Buddy of mine at work has a 92 ford ranger with a 2.3l 4 cyl engine. He recently put a turbo on it out of a thunderbird.
It actually runs, but not great, so I have managed to convince him that piggy backing a SD will be a fairly easy thing to do and we can get rid of his MAF and get his fuel tuned.
As for spark, initially I thought it used a EDIS system, but it doesn’t, it has a dual spark set up, that ad near as I have been able to research, is basically a modified TFI with the PIP and SPOUT as the crank input and spark output respectively.
Does speeduino support the Old ford TFI? It’s been too long ago I don’t remember if what the SPOUT signal needed to look like.
The PIP signal, is a basic trigger, just on the crank.
The dual spark ignition module takes care of deciding what coil to fire based on another input from the crank sensor.
The spark control is not the main priority at the moment, and i think if I ca get his fuel tuned up good, we will look into getting a crank wheel and sensor off of a later model that uses a 36-1 crank wheel, and ditch the factory low res dual spark all together. But it would be nice to get control of the timing till that point, and it’s only 2 wires.
So if SD does support the old TFI ( ford thick film ignition)
How would I set up the ignition output? It’s been 15 years ago but I know I did it with megasquirt, if I recall I think it was just a 50 duty cycle logic level output.
