Re: EPROM Programming

Thanks all,

I have spent the last week searching the old E-mail archives and then looking 
at all the links on the GMECM site. I was up til 4 in the morning once 'cause 
I got addicted to all the great info I was finding. In particular, I saw that 
the TPI ignition module adds its own advance without the ECM hooked up which 
solved a problem I was having. Plus, I have asked a lot of questions at 
TPIS.com, Turbocity, Thrasher-ep.com etc. Its not that I don't understand but 
I get different answers from all the vendors. Just trying to sort out what's 
propaganda and what's fact. Thrasher's site seems to contradict what TPIS 
says, etc. So I thought I would just write my own chips. It just seemed like 
a horrendously long task to burn a chip, drive it, change it, and so on. Dr. 
Plecan, since you obviously now know what a perfect chip can do, how do the 
aftermarket chips, (Hypertech, TurboCity, TPIS, etc.) stack up to your work? 
Are they close or are they way behind? How close can they get just by you 
giving them your engine specs? Turbocity actually brags about the ability of 
their chip man. I can't believe they could spend the time you have and make 
it profitable for them. 

Last, it seems that the emulator in the WINBIN link would really reduce the 
chip perfection time. Is this program a viable project? Why hasn't this been 
done already by Diacom? Actually, Haltech E6GM may be the same thing but I 
gathered it was not a GM ECM but some sort of less featured copy.

Anyway, I at first thought this site was sponsored by GM, but now I realize 
that Steve Ravet and other members donated their time to this build this and 
I wanted to thank them and everyone else who contributed. Its pretty awesome.
