I have a 92 305 TBI car with a 1228746 ECM, and 2732A EPROM type. My problem is which chip do I use

At http://www.jdr.com/interact/item.asp...-epromcircuits I find two chips with the 2732A number...

2732A-250 - EPROM(D2732AF1)4KX8 250NS 21VPPG 24CERAM - $5.49

or

2732A-200 - EPROM(2732A-2F1)4KX8 21VPPG 24CERDIP - $5.89

what's the difference between these two? I'm a true newby at this stuff, and I would greatly appreciate any help from any seasoned chip burners.

Also, all I need to burn chips is the Pocket Programmer, EPROM Eraser, a bin editing software(WinBin or TunerCat), and one of the chips listed above...right?

Thanks in advance for any help! Hopefully I will soon be burning my own chips

 

You are probably going to want to buy a AT29C256-12PC,
AT29C256-90PC ECT. THE -# Stands for eprom speed in nano seconds(12pc)=120ns (90)=90ns.
these proms you can just write over them w/o the use of an eraser and will last for many of burns.

 

opps,sorry -disregard that last message i thought you were a 730 ecm. I just realized you are a TBI not TPI.

 

thanks for trying tho...

 

With my new adapter, you SHOULD be able to use the 29C256 PROMs with the TBI setups. Just need a little more testing...

 

Thanks!!
I'll try that
