Are you asking about an E92 ECM (2014+ Sierra / Silverado 1500 series truck) ? You could adjust the calibration parameters with TunerPro, if you wrote a corresponding XDF file. TunerPro will not read / write (i.e. flash) OBD2 controllers, so you would need to find another means of doing this. Probab...

Scanning using TunerPro requires the correct ADX file, and an interface (cable) that will support this ADX. Jayme at Delcohacking.net developed a rudimentary ADX for the 512 Kb PCMs, so I'm guessing this is the ADX (or one similar) that would be included with your eBay purchase. The interface cable ...

That looks very similar to the "free" (read only) LS1 Flash Tool that Antus from PCMHacking.net had been developing. There are only one or two OBD2 XDF files (for the 512 Kb PCMs) available for free on the internet. That doesn't mean these don't exist, they are just not publically availabl...

I don't think you will find a free XDF for an MEFI 3 ECM.

MEFI Burn sells a basic MEFI tuning package for $595. It is based on the TunerPro platform.

There are several separate process involved. The ability to Read the programming from the ECU / ECM / PCM is one. The ability to Write the programming into the ECU is another. The ability to Edit the programming from the ECU is yet another. The first step is to Read the programming from the ECU, and...

Writing an XDF using TunerPro RT is relatively intuitive, once you get the hang of it. Open TunerPro RT. Open the BIN from the ECU / ECM - if you have one to use. This is not absolutely necessary, you can create an XDF in isolation without opening a BIN file, but having the correct BIN open lets you...

If you have an AVT-852 and Dimented24x7's read-write utility, then you can program the 0411 PCM. Dimented24x7's XDF is nothing short of amazing, and it should have what you need to rework the programming for a normally aspirated 2001 5.3L engine. The XDF is missing a lot of the transmission and spee...

With OBD-II vehicles you need a means to read the bin from the PCM (in this case a 12200411), and then write it back in again, after making changes.

With the correct XDF file you could use TunerPro to edit the bin file.

What read / write program were you planning on using ?

Thank you !

I updated to the latest version of the software (had a very old version), and now it displays correctly (GM E38 MAF table).

Thanks again ... awesome software !

Sorry if this question has been asked and answered, I searched without success.

I am trying to write an XDF for a GM OBD-II application, and cannot figure out how to get 32 bit floating point data to be properly displayed.

Thank you for any help.
