Thanks guys!
Yesterday, I drove the car about 775 miles to start the HRPT. For the first venue, I was able to park under a pavilion which was nice during the rain and just sitting around chatting with people:

Two LS4 Fieros are long hauling the tour (mine and Tom Slick)!
More pics of the other Fieros on the tour are in this thread: http://www.fiero.nl/forum/F...1/HTML/096278-2.html

Car look bad azz. I like the wheels. Perfect setup for an 88.

Thanks guys! We all are having a blast!
I posted this video in another thread, but for $50 we got to drive on the Circuit of the Americas track. I appoligize for the video in advance, I started it with my smart phone in its stand, but it over temped and shut down. So I grabbed my trusty camera and held it.
Here are a couple more pics of my fiero out and about:

I am finally back home from the HRPT and spending the weekend in STL with Sara and the girls!
It was great fun with 5 Fieros long hauling: blakeinspace, Tom Slick, Cajun, gtoformula, and fieroguru.
We also saw these others PFF members (or former members) on the trip: ltlgt88, KMFDMFAN, Troy and Elvi (can't remember their forum ID), TXGOOD, 2MidV8, fierocarparts, 3.4Turbo, Rare87GT, fieroX, Jazzman, MustangsBware, infinitewill, and a few others.
The overall trip was 2853 miles for me with the distance to start the HRPT and get back home. My best tank of fuel averaged 27.5 miles (no AC, dropped to 25.0 with AC on and cruise set to 72-74), the worst tank was 19.1 (only a 4.5 gallon top off), and the overall average for the trip was 22.9 mpg.
We started the trip with torrential rain for the first 2 days and ended with 95+ degree temps at the last 4 venues with the last day being 100 degrees. The rain, heat, miles, and rough roads challenged all of our Fieros, but the 5 long hauling Fieros made it to the end with only having minor issues. The only issues with my car were the new DS windshield wiper didn't want to stay on (wire ties fixed it) and had a couple of tail light bulbs go out (replaced). Overall it handled the rain and heat well and continues to be very reliable (but I did identify a sticking caliper and replace it prior to the tour). Within the next week, I expect to pass 30K miles post swap!
This was the first long trip with AC running. When I first started the swap, the AC hose had a leak that I never fully addressed until the day before the tour. So while the AC worked great, it would stall the engine when I came to a stop. Several reasons for this: ** E67 ECM - doesn't have an AC request signal, only clue the ECM has that the AC is on is via the line pressure switch which is hooked up. ** Manual Transmission - I am using the LS4 auto calibration, so it doesn't "see" when I press the clutch, a dedicated manual transmission calibration would work better. ** Aluminum flywheel and camshaft - not much low end torque or rotational momentum, so my engine struggles more to spin the AC compressor at idle than the stock LS4 would. I can feel a significant difference in engine load while launching from a stop with the AC "ON" vs. "OFF".
The tour gave me the opportunity to do more tuning for the AC to avoid the clutch in stalling. In the AC torque table, I doubled the values below 800 (to account for the camshaft low rpm torque loss), then copied the same values into the table up to 4000 rpm (so the ecm adjusts for the load while driving, vs adjusting for it at clutch in). In the BRAF table, I took the airflow at 1200 rpm, used 125% of this for 1600 rpm, and then copied that value to all cells above 1600 rpm. This slowed the RPM drop, especially in the 2000 rpm to 1200 rpm range. This worked quite well, and as I approached a stop, I could clutch in, shift to neutral, and coast to the stop, while the RPMs came down and settled to idle w/o stalling. Now the only stalling issue with throttle blips and some parking lot maneuvers, but I am getting better at driving it in town with the AC on. It only stalled 1 time while driving around STL and the return trip to Champaign.
I do need to revisit my cell phone holder for use as a GPS. It works great, but sitting in the sun and with the display on, it gets too hot and starts shutting programs off, eventually shutting off the phone to allow it to cool down. If I held the phone in front of one of the AC vents, then it would quickly cool down, so I need to find a cooler (temp wise) mounting location.[This message has been edited by fieroguru (edited 06-30-2016).]

Are those wheels Enkei kojins? I've been looking at those but in matt black. What size wheel and tires are you running?

Staggered wheels look perfect on a Fiero due to its smaller front nose and bulkier rear end. I'm surprised more people don't do it.
Very nice work, as always.

Awesome! The exact sizes I was looking at! They look amazing.
