I think I am beginning to understand.

The $12, $A5, $12P is the "operating system" that is also stored on the memcal.

I was confused about changing the bin file to one that couldn't be read in Tunerpro by the same xdf. I thought the definition was set by the ECU type...

Am I new to this.

I agree, that is a good solution.

Yes, thats right the number is the operating system, and the xdf defines where the settings are for that operating system. There are multiple operating systems for each ecm, and in the later ones, even revisions so you have a, b, c etc.

The P suffix was added by forum member VL400 who reverse engineered the whole thing for the earlier ECM generations and added the after market features. This is why its the best by a large margin, and why you can put it on compatible computers even if its got a memcal with a different (but related) operating system.

Just some more info on setting the flex table up.... you can see in Antus example the min and max of the CTX is set to 50 and 151, and this is fine, however it means you get less resolution in the cells of the table.

if for example you set it to min = 90 & max = 100, this will give you almost 1 degree per cell.

you have to remember, outside of the table values it uses the last value, so you dont need to have the full range of numbers in the table, only enough to define your on/off points.

also to note, and i guess its personal preference, the option there to have it only work if the engine is running.
