on your notebook make sure only the bare essential programs are running in windows (systray and explorer). This will make it alot faster. You probably wont need a virus scanner or anything like that if you arnt connected to the internet.

Great observation Shawn, so the dhp pcm may be fine but was having a hard time with the mini afc. A scan tool seems to be needed with the use of the afc in order to properley set it up? I have read somewhere that the afc 2 is more prone to fail than the afc 1.1, which is why they still sell the earlier version I guess?
No, the problems I was having with power loss at 90 mph and 130 mph limitation was running with the new DHP alone and no AFC 1.1. I only installed the AFC 1.1 about a week later and only for 2 days until the wife complained about the stalling. That'* when I removed both. :(

I'm going to reinstall the AFC 1.1 tomorrow and see if the little internal lights are still functioning. The instructions say that if the lights work then the AFC is OK.

I guess it will just run lean until it blows up, no big deal.
My fuel pressure regulator should help with the lean running for now and when the new DHP gets reinstalled that should really help to blow it up good.

So I re-installed the AFC 1.1 and set it at 101%. All diagnostic lights are functioning, so I'll try it for today and see if it throws any codes...........

The AFC worked fine today.....at least the car ran fine, idled great and didn't throw any codes.

I removed it again anyhow. No more blind trials for now and I don't think I really require it with the fuel pressure increased a few psi.

The loss of power after I removed the DHP module and replaced it with my original PCM was too much to bear :( ............so I re-installed it again.
I'm not going to redline it or drive it too hard until the replacement arrives .....ya right and I can live with the SES being lit. Its benefits still outweigh the few problems it presents.
If it takes another month for the replacement to arrive, I just may have a case learn done on this one to clear the light and get my security system working in the interim.
