I just did a refash after lowering my 2 step launch control limit. When reflashing the software listed that it was clearing the memory. Does the ecu memory that stores what it has learned get erased every time you reflash? The car didnt quite feel as fast after the reflash as I did not change anything else. I know it will relearn everything in a few days, so not a big deal, just wondering.

Thanx in advance.

 

It seems to reset fuel trims, octane number etc. However, default octane number is 255 (max) on the ROMs I've seen. I've datalogged acceleration times just a few minutes after reflashing and measured no difference.
