94-95 1.8L no tach signal
just installed the megasquirt yesterday, and the car is running great.
thanks very much for all the posts, they are a HUGE help.
I have followed this diagram
with 2 exceptions.
The first one wasn't hard. you have to connect the 2K(LG/W) to pin26 on the MS. this gives 5v to the TPS for it to work.
The other one is the on that I'm stuck with ....
from the diagram you have co connect 1B with 2I with a 1k resistor for the tach to work. The thing is .... it still doesn't work ....
Do I have to build a Tach output circuit in the MS and connect it?
Which one ?
what pin should I connect it to ? 2I ?
thanks again guys
