Hi everyone.
Were facing difficulties trying to use launch control with potentiometer. Were now running it with a simple setup with two switches. One in the clutch pedal and the other on top of hand brake lever. This setup works fine.
Now to the problem. I was trying to adjust max revs by 10k ohm potentiometer, +5v from ec36 pin 28, ground from common ground 30 cm. from box. We measured nice 2,5v. with the potentiometer turned half the way. So this all should be good.
We tried to connect the signal to some inputs in the ec18 but it seems they are nnot connected to the board. So we pulled the board from the box saw that the ec18 pin 1 (ch.0) is connected to upper left corner of the board with jumper wire.
So is this knock channel?? Can we undo this mod cause we do not use this input at all??
The same goes to ec18 pin 2 (analog ch.5) its run to the upper left corner, another knock channel??
Should we solder off these jumperwires and run a wire from ec18 pin 2 to mcp3208 leg 5 marked on board by JP19??
There are 4 holes in square shape, I was wondering if it is the top left corner of these holes?
If so, do we need to protect the input with resistor??
We had to do the soldering job when we did the push buttons for the launch. We used ec18 pin 16 (ch.1) and soldered a wire from pin 16 to bottom-right corner of the four holes under mcp3208. It has internal pull-up to 5v.
Im sorry for the absence of any photos. If needed, I'll try to take some. I have tried to read all the info I could about the analog inputs but I just couldn't get the info I wanted.
