emu weird troubleshooting
I am not sure where to start - I have had the EMU running for quite a while... and all of a sudden the car died during a drive and I can turn the engine but no spark or start.. its got 550s so I cant use the regular ecu to test anything else..
my laptop detects a new EMU (brand new) but no lights ever come on and it never comes online so im assuming its not getting power but - what lines need to be connected so you can at least connect to upload the map on an EMU?
if i can at least start by troubleshooting that basic step - it might kick me off in the right direction to be able to drive the car again!!!
Thanks again!
(as a random test - i did try going back to the EMU thinking the car might TRY to start and just kick on flood and die.. but it didnt even give a fuel smell that i thought might happen... )

i fried 2 EMU's in about 2 years. had a problem on one where the ignition output on it died and no spark at all just fuel. i would contact Greddy and ask for replacement if it is new. call 9495888300 ask for Brian D very helpful guy. he will try to diagnose and than give u a return number for your unit. best way to go if under 1 yr old. good luck.

wow so elementary.. im fairly annoyed with myself.. on the main harness i believe (to the ecu - ie original factory harness) white/red is the power right? from ignition? yep.. not getting power... i checked the fuses... so must be a break somewhere i guess in the line .. maybe i can run a new one.. any idea where it runs to??? i assume the fuse box... but it would help to have a general guess where to trace this puppy - ive reconnected and tested all the other wires and so far so good

Turns out the issue was the main relay- it wasnt closing all the way so it wasnt getting enough power through the car
took the cap off - push the switch all the way in .. bam car comes on.
i used : http://neomiata.com/garage/1994_Miat...20Diagrams.pdf
to trace all of the wires and the relay function.
