So I installed EFILIVE at my shop also to put it up on split screens and noticed that my laptop is a older version Efilive- when I modify the file at my office it wont open on my laptop- I wonder if this is why some cant read some of the files I upload


if I update will it mess all my files up on the laptop?

Updated efilive can read old tunes. Update the laptop and you'll be fine.

I have a feeling the reason I can't see your maps is cause of something I'm doing wrong.

Some things:
- in tunetool, go Edit->Properties and set VE units to g*K/kPa and fueling units to EQR, click Ok.
- in each of your maps, goto the Data tab, set Precision to 3 or 4.

Hint: SELBEN should be within the range 0.80 to 1.09... if it is outside that range, then something is going wrong.

What are you saying is not alright...?

this is my ve table before I paste with multiply - something just doesn't seem right at all

[joecar]

Sanity check:
1. you are doing Calc.MAFT to correct the VE table (ignoring the MAF calculation portion for now)...?
2. you are getting a MAF DTC (which causes PCM to use only VE)...?

Updated efilive can read old tunes. Update the laptop and you'll be fine.

+1 what JetMech said...

when you update V7 software, read a .tun file and immediately save it as a .ctz file... this is now your tune file.

Just seems like the 10.xx number drop seems a little extreme. But I'm not a pro. The graph has many spikes which I know will need to get smoothed. . Plus when I tried it the truck for sure wouldn't idle

I'm on vacation I'll have to check all the settings when I get back.


Thanks for the help you two

...

Your pasted-multiplied VE table looks quite good/clean.

run it and take a log, let's see the new BEN values (when you get back...)...
