Try this:

https://www.crossfire.homeip.net

It's a secure connection and you'll have to click the security info popup and it's slower but I think it should work!

What error do you get?

This is very strange, everyone should be able to surf through a secure connection. Do online shopping sites (like summitracing.com) work on your system???

It just comes up and says that it can't find server or DNS error. I went through all of the secure connection stuff, started downloading and then the shell error page came up
All other pages I can view

Thanks Marck :cool
Actually I was trying to get on the site from work and couldn't. I just tried it at home and no problem. Must be something with the firewall at work

The Ecm is in but I will need to do some fine tuning with the prom,it's a little sluggish when I tromp it.The wiring was easy enough but I still have some extra wires and will have to do some more research on which ones go where,if I had made a pigtail in stead of hard wiring the dratted thing I wouldn't of known the difference,but I didn't trust the old connections.The ones I'm concerned about are the canister purge and the air switch,the others are for the Ecell, a ground and the hood sol.The hood sol.I figure I can use a 160 degree temp.switch off the intake or heads.Will post more when know more.
