MS3X Ca18det

[superzaxos]

Hello i plan to use MS3x to my ca18det. but i need the ecu pinout and a shematic diagram with colors because i found so many case that i get confused. I plan to use Vag 4 pin coils and stock TPS, stock CA18 Cas and external Map 3bar GM 3bar sensor. also i need to see how i connect a/c to ecu and radiator fan because i need them.
Thanks a lot

Have you looked at the MS3X hardware manual? You can get them all from the Manuals link above.

i know i have see them. but in ca18 cas is 4 wires, i use 4 coils , and i cant see nowhere map sensor. also i must conect them to ms3 or ms3x plug?

See section 6.40.

There are various wiring examples for coils.

Take a look through the hole in the end of the Megasquirt case, the MAP sensor is in there. (Section 3.4.2)

I know is build in map sensor. but i was planing to use GM 3 bar map sensor is that possible?

yes its possible, but the built in MAP is 4 Bar IIRC. maybe its 3, but either way, its built in so use it

Ok i see. So i my cas have 4 wires 1 12v ,1 ground , 1 inner ,1 outer signal. i read the manual and say single coil and coil on plug, single use 3 wires on plug use 4 wires. which method i should use to have 1 VW coil per cylinder?

1 coil per cylinder is the same as coil on plug.
