I wouldn't want the computer and the interface to share a ground - that sounds like trouble. My inverter "floats", meaning no ground. I was careful when I set my system up, but few know how to do this properly and AE will just say "Don't do it."
I never even considered an issue when using my power converter in my trucks. I use a Lind Automobile Adapter Model #DE2045-1320 FA
Paid about $125.00 several years back to power my laptop before I bought the AE software. I bought my software (AE) a month ago and have used the diagnostics 4 times on 3 different trucks without an incident.
Here's the specs:
Designed for the Dell laptop D800, Ispiron. Input 11-16 Vdc 10 Amp Max
Output 20 Vdc 4.5 A Replace fuse with 15A 32v mini fuse. Assembled USA.

hmmm,
My early version of AE does not say I cannot power the PC from the vehicle, it just says to use an isolated ground inverter. Not knowing if my inverter was IG I tried it and all that happened is that AE would shut down immediately. Then I got the inverter that Tugly uses and all is well now.
Thanks to cjgray1974, I have a large sampling of data. I need to convert it from Infinity to AE for graphing, as soon as I get more than 15 minutes here and there. I can say his data showed EBP, BARO, and MAP all at 14.2 PSI with KOEO - perfect for a truck at 1000 feet elevation. That truck gets a seal of approval for having a good reference for everything that follows... unless cjgray1974 lives in Denver.

Does the truck have a name?
I live at 1000 feet. As far as a name I named it Black Beauty when I added it to my garage but not sure if its gonna stick. I just bought the truck in December.

AAGGHH!! I'm within a gnat's breath of getting the Infinity data formatted to be read by AE, and that timestamp is setting the whole project on fire. The timestamps on Infinity are a completely different format and the sampling rate is too fast for AE to digest, and there is no way to fix that other than put a fake time in there that is compatible with AE.
AE reads the volts on the BARO sensor and that's it, nothing else. Infinity converts the BARO volts to actual PSI.
While Infinity has 15 times the data reporting of AE, much of the reporting is the same data being repeated. In actuality, Infinity is roughly 4 times faster than AE, which is still pretty respectable... but I don't like all the repeat data that I had to sift through.
Looking at the data, I can see cjgray1974 has issues to resolve and this was a perfect data set (so much of it) to really show something interesting... but it's advanced stuff and we're not to that point yet. We need to understand the AE alphabet before we can read its stories.
Somebody please throw me a lifeline and give me some AE data (other than my own truck), using the instructions I gave about 1 or 2 pages back. I want to get over this hump quicker... as I'm sure some of you do too.
Are you trying to open the data from infinity with ae? Have you tried eec analyzer or something similar?
Opening with AE would never work... the files are about as different as they get for being text files. I'm organizing the data, using AE rules of "grammer" so that I can open the files with AE... but the time stamp is the challenge. I tried organizing the time from Infinity in AE format, but the sampling rate is too high for AE to recognize. I can see the data and graph it, but I want to show an AE screen with stock data... which I don't have. I had to get on with my life, so I set it aside for now.
I recorded data, using my "homework" criteria... but I have a 38R, 4" exhaust, big sticks, and a boost fooler. MAP and EBP will not compare with a stock truck. The BARO data is pretty cool, I drove over a mountain pass with AE recording. I'll post that part when I get a few minutes more than I have now.

Give me two hours and I'll get you some data. Have to put the Toughbook on charge and reflash the PCM to stock tunes.
