Hey everybody im wanting to get into tuning on my truck, I just finished building the motor in it and am going to get it broke in then turn my attention to tuning. Im running Jodys programing right now, but would like to be able to do my own programing, (nothing against jody great guy) How do you all like this software? Im thinking pretty seriously about buying the package just looking for a little input on it.

thanks Corey, One question would the base files that i get be set up for my big oil injectors and turbo to just get me into the ball park? Or would i be starting with a file thats a general tune for any stock OBS truck?

with this software i can tune for my 96, question is can on of my friends buy a chip from you and we tune it with the same software? im sure we can i just dont know if you have to buy additional software for the differant pcm code that he has.

I think i found the answer to my own question, $250 per RDT file (pcm code is what im understanding this to be).

I was reading what Corey had posted and I can see a place where there may be some confusion so I wanted to take a second a clarify.

The MDF files (which used to be RDT files) are not changed depending on whether you have modifications or not. They are what they are and are based on the vehicle's PCM family. What she was referring to was that when we send a definition file, we include some base calibrations along with it. These do not include tuning for injectors or any other major modifications. We can provide customized base files for an additional charge.

Other than that, you are correct. $250.00 will get you another definition file to use on a different family of vehicle.

Hope this helps.

Out of curiosity, how many MDF's are there?

There are dozens of .hex definitions....however, there are only about 8 that are worth having for 49-state applications. A few others for the California emissions models.

Take a look here....
http://www.thedieselstop.com/faq/949.../pcmcodes.php3
In the last column there is a "Template". Match the first 5 digits and separate them into groups....then count how many groups contain the same first 5 digits.

For example, AEB0, AEB1, 2, 3, and 4 are all DPC-461 computer codes. However, they each require a different RDT to properly make tuning adjustments because the "template" is different. In this case, it is common practice to use one RDT and corresponding base file to tune with. (I know, preposition at the end of the sentence is wrong!!) To make it more complicated, match the DPC-461 with any other DPC-461 and you can put an AEB3 tune in GDU0-4. As an example, it's common practice to use PMT1 in any DPC-422 PCM.

Ahh that makes sense, So i just ran outside and checked out my pcm code and its a DPC-202 and it has the NAW4 code in it, would there be a better code to base off of than the NAW4 from the link it looked like there were quite a few codes for the DPC-202?

By the way thanks Bill for clarifying that for me it all just klicked for me.

A resounding YES!!

NAW4 SUCKS. TDE1 is the one you're going to want. So, regardless of who your chip comes from, order TDE1. Also tell the operator that you want a 3-4 shift at 41-43 MPH...not 10.
