Somebody here local has a complete tbi system removed from a motor home. Ecm is the 8747. How does that ecm compare to the 7747? Is it as easy to program, more or less features?

You know it's bad when your car is on the EPA's 10 most wanted list!
Found thread on gen3 site said 8747 was not as program able due to heavy vehicles needing more grunt than go. Also is set up lock up tc.
79 Cherokee WT QT Golden Eagle white with gold windows "Pigger" only blows hubs the night before a road trip or the clodest night of year. Has only been towed cause of stupid.
No repin required. Direct swap for most C3 ECMs.
It's individual sensors that are different between applications.
8747- no knock
8746- added IAT
7747- knock
Then you have the less commons ones like the 6299, 4288, 8062....
all had various trans applications
The C3 ECM used the 2732 chip for most applications.
