Second that motion.
I thought I had my own copy of those screen shots - looked on three different laptops and no luck.
Maybe Keith could host them.
Thanks in advance.

Mine is on 4

Cylinder charge temperature bias set @ 1.00 gave me better a/f consistency after reconnecting the maf...

I listed the user defined sensor as o2 - should have been Air Fuel Ratio.

Works now

:yay:

After changing my LC – 1 from the default selection in the table for widebands to a user defined offset formula my Air Fuel Ratio Error is no longer supported.

The function string is...

volts/.625 + 10

HPT & LC-1 - matched the afr #'s

Plugging the LC-1 O2 default back in and the HPT readout jumped 1.2 AFR points over the LC-1 readout.

This over corrected by 2x in the other direction.

volts/0.625 + 9.75

seems to be very close.

In the scanner open the table display. Right click on the EIO 1 (if that's where you wired w/b the output to). Left click "insert". Expand "user defined". Double click "configure user defined"....

User Defined Enhanced IO Inputs ??

After following the directions I get a steady 16.06 AFR.

volts/0.625 + 8.64

Where do I plug the formula in??

if you see anything other than 14.7 then you need to adjust your formula slightly
as an example
if you saw an average of 14.5 then you woule need to shift your minimum AFR by 0.2
so the new...

Fixed it!!

:yay:

I just gave it a try and it fixed the cut off problem. Thanks for the PM on this issue!!

Hey Mike,

You're right.
PROPS to all the guys that jump in with the info!!!

If the MAF table value is raised by 25% will that cause the A/F to be leaner or richer?

Start with your current file, then open a stock file in compare - same year as yours. Go to your file - the different settings will be in green. Copy and paste from the stock file to your file until...

Go to the bin repository and download a stock tune. Compare the stock tune to your tune. Call the tuner and ask about every single change he made and why the change was made.
Your spark advance...

I had this problem and was given the advice here to turn off the air pump(raise on temp to 284*) which eliminated the lean AFR at cold start up.

DFCO ENTRY RPM:

1st 7000
2nd 1840
3rd 1840
4th 1840
5th 1800

Same here - I start in 3rd around 1000 - 1200 R's hold wide open until the revlimiter @ 6200 around 95 mph. Then push in the clutch to avoid any back pressure/lean a/f readings.

I set the PE table @ 1.150 which equals a commanded 12.7 (14.62/1.150).
Then adjust the VE cells that correspond to the commanded cells that you hit.
You need a wideband to do that.

When my car goes into reduced power mode - it's like only 4 cylinders are working. Is yours doing this or is it just a DIC notice?

I sent the interface box in for the EIO recall. I never received any info on a cable recall.

I've been dealing with this for a while now. Scanner stops scanning after 10-15 minutes. It used to be after 20-30 minutes. I'm using a Dell Latitude 810 with a serial port and the serial cable...

That VE table is pretty constant at 14.6:1 in different weather conditions.

I had a good MAF...
