Thread: Which is easier to use... DHP Powertuner or an HP Tuner...

Read, Read, Read, then scan, then read, read, change something, scan again, scan again.

The only thing that helps is more practice and being able to work through the bumps you hit. Im sure there are other people reading this thread so I'll explain some of the basic stuff you will be doing or can do if your first starting and overwhelmed or unsure of what you should be changing/doing.

Basic Powrtuner use:

Hook up your powrtuner, walk through the steps to activate it, upload your .bin file off your car. Go to the powrtuner forums and download a stock .bin file for your car and just start comparing and seeing what changes were made, familiarize, all this is done by opening the .bin files in the powrtuner program. Then take the stock .bin and read through jerry's tuner notebook making changes it says and try to learn what each change is doing for you. This will help you get familiar with the different parameters you should be dealing with as a beginner. Always have a couple different .bin files when you first start out so you can have something to fall back to if something goes wrong.

Basic Scanning:
(you can scan with the powrtuner program, but it has been known to have bugs, uvscanning.com is a great solution)

Then after downloading the latest version of uvscan, run the program and you may have to tamper with what com port you use to connect to the car. Connect to the car and it will show the vin # or other things letting you know its connected. Setup the parameters you want to scan, the pids/parameters you want to scan for should be whatever is needed for using eddies tool and then a few others if you want (i'll update later with a list). Click on scanner and it will pop up with the different pid's, zoom in with the F1 key i think. Here is where you can start driving and seeing what your car is doing and record the scan by hitting start log, then stop log and it saves it. I usually just have one filename and go by the date/time when looking back at different scans. You should refer to jerry's tuner notebook for getting a good scan but the slower you go through different gears and throttle positions, the better. Just think about the thousands of different parameters being calculated and adjusted per second and we are trying to alter about all of these without any bumps or gaps in the charts, the slower, the better at first, the scan file you are saving isn't that big of a file and you can upload multiple 30 minute runs into eddies tool, so don't worry about that.

I need to go to bed now and will update/edit this later, people can add on/change what i said but i noticed we need to have a couple different versions of jerry's notebook so these questions and newcomers can feel a little better about what they are doing.
