Im new when it comes to megasquirt however have read around the topic considerably and have used megajolt successfully in the past.
Ive got some issues with my current setup unfortunately. I have attached photos to be referred to if need be
Unit was bought second hand a few years back from eBay.
Currently I can't connect it to my Mac at all. Mac side of things I've got the serial to usb driver installed and checked it using terminal so I'm happy there. I've also continuity checked between the cable and ms. Power is getting to the board and its earthed also.
I've power checked it on the 12v as well as the 5v areas using this guide apart from being unable to find s12.
"You should find the same voltage as the battery voltage on the following points: S12, S12C, the center legs of Q9 and Q12, the left (non-banded) end of D3, the left leg of U5, and the left (banded) end of D9.
You should have 5 volts at the following points: S5, the two +5V holes in the proto area, the right (non-banded) end of D9, the right leg of U5, the left (banded) end of D19, and pins 1, 20, and 31 of the CPU."
in addition to this the squirt when I got it had a coil mod done to it (you can see in the photos) I have removed the wiring to this mod where it solders to the board and converted it to run EDIS (like when I ran edis on jolt) it also has msns_extra daughter board v2 wired in.
Has anyone got suggestions on where I go from here as I'm completely stuck now. Thinking of getting a bluetooth adaptor to work around the usb serial one if that makes a difference
