You might also enable VIN change?
Here in CA it is mandatory that the VIN matches for smog testing.
There are probably other states that have a similar requirement.

It can be changed via hex editing though, and doesn't break anything.
Seems that portion of code is not included in checksum.

I can't speak specifically for the individuals who worked on a free flash.
I think in Dimented's situation he accomplished his goals and life got in the way of continuing?
He was very helpful when I emailed him during my $OD MAF install.
Pretty sure $ didn't really have anything to do with his LSFlash project?

Fixed.

I didn't recall that I had initially locked down the VIN (preventing it being changed). That's what happens when you try to complete something that you started years prior.

The VIN should normally be at the primary location. Sometimes it may be at the alternate location.

Just make certain not to make any changes, if the original displayed parameter is not in proper VIN form. Do NOT change the leading cell designated as "NULL".

Changing the non-VIN area would likely result in a bricked PCM.

What is the required equipment for data logging and flashing this PCM using this .xdf?

XDF files are for use with TunerPro software. TunerPro is basically freeware - a small donation is all it costs. To log data using TunerPro requires a corresponding ADX file.

TunerPro will not flash (read / write) an LS1 style PCM. It is editing software. People will use various means to flash the PCM.

XDF files for the LS1 PCM (0411) have been around for a number of years, thanks mainly to Dimented24x7.

The original XDF files for this PCM were actually a series of smaller XDF files (you would load an XDF file to adjust the Fuel System parameters, then you would have to load a different XDF file to adjust the Transmission parameters).

I created one large, all encompassing XDF file, then did my best to make it look a little more like a commercial tuning software. I also incorporated all segment Checksum calculations.

I'm familiar with Tuner Pro, what I'm asking is after editing in TP, what are people using to flash/read with? Are there adx files for the 0411 and TP?
