99 'Vert update Well I set it on the ground tonite! Did a base tune on it. Idle and some Code clearing. Fired it off last night open headers. Hit the key and it started! It even idled...for a while 
Well today I came home and stuffed the Y-pipe in it and hooked up the one O2 Senser I did Have an Extention for. Set it on the gruond and loaded a base starting point tune Jim and I whipped up. First thing I learn is My software loads the whole file and not just strings like HPT. So three minutes later I get to start the car. No run. I play and get it running and start turning the T-Blade screw to adjust the IAC and TPS.
I get to where I am idling good but does not sound right. More then just cam. I check wires and coils, all is well. So I got for a drive. A very UN-impressive drive. On the way back the SES starts flashing "LOOK AT ME" Grab the scanner (A new MAC I LOVE!) and it says I have an Injector fault. So I get home and sure enough one of the injectors is not plugged in.
You know LS1s like having ALL the injectors plugged in as well as LT1s
So I do some more Idle adjustments and head back out on the road...where I quickly find the car will Haze the tires all the way through 2nd to 60MPH!!!
MUCH happier! SO now I will borrow a Extention from Steve(thanks!) and get ready to tune it. It REALLY needs that Stall converter I am having built now that is for sure!
So far with almost no real tuning it sound good and runn's so i am guessing it is a step in the right direction...OH and it is out of my shop!

Looks like Tranzor is pulling his 231/237 out. What you gonna stick that in? (seems like you're doing every car in the NW lately, so I just figured.....)

And speaking about tuning Ellis, I just stumbled across this thread:
With the release of hptuners 1.6 there's a new table that wasn't available for editing before, the IAC position vs effective area table. I think this could be useful for getting desired IAC position to match actual IAC position.
I think a problem people run into is when they drill their throttle body or adjust their set screw, the tb has more effective area than the pcm knows about which means the pcm will think it has to open the IAC more than it has to to get the same airflow. If you look at the IAC position vs effective area table, it is 0 up through 12 (which is in mm^2 if i remember right). Which leads me to believe the stock tb hole has an area of about 12 mm^2. If you drill the tb or adjust the set screw, you're increasing the area to more than 12 mm^2 so you should adjust the table to match. That could be done by simply shifting the table to the right.
Interesting, eh? I think I'll try messing with that table...
