EFI Live V7.5

[Fast1995z1999ta]

Im looking at my 1/8 mile pass data log and I cant scroll back the frames or cut the data log to get just the pass and eliminate staging lanes and return road. Also my logged AFR is way off showing 5.something instead of 12.6? I am very new to this stuff ( tuning and using a computer not new to drag racing! lol) , thanks

Post your log file.

Not sure if this works? 5,500 I start the burnout and I think my launch is at 5,700

this was my first pass and slowest one for the day somhow between shutting the car off and back on in the staging lanes I didnt get the others but I know for tomorrow when I go back to check just before the runs

Per Data Log:

RPM Timing AFR
5,400 25 4.45
5,700 25 4.32
6,100 25 4.33
6,500 25 4.04
6,900 24.5 4.10
7,200 24.5 4.20

In car camera shows AFR gauge reading this:

4.400-12.6
4,500-12.4
5,000-12.6
5,500-12.9
5,700-12.7

I see it too. Have you tried programming the FlashScan's to read your particular Wideband?
You can do it in V8. Or the front panel. I'm thinking you have a setting wrong somewhere between the incoming serial stream and output to the datalog.

Just an observation, your timing is awfully flat for a pass. It seems to be 25 degrees throughout the whole pass. From 2800 - 7000rpms

yes it needs a tune bad, I figured out how to adjust the AFR buy not the timing

Something is not right.

Do Info->Validate Pids

and capture another log.

[Fast1995z1999ta]

For some reason those options are not Highlighted on my program. I cam see them but can't click on them. It seems like I don't have the full version or something?

[Fast1995z1999ta]

maybe it's because im looking at it on my desktop and its not hooked to the car?

did that see attached24260

[Fast1995z1999ta]

this is my tune24261

[joecar]

I'll take a closer look over the next few days.

Yes, plug in to your PCM and do Info->Vaildate Pids.

thank you, it is still logging the AFR wrong I dont know if there is another way to calibrate

In this log it looks like the wideband was not connected or powered up.

In this log, wideband pid EXT.WO2LAM1shows running rich at ilde (as low (rich) as 0.4 lambda.

Are you running E85...? Did you program your FSV2 for stoich of E85, is this the AFR data returning from the WB...?

I see EXT.WO2LAM1 respond to throttle, but it is indicating excessively rich.

You narrowbands indicate you're almost sufficiently rich at high load (~900 mV vs 920 mV) (but the NB are not a good indicator).

Main VE is missing data in some areas.

MAF doesn't look right.

What is the int/exh duration, lobe sepration and advance of your cam...?

[joecar]

You have to log GM.EQIVRATIO so we can compare with EXT.WO2LAM1 to see if your MAF and VE are correct.
