So this is different. I am driving and datalogging with winaldl. I noticed code 43 was thrown, electronic spark control. But I got no dash warning light. No rough running, no real noticable signs of something wrong. Just a flag on the computer. I recently did a swap, 305-350. Also new esc module for the 350. I just checked that the wires going to the starter and knock sensor were far away from spark plug wires.
Any thoughts on whats going on?
I have been doing some reading and I have seen so far are ppl having this code in conjunction with poor performance and unreliable engine.
i unplug the ESC and the dash light come on, the flag on the computer stays on
the knock sensor is new and the ESC is new with the engine swap. this flag wasnt coming up a wk ago, it was all of a sudden today i flipped through the tabs in winaldl and it was checked off. the car runs great, like nothing is wrong. i can feel a slight difference b/w this wk and last wk vibration wise, its just slight though. i am assuming the ignition module went, thats the last piece of the system. i plugged in my old knock and grounded it and my old ESC ( they came off of my old running 305 that came out) and started the car and the flag was still checked.
