Ok so those are a 512k is the other VZ one a 411?

So ls1a ecu's were pre 1999.
ls1b ecompases both P01/P59 ecu's.
Pre99 & P01 is 512kb
P59 is 1024kb
P01 is blue/red connector
P59 is Blue/Green connector
Apart from some minor pin changes and slightly different shape on the green connector, it's almost plug/plug between the 2. You can file down green the connector plug and away you go
Ok awesome so are the P59 a simple plug and play? Or do some pins need to be moved around
There was a huge stink over on the Corvette forums about this and supposedly 1 dude had it figured out but wasn't talking. I need to update my software to view a ctz, but are there any weird tricks or asspain other than a full flash of that tune onto my P59 in my 2004 Z06? I picked up a blower for it and really want flex fuel ability.

There is a current thread on LS1tech.com regarding this, let me see if I can find it...
I think I saw it too. I'd found more info on the swap but apparently not on the Corvette Forum because when I checked back there I couldn't find what I'd remembered reading.
