How do I open my powerlogger files?

["Turbo-T"]

I did some runs tonight with the powerlogger which are saved in .dat file format, and they will not open when I try to open them.

I keep getting an error message of:

Quote:
Acrobat can't open "file.2.dat" because it's either not a supported file type or because the file was damaged.

My laptop is a Hewart Packard with Windows 7 on it.

Thanks to anyone who can help.

Did you try to open them with power logger? You need to load them and review on PL.

I tried to open them from the folder I saved them to but it's not working.

Forgive me as I have not used PL in a bit and I don't have my laptop with me.

Just like when you are watching data real time in the car, once the file is loaded you use the arrow keys to scroll frame by frame through the run. Once you have chosen the file, it's there.

From what I am reading, you say that when you choose the file, you get an Acrobat error from within PL?

I'm sure someone will chime in soon.

Where are the files saved? Are you clicking on the dat file to open them? That won't work.

 

["Turbo-T"]

Ok, I was told I need to change from a .dat file to a winzip file, I posted them here. Hopefully they'll open for you to review.

where you able to open them? I will look at them right now for you.

ok, this is what i notice.

not sure what you where doing but don't go into WOT OD. You got some knock there which is from the heavy load in 4th with alot of boost. not sure what ocatane you where running. I hope not 91 and alky but from the timing i see it probably is.


You have MAXED your injectors. 105.5 % time to look at a injector upgrade or add more alky to bring down the duty cycle?

You running a PLX? looks like it. if so looks like you could richen it up some but im guess its due to the inadequate injectors.

You have a TT 5.6 chip? i would upgrade to the 6.0 sine you have a WB chip. That will help keep your a/f in your target area.

WOT TPS looks good but i would bump it up just a hair to 4.60 if you can. per TT your ok.. For WOT, no less than 4.00, 4.40 to 4.60 is a good safe place to be. Don't exceed 4.80.

ok the above was file 1

file 2

Still INJ DUTY is @ 105.9

Not sure whats with the WOT 4th gear pulls and into Lockup.

blip of knock not sure why. Maybe false.

thats all i see.

Thanks for looking in my files. Glad to see you could get them opened. I'm not having much luck. I don't know why. :redface:

For fuel I run 93 octane with the alky.

On WOT OD, I was letting her run all out on an open road, but point taken, no more WOT OD runs.

For injector maxing, that's been something I've been asking about, but have been told by some on here "you're running alky, you're fine with those 36 lb injectors". How does the wideband AFR look during the 105% injector readings?

Yes I am running a PLX wideband.

Yes I have a TT 5.6 alky chip.

How do I bump up the WOT TPS to 4.60?

Thanks for the assistance.

Apparently you are trying to open your dat files "outside" of powerlogger.

Aint going to happen. You must open them with powerlogger.

How is that done you ask? get powerlogger running, either hit the F3 key OR click the F3 tab that appears on the left side of the powerlogger screen. ONce you're on the F3 page notice on the left half of the screen there are two imprtant buttons. "S.save" and "L.load" see those?

click the Load button and it will open a screen and there are most of your powerlogger files, and there should also be some .dat files there. Pick the .dat file you want to look at, then click open.

You can now, for example click on the graph tab on the left side of powerlogger and you'll notice the graph screens with a "slider" that you can click and drag across the screen.

The Powerlogger manual explains all this stuff. There's a wealth of info to be gained there.

Getting back to this, can the alky adjustment be done with the remote controlled box? Or is this an adjustment that is required inside the PAC?

You can add alky by turning the gain knob up on the black remote alky box. What is it at now? I have yeat to look at the logs but you may want to check the FP at wot in high gear too.

 

["Turbo-T"]

I've got it about 6.5. I don't have my FP tied into the PL....yet.

 

[jasjamz]

OK, some of the vendors sell a gauge you can mount under the wiper. You should really know where your FP is when tuning. Adding alky to bring the DC down is a temporary fix. I suggest you turn the boost down until you get some 60#ers or get the fuel delivery checked out. TurboDave knows his stuff! I just feel that you must have the proper parts to make power and use them accordingly. Alky is to supress detonation. It can bring A/F down, lower intake charge and other stuff, but for what you're doing, play it safe.

Acrobat can't open "file.2.dat" because it's either not a supported file type or because the file was damaged.

To answer the original question, Acrobat Reader has no idea what a .dat is; given no context, it is unsure what to do with the data contained in that file.

You could probably open it in Notepad or some other simpler text editor, but again, it most likely won't make much sense.

One thing you might be able to do to prevent that in the future is find where the Powerlogger.exe (or whatever it is that actually opens Powerlogger), remember that, then right click on one of your log files and go to "Open with...", and browse to your folder that contains Powerlogger. Also make sure you click the checkbox for "Always use selected program to...". That way you can open any .dat and the computer will associate that file with Powerlogger, and open Powerlogger to open any of those .dat files.

Hope that helps!

I have a FP gauge inside the car in the A pillar. I don't have the ability to datalog my FP readings b/c I don't have the required parts to send the info to the PL. FWIW my fuel pressure, at 23 psi is usually around 68 psi.

The interesting thing is some people say the 36 lb injectors (like I have) are good into the 11's. I've yet to get into the 11's but the duty cycle already comes up at 105%. Why?

 

[TurboDave]

I never saw a post whether or not you read my post #9 and had any luck opening the files in the proper manner?

You can have the pressure, but not enough volume. Which could mean the pump is not moving enough fuel. When was the last time you changed the fuel filter? 36lbers are only good for like 430 flywheel hp. Since you run alky you can make a little more with them depending on how much alky you are using. What type of time have you ran. Boost, timing, and about what you think your car weights will help you in figuring out where you stand.
Play around with the TCI racing calculators and let us know what you come up with.

Fuel Pressure

If you're not using an AC Delco fuel filter you'll want to start. I can't stress this enough. If you have a fuel system that is unable to keep up,it will make a surprising difference.

Sorry Dave, yes I was able to open the files and view them, thanks.

Fuel filter was changed Oct 6 2010. It doesn't even have 500 miles on it yet. Ran a 12.61 at 109, 60 ft. was a poor 2.00 due to bog off the line (no tire spin) but pulled real good once things got up and moving. That's on 25 psi, 23/21 timing on the TT alky chip, car weighs 3705 with me sitting in the seat. TCI calculator says it's 374 hp but doesn't say if that's at the wheels or the flywheel. Also I've read those calculators really aren't all that accurate. Also I've dropped the boost down 2 lbs to 23 since then.

Thanks, I can't remember what brand filter I put on.
