I've been fretting about not having the Midget in the garage. Turns out, there's enough to do that by taking the Midget OUT of the garage, I've been able to really focus on getting some essential things done that AREN'T sitting 45 miles away.
This whole throttle body thing came together rather effectively. If it wasn't the only thing DIRECTLY IN FRONT OF ME, I might have pushed it off. But now, I'm in striking distance.
ALL BUNGS ARE PLUGGED. The frost plugs are pressed in and JB Welded into place, air tight, and actually, kind of attractive -

One thing I have yet to determine is this. On the last TB, there is a mounting flat for the TPS that hasn't been drilled or tapped to locate the sensor, and it has no clamp-down feature for radial adjustment. Additionally, the sensor screw holes are not slotted for adjustment.
I have about 85 degrees of motion on the butterfly shaft, and the TPS has about 120 degrees of range.
The sensor can be calibrated through the software, but I'm wondering if there's a "best position" that I should be using on the initial TPS placement set-up. I'm looking to drill and tap the flat on the TB in the appropriate position.
I've got that question posed to the tech folks at Holley. They've been really good about getting back to me so far.
I asked this because my dad and I once installed one of the VERY early Pro-Jection systems on a 390 Ford, and I recall that I needed to set the sensor at a predetermined ohmage, although I can't remember if it was at WOT or idle.
My gut tells me that if I place the sensor in such a way that the TPS operates radially in it's middle range, I can program the ecu to "learn" the range, and I should be good, but I'm waiting to confirm that.
