ya mean PG7? lol
but yeah, it's in the pg7 family, but 86-87 tegs have vacc advance, and the 88-89's have electronically controlled timing.
even though both ECU's say pg7 on them, the electronics are totally diff. in them and they will not work in each other's application. i have plenty of the 88-89 pg7's, but they just wont work!

i only need one to test some drivabilaty issues. i've checked everything in the whole efi system except for another ecu. these ecu's are mounted on the floor under the front passenger seat, and often get water inside them.
if anyone has an 86-87 car sitting around, and can help me out, give me a yell!
