Which wideband are you using w/EFI Live?

[5.7ute]

Follow page 8 & 9 in the lc1 tutorial in the tune tool. That will get it in line with the supplied pid.

Wideband problem solved. Removed WB and did another free air recal.
This did the trick. Now A/F are where they are supposed to be.

A few notes:

1. When LmWorks is in logging mode or gauge displayed and key on, it will show percent warmed up for sensor. The startup screen is where you want to be


2. When doing a free air recalibration, the gauges will show the device is recalibrating for free air. Same screen selection as above.

3. I'm am not sure, but I wonder if you must program the a/f vs volts using LmProgrammer BEFORE you do a free air recal. This is really the only thing I did different from when I installed. After calling Innovate Motorsports, a tech stated this was not necessary. I would do it anyway.

4. For those who don't know. When you set the v vs a/f in the programmer, its a linear relation, so y = mx + b.

m = (a/f2-a/f1)/(v2-v1) = 3.008
x = any voltage v.
b = y intercept, at 0v, Innovate gives that a/f is 7.35v, so b = 7.35v

I have no idea why EFI just doesn't use 0=7.35 and 5=22.39. Instead EFI Lives docs recommend 0.8833 = 10 a/f and 4.21667= 20 a/f. I'm guessing FlashScan doesn't report a full 5v due to bit storage. Note, the slope of the line in EFI Live is the same.

5. When calibrating your wideband, note the amount of free air is
roughly 20.9% by definition. In my case, my wb calibrated to 20.8%
Make sure that what your wideband indicates makes at least some common sense.

You can make your own calc pid using those.

I use 0V=11 and 5V=16 giving me the equation afr = v + 11 for which I made a calc pid in calc_pids.txt.

When logging via BBL, I would like to add in the LC1. I am seeing the correct
voltages, but the AFR = 25 all the time. How do I correct this?

[joecar]

Are you doing serial AFR logging with V2 BBL or are you logging analof AFR with V2 BBL...?

In the scantool are you selecting the LC-1 AFR/BEN calc pids...?

Post a screenshot.

ANALOG V2 BBL. I didn't know we could do serial...gotta check that out.

This is a screenshot of a BBL I did. Note, that when I'm directly connected to the laptop, the data is correct. It must be something I messed up in options.ini?
Also, forgot to mention, when I add the LC1 in the PID list, no problem getting data. Is the BBL that I'm interested in. Trying to set up total BBL for drag passes through the day and only turn on the laptop for tuning/log review.

Hi all i have an ls1 monaro and got efi live doing bit of tuning on it as i have got a cam and a single plan manifold on it and have been told that plx devices wide band is the best what model is every one using and think that is fine to do the job?

TFZ,


You're logging analog AFR, so when you view your log in the scantool, at the PIDs tab select the LC-1 AFR/BEN pids and do File->Save.

The pids WO2AFR1/2 are for digital serial AFR, not for analog AFR...

If you want to log digital serial AFR, see these threads:

V2 serial AFR input (LC-1):
showthread.php?t=8115
showthread.php?t=7532
showthread.php?t=8348

You must enable it in the V2 settings (F4->F1->F1) and enable WBO2 in and select "Innovate", and you have to connect up using a null-modem serial cable (see links above).

So all I need to do is create a STEREO<-->RJ12 connection and plug it up. Nice.
