I decided to modify the bin with $32B It's a 88 corvette.
I have many bins to start from , including the one read directly from the stock car.

What is NOT clear to me is that if I try to see the same bin with a 6E in TunerPro, I see different values!

With 32B the values seems good calculated (displayed). With 6E they seems completely out of range.
Some scalars and flags seems perfectly correct, some completely different.

example on scalars:
Fan 1 Turn On (AC on)
Fan 1 Turn Off (AC on)
Fan 1 Turn On (AC off)
Fan 1 Turn Off (AC off)
in 32B I see values like 104.74c°..107.75 c°
in 6E i see crazy -6.25 F° 3.91 ... and obviously its not C° to F° conversion

I also noticed that the location for the same scalars are different on 6E vs 32B. This explain the different values.

Others scalars (example base timing = 5.98 deg) are the same on both XDF.
BUT in this case the location is the same (1C).

Is there some operation to perform on bin (or on xdf) to "align" the same scalar/flags addresses location?
Thanks

Not easily. To move the scalars and such to match would need to also re-assemble the code into a BIN. Otherwise the firmware would be using the wrong locations.

These are different pieces of software. A BIN is a combination of hard-coded data and programming instructions which operate upon that data. Think of $32 as Windows 9x and $6E as Windows 2000. They are the version of the programming that's running on the ECM. The data tables, flags, and scalars that you want to modify is like all your settings and files. Depending on the operating system they will be located in different places and may not exist at all. So you can't completely translate the settings - some you could move directly by hand, but others like the MAF tables in $6E, don't have an easy translation to $32 since $32 uses pulse width tables and completely different logic such as startup using a 9th injector in place of the main 8....

It would require a specially made piece of software to do the translation. To my knowledge no one has written such a program. No doubt it could be done by promoting the user for some inputs. It probably would not yield a perfect result but would likely run.

If you are interested in writing such a program, the disassembled and commented code for both $6E and $32 are over on gearhack. I'm quite sure th community would thank you for such an endeavour.

Another anaolgy:

It's like using an old map of the city you live in, from say 75 years ago, versus using one from 5 years ago. Some things will be in the same place, others will have changed.

Use the appropriate XDF for the BIN you are using, don't make it more complicated than it needs to be.

I thank you all.
I agree on all.
My question started by my WRONG assumption that many '165 cars born with a $32, where "upgraded" here in that board.

This wrong assumption started by the fact that there are many threads comparing $32 to $6E.
Having the same '165 I was sure that the two (6E and 32) were interchangeable.

So, to use a 6E in a originally equipped 32B car, It's mandatory to start with a BIN that is developed with a 6E mask?
Could I have some example on 16Kb bin good to be used (as starting point) on a originally 32B car?

A lot of folks start with ARAP, an '89 y-body BIN. Need to make a change to get better crank to run. Some times the fan outputs need to be inverted (option bit), and VATs disabled.

Then for an '89 Firebird there is AUJM (L98, auto).
Then for an '89 Camaro there is AUJN (L98, auto).

Could you elaborate on that? What changes need to be made? Do you mean faster startup? I haven't heard that mentioned before in this context.

Thanks!

I made the reccomended changes - I copied the complete ARAP Crank PW Multiplier vs. Ref Pulse table, and changed all the 0.0 entries to 0.5. My cold start this morning was close to perfect. I will continue to evaluate. I'm going to compile a complete list of my $6E changes needed for 86 to 88 retrofit and post it.

The two missing pieces that don't get mentioned is the long crank fix, and the fan switch setting. It's taken me a couple months to figure this stuff out and the guy I bought my initial chip from didn't know about either of these tweaks. Begs the question why is he selling chips but I guess it was cheap.....
