults->Reset "Default LS1" dashboards.

If that does not help, delete the EFILive registry settings which will reset ALL software settings to installation defaults.
1. Make sure no EFILive software is running...
2. Click Start->Run, enter regedit, click OK.
3. Navigate to the key: HKEY_CURRENT_USER\Software\EFILive\V7.5
4. Delete the key V7.5 (and V7 if it exists)
5. Close the registry editor.
6. Restart the software.

If that does not work, re-install the software - select the "delete registry option" if you are asked.

If that still does not work:
- Uninstall the software
- Delete the registry (as per above)
- Backup all the *.efi, *.tun, *.pid files that you want to keep.
- Delete the folders:
\My Documents\EFILive\V7.5
\My Documents\EFILive\V7 (if it exists)
\Program Files\EFILive\V7.5
\Program Files\EFILive\V7 (if it exists)
- Re-install the software
- Restore the *.efi, *.tun and *.pid files that you backed up earlier.

Paul

Hey Jimmy,

I'll be back in your area pretty soon and can take a look at it for you again. Shoot me an email and I'll set you up on my contact list when I come back through.

Bringing this back up.

I installed a wideband and did some logging. The wideband shows my a/f is normal but yet the fuel trims still show as being lean. The O2's seem to be functioning correctly. What could be causing this?

I attached a log with some normal driving along with a couple WOT bursts.
