Well howdy Shane,

Nope, not my car, belongs to a chap in KY who has absolutely wrung this thing out for 35,000 miles on carbs before the switch to ITB's - still doesn't smoke under high load. Hadn't ridden in a good old 2.7 in years ....my sensory receptors especially tuned on this occassion mind you what with my sphincter grip'n the seat.

Mine is the old dusty trailhorse below. As you know I do the PWR (Pat Williams Racing) website as well as his PatWilliamsRacing Channel on YouTube and have set that up to auto post updates to his FaceBook. As for tender ministrations to your own machine, shoot him a note, I'm merely the Internet Court Jester from across town, Pat takes care of all the business.

paulgtr: though these systems run open loop maps (just like the factory race machines), for final tweaks and full refinement following dyno development work, you run a cable from the ECU to a very high quality 02 sensor. You have the option of dynamically updating the map while underway (called "learn") or merely monitoring AFR's while making drivability notations for manual map alteration afterward. As visible in the pic below, my car was the mule for the PWR EFI Turbo conversion. 6 years ago I drove thousands of miles with two different engines in the above scenario and a manual map revision's being performed in that pic.

After years of engine mgmt development, fully funcional maps are very methodically derived these days. This car's running a cable merely to get the last bit of efficiency out of interstate/cruised mode for that extra bit of sparkle as this system enables new levels of refinement to be achieved with high performance/mod'd powerplants.
