which EPROM to buy?
I just bought the programming stuff today, and I noticed that when I went to order the EPROM's there are a couple different ones that I can get. I've got an 89 camaro ECM, but am currently using a caprice chip. Traxion's article says that I should use a 2732A chip, but JDR lists two EPROM's under this number:
2732A-250 EPROM(D2732AF1)4KX8 250NS 21VPPG 24CERAM &
2732A-200 EPROM(2732A-2F1)4KX8 21VPPG 24CERDIP
-=-edit-=- can I use eeproms instead, this would save the money that I just spent on the digikey eraser-=-
whats the diff? Is there a place to get them cheaper besides JDR? I thought that they were only supposed to be around $3.00, but these are like $6.something.
Also, which bin should I order with TunerCat, just ask for the $61 package?
One extra thing, are there more places where I can grab some info, I downloaded the diy-efi archives along with traxion's article, but they all seem fairly vague as to which parameters change what.
Appreciate any help that I can get before I start burning...

I'm not sure I want to help you because your little yellow guy keeps mooning me.
Seriously though, either one of those two chips will work. The difference seems to be the speed (250 vs 200). I don't believe they make a 2732 chip that is EE, only UV. And I think tunercat comes with the definition file you need which I think is the $42 mask. And I believe tuning 101 or something of that manner has a few things you can pick up on for tuning the 42 mask. Doh, wait a second, the 42 mask is for a 747 and you must have a 746. Well, just check the TC site and it'll tell you what to get.
