MEMCAL problems: Not solved, but much much better
I followed y'all's advice and bought Craig Moate's GP1 kit (http://www.moates.net/product_info.php?products_id=41) I used one of the included chips with the best bin I had and walked out to the car.
Plugged it in and no fan came on....no autoXray communication, but no 'limp home' mode either. Motor wouldn't start.
Grabbed all 5 previously burned chips, all made the fan turn on and limp home mode.
Took a break, grabbed the romulator and EUREKA! There's LIFE in the car!
So. other chips weren't burned right, the new chip most likely doesn't have the bin in the right location, so everything's now electrically sound, but the code's not in the right place. (near as I can tell)
The chips he included are 27SF512's....severely huge compared to what the ECU expects. So, I'll hit a little more research, but I wanted to thank your input. This sucker's CLOSE!

THE CAR IS A FREAKIN MONSTER!
And drives well behaved enough to throw the keys at my wife.
Damn this feels good!

The bin stacking I used is a feature built into TunerPro RT...
I suspect you don't need to stack it, so much as find the offset the ECU expects to find the code at.....unless you've got a MEMCAL with a selector to use different bins for different uses. That's the REAL reason for the stacker.

Nah, mine is doing the same exact thing that his was, so I figured that it had to be the way I'm programming the chip.
Somewhere I read to start at 4000 on the bin.??
I'm figuring it out.
thanks

I think it depends on the chip size and model. On the chips Craig Moates sells I doubled the bin and wrote at 8000.
Due to vagaries od working with address lines in chips, you can READ more than may be on the chip as once to get to the chip's address limit, it wraps back around to the beginning of it's address space and keeps going. So knowing how much and exactly WHERE to put it is critical.

It is called "Bin compiler". It is on his "old web page".

Using the pocket programmer 2, the layout of numbers in the boxes on the right side of the screen above hex format are:
00000
08000 buffer start
0FFFF buffer end
This will put the 32K on the 512 chip right where it needs to be.
