Default Holley terminator x problems. Please help

Hi All.

So I have a 73 Camaro, LS, whipple. M6, ID1050x. I was using the oem computer last year and I always seemed to have low rpm slight issues. So I figured that I'd upgrade to a holley terminator x this winter.

I installed it.
Started right up
Drove it for about an hour.
Noticed still having low rpm driving issues.
I figured it can only be 1 of 3 things.
1) dirty injectors
2) bad plug wires
3) faulty coil

Anyways that's not the issue. Just giving some background on my thinking.

So I started with maybe having dirty injectors.

I removed the injectors ( which to do on a whipple motor you have to disassemble the whipple) got them cleaned and checked. There was a small amount of dirt in a few of them, but nothing to be concerned with. I put them back in and reassembled. I also added a new 10 micron fuel filter. It was a 100 micron.

The car hasn't run since. It only runs on 3 cylinders.
I checked wiring.
Both head grounds are secure.
Spark at all plugs
Noid light shows all injectors firing
Same program as was running before.
fuel pressure good.
I get an rpm. When cranking.

In my search I noticed when taking the supercharger in and out I stepped on the main holley power feed. It looked like it might have been unplugged slightly. I plugged it back in and it acts the same. Could I have blown up the computer?

And to add to it. I can't get registered onto the holley forum. I've tried twice and I can't get in. I tried emailing the administrator, but it comes back as undeliverable. I called holley tech line and didn't get any advice there.

Sorry, I'm at wits end.

Thank you very much for reading.

I replied once but it seems to have disappeared.
Two suggestions, Double check the injector harness and make sure it's plugged into the correct injectors, People have them wrong to many times.
I run a Dominator ecu but this may still apply. If you have a good copy of the tune reload it, I had a battery lose power over the winter and when I started the truck it ran terrible. I ran a log and everything seemed fine. I ended up reloading the tune and it fixed it.

Luckily the injectors labeled. The coils aren't, but I traced the wires back.

I redid the tune when the problems started. No change.

Thanks.

Try a log...
Key on, then start a log, then try to start.
Review the log.
Don't know why you can't log into the Holley forum.
I can post a link to this thread over there, if you want.

Here's the Holley forum administrator's email addy.
He said:
All he has to do is email me with his username and I'll register him in minutes. d c f 1 5 0 @ c o m c a s t . n e t.

Once you get registered, intro yourself, and go to the Term X forum.
Be prepared to post your tune file and datalogs up ft, as that'll be the first thing asked for.
The files have to be zipped, in order to post them.

HTH,
Chuck
