Well after a few major set backs like a busted knee and the passing of my daughter this year , i finaly had time to shoe horn the 1.6 miata motor into my little ute
(photo attach) which was a big friggen head ach lol but not as much as i am having working out the wiring for this project. Now i am using a megaquirt 2.2 and because
this ute is new to fuel injected engines i thought i would go with a Megasquirt Power distribution Board and harness from DIYAutoTune but i having problems getting my head around it in setting it up, and i would like to ask you guys for your imput. First off i am using part of the orginal loom from a mx5 engin bay ie: the injectors, coils, igniter,and sensors.
Ok the coils there is a large Blue wire coming of the harness now i know this is power can i connect this to the ignition ?? without a fuse or should i add one ??
Next is the igniter also a large blue wire which i assume would go to the same place as the Coils one would go, there is 3 other wires i have concerns about, a b/w,a br/y, a br, now i know these 3 wires go to the factory ECU but how do i work out where they go on the Megasquirt Power distribution Board. And there is a Tach wire as well coming out of the igniter, but there is a tach output on the distribution Board.
Now for the injectors, the distribution Board has 4 signal connectors and 4 power connectors for the injectors, as you guys would know there is only 3 wires 1 power and 2 signal wires, so what would you reconmend in wiring this up ??
As for the CAS that has me totaly baffled, there a 4 wires coming out of it as the schematic show 3 of them go to the factory ECU but bugger if i know how i am suppose to wire it in to this distribution Board ?
As i am using the distribution board (relay board) it has its own Relay Cable which connect between the megasquirt and the distribution board and there does not seem any other way to connect more bits to the megasquirt other then though the relay board ??.
Now just one more i have been reading post on the forum but alot are not to clear, if i want to remove the factory AFM can i just replace it with the IAT sensor kit from DIYAutoTune.
Any help or directions would be very appreciated
