External TBI driver
I thought about having this conversation privately, but maybe other people on the board are interested.
Jon, where did you get that injector driver schematic from? It looks like only half that circuit would be required for someone using a 747 or 746 with dual TBI, since there is already one injector driver in the ECM.
I just won two TBI units on ebay, $31.00 each for the 350 versions. A 747 wiring harness is in the mail as well. Now all I need is an engine and car to put it in.
I'll be building a test bench first to get thing figured out. If anyone has any ECM connectors they'd be willing to sell, let me know. No junkyards around here want to let me cut their harnesses. I need some injectors as well. Hopefully broken ones, since I won't be running any gas through them, and I hear that's bad for the injector.
